PE/ XPE/ IXPE/ IXPP/ ESD foam industry news

The difference between XPE/IXPE foam and EPE foam

What is EPE foam?
EPE stands for Expandable Polyethylene,

The main raw material of EPE foam is LDPE (low density polyethylene), which is a non-cross-linked closed-cell structure foam material of physical foaming.

EPE has the properties of waterproof and moisture-proof, cushioning and shockproof, sound insulation, heat preservation, etc., but its mechanical properties are very low, its variability is easy to leave creases, its resilience is small, and it is easy to absorb water.

The price of EPE material is relatively cheap. Therefore, it is widely used. In daily life, we can often see the figure of foam: such as the packaging of fragile gifts such as wine, the inner packaging of hardware products, toys, melons and fruits, and leather shoes. In addition, foam is also widely used in car seat cushions, pillows, electronic appliances, instrumentation, computers, audio, medical equipment, industrial control chassis, hardware lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture furniture, daily necessities, etc. product packaging.

What is XPE/IXPE foam?
XPE foam and IXPE foam are new environmentally friendly polymer materials, safe, non-toxic and tasteless. Compared with EPE foam, XPE and IXPE foam materials have better mechanical properties, are stronger, more durable, and have excellent moisture-proof, thermal insulation and sound insulation effects. XPE foam is commonly used in construction, automotive, sports, packaging and air conditioning industries, such as floor sound insulation mats, floor moisture-proof mats, baby crawling mats, etc.

Which is better, XPE foam or EPE foam?
Compared with price, EPE has more advantages;In terms of physical properties, the parameters of various mechanical properties of XPE foam materials are better;According to the grade of material, XPE foam material is more high-grade;In the packaging industry, as the inner material for product packaging, EPE and XPE have their own advantages and disadvantages. Based on production cost considerations, EPE is more widely used, but in order to improve the quality of packaging, many customers have chosen XPE to fit foam. approach that combines the advantages of both.

How to distinguish XPE and EPE? What is the most intuitive difference between XPE and EPE?
The cells of XPE foam are more delicate and uniform than those of EPE. The cells of EPE foam are often relatively large, and the size of the cells is uneven. For the thicker version of 15mm and 20mm children’s crawling pads, there is another way to distinguish: foam does not need to be fitted, while XPE foam must be double-layered – XPE foam is limited by technology and equipment. The thickness of the thickest XPE material is about 10mm, so the thickened version of the XPE children’s crawling mat is usually realized by high-temperature double-layer bonding. On the side of the thickened version of the crawling mat, careful observation can see the traces of the bonding.

Compare Polyvinyl hloride, Polyethylene to Cross-linked Polyethylene

Polyethylene is referred to as PE, which is a polymer of ethylene and is non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, good electrical insulation.

Polyvinyl chloride, referred to as PVC, is a polymer of vinyl chloride. It has good chemical stability and is resistant to acid, alkali and some chemicals. It is moisture-resistant, aging-resistant and flame-retardant. It should not be used above 60°C, and it will harden at low temperatures. Polyvinyl chloride is divided into soft plastics and hard plastics.

Cross-linked polyethylene, referred to as XLPE, is an important technology to improve the performance of PE. The performance of PE modified by crosslinking can be greatly improved, which not only significantly improves the mechanical properties, environmental stress cracking resistance, chemical corrosion resistance, creep resistance and electrical properties of PE, but also The temperature resistance level has been significantly improved, and the heat resistance temperature of PE can be increased from 70 ° C to more than 90 ° C, thus greatly broadening the application range of PE. At present, cross-linked polyethylene (XLPE) has been widely used in pipes, films, wire and cable materials and foam products.

CYG TEFA’s foam products are made of cross-linked polyethylene (XLPE Foam), which is better than PVC and PE foam.

Cross-linked polyethylene foam

XLPE foam insulation is a chemical or physical method of Structure changed from linear molecular structure to three-dimensional network structure, from thermoplastic to thermoset material, thus increasing the working temperature by 70°C to 90°C, with great mechanical properties.

The global cross-linked polyethylene foam (XLPE) consumption market is dominated by the Americas, with Asia Pacific being the largest 32%。 Regional consumption market, accounting for 48.32% of the global consumption of cross-linked polyethylene foam (XLPE).

Downstream cross-linked polyethylene foam (XLPE) is more extensive, more recently, cross-linked polyethylene foam (XLPE)
It is becoming more and more important in various fields such as construction, auto parts, anti-static, electronic hardware and sports and leisure. Globally, the cross-linked polyethylene foam (XLPE) market is primarily driven by growing demand for construction and automotive parts. Auto parts accounted for nearly 27. 58% of the total downstream consumption of cross-linked polyethylene foam (XLPE), and construction accounted for nearly 23. 85%.
Cross-linked polyethylene foam (XLPE) can be mainly divided into physical cross-linked polyethylene foam and chemical cross-linked polyethylene foam, wherein physical cross-linked polyethylene foam occupies about 92.20% of the cross-linked polyethylene foam market.

Flame retardant PE foam materials and technologies

Plastic foam due to its special chemical structure, determines that most plastic products are flammable products, when burning some will also produce a large number of toxic gases and dust, on human health and the environment have a particularly bad impact. In some cases, foam plastics require certain flame retardant properties to meet the requirements of safe fire prevention, which requires flame retardant treatment of foam plastics.

Polyethylene (PE) foam has only two elements of carbon and oxygen in the molecular chain, so it is very easy to burn, thus limiting the use of PE foam in refrigeration and air conditioning, heating and insulation and other fields as building interior materials, so it can be added flame retardant to polyethylene to achieve flame retardant effect and meet customer requirements.

The synergistic effect of antimony oxides and halogens commonly used in industry plays a role in insulation, oxygen insulation, and flame retardancy. Its flame retardant mechanism is that the two react to generate a volatile substance with a high boiling point of halogenated antimony, which can stay in the combustion area for a long time, not only in the liquid-solid phase can promote the carbonization of the polymer surface, but also in the gas phase can be captured. OH radicals, which prevent the polymer from further decomposing to produce flammable gases. Antimony halide can become a gas at the combustion temperature, which has the effect of heat absorption and cooling, which can prevent the spread of combustion and play a flame retardant effect. Common are antimony trioxide with chlorinated paraffins, and antimony trioxide with decabromophenyl ether. In addition, polyvinyl chloride can also be blended and modified, two or more polymers are physically forced and uniformly mixed together. For example, pe and EVA blending modification can improve its comprehensive performance, especially impact resistance and environmental stress cracking resistance. Some literature mentions the use of lamination molding methods to prepare flame-retardant PE foam, but this technology is currently immature and needs to be further explored.


Linear low-density polyethylene (LLDPE) is a new type of polyethylene resin

which was produced by Du Pont in Canada in the late 1950s and industrialized in the late 1970s. It is a third-generation polyethylene resin with both high-density polyethylene (HDPE) and low-density polyethylene (LDPE) properties. Many properties of LLDPE resin, such as tensile strength, environmental stress cracking resistance and melting temperature range, are superior to LDPE resin. Therefore, cross-linked LLDPE foam is a new type of polyolefin foam product, which has better physical and mechanical properties than LDPE and HDPE foam products. Compared with LDPE melt, due to the low tensile viscosity of LLDPE melt, poor temperature sensitivity of melt viscosity, and higher melt viscosity under high shear, the LLDPE foaming process is more difficult to control and requires cross-linking foaming. The process obtains ideal foamed products. When the ratio of polyethylene foam is 5 times, its tensile strength can reach 1.60MPa, and its elongation at break can reach 236%.

Polyethylene (PE) resin is a crystalline polymer with a linear structure. When it is heated and melted, the force between macromolecules is very small, and the temperature range of the high elastic state is very narrow. When the resin is melted, the melt viscosity is low, so it foams. When the decomposition gas of the blowing agent is not easily maintained in the resin, it is difficult to control the foaming process; PE has high crystallinity and fast crystallization speed, and a large amount of heat of crystallization is released from the molten state to the crystalline state, plus the heat capacity of the molten PE Larger, it takes a long time to cool to a solid state, which is not conducive to maintaining the gas during the foaming process. In addition, PE resin has a high gas permeability, among which low-density polyethylene (LDPE) is more easily permeable to gas than high-density polyethylene (HDPE). These factors will promote the escape of foaming gas.
In order to overcome the above shortcomings, it is usually necessary to cross-link the molecules to form a partial network structure to increase the viscosity of the resin and slow down the tendency of the viscosity to decrease with the increase of temperature, that is, to adjust the viscoelasticity of the resin to meet the foaming requirements.
Polyethylene foam can be divided into two types: cross-linked and non-cross-linked. Cross-linked PE foam is divided into two processes: radiation cross-linking and chemical cross-linking. If it is classified according to the external pressure when the blowing agent is decomposed, it can be divided into normal pressure foaming and pressure foaming.
The development of foamed polyolefin materials has always been a hot spot of research. Compared with the traditional foaming materials of PS and PU foams, the development history of polyolefin foaming materials such as PE and polypropylene (PP) is shorter.
In 1941, a patent from DuPont of the United States proposed the preparation of PE foam, which opened the prelude to PE foam. Later, the Callent Cable Construction Company and other companies also obtained patents for the preparation of PE foam. In 1955, DuPont of the United States produced low-foaming PE. In 1958, the Dow Chemical Company of the United States first adopted the non-crosslinking extrusion foaming method to realize the industrial production of high-foaming PE foam. At present, most of the high-foaming PE in the United States is still produced by this method. In the early 1960s, Japanese companies such as Sanwa Chemical Industry, Furukawa Electric and Sekisui Chemical successively developed and developed cross-linked high-foaming PE, and started producing high-foaming PE products in 1965. At present, most manufacturers are based on the technology developed in Japan. Europe began to produce cross-linked PE foam materials from about the 1970s.
