Flame retardant foam materials and technologies

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.

Introduction of Linear Low Density Polyethylene Foam Plastic

ldpe

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 foam material

ldpe

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.

New Material IXPP foam for Automotive Interiors

There are two commonly used plastics for automotive interiors: general-purpose plastics (PVC foam, PE foam, PP foam) and engineering plastics (PA, ABS, PC). The current PE materials have poor weather resistance, are sensitive to environmental stress, are prone to aging, and have insufficient heat resistance. Ideally, low-density polyethylene foam materials should be used at 80°C, and high-density polyethylene foam materials should be used at 110°C. In order to better meet process requirements and reduce the weight of materials, IXPP foam was developed.
IXPP is made of polypropylene (PP), AC foaming agent, etc., mixed and extruded, irradiated by an electron accelerator, and foamed at high temperature.

IXPP foam performance:
It has good thermal stability (use temperature can reach 130℃);
It has good mechanical properties such as toughness, tensile strength and impact strength;
IXPP material is environmentally friendly and low VOC (with industry test report).

The main application occasions of IXPP foam:
Car Dashboard,
Car Door panels,
Car Console,
Car Decorative surface,

60% lighter than ordinary materials

Compared with PVC foam material, the CO₂ index of PP foam material is improved by more than 40%;

Suitable for application processes with thermal stability up to 120°C;

High processing technology and high processing efficiency;

Compared with TPO foam, it has better scratch resistance and compression recovery.

XPE is Polyethylene chemically cross-linked foaming material

At present, there are two process routes: molding method and continuous extrusion method. The production of  XPE foam by the molding method is intermittent and cannot be produced continuously. The product is piece by piece, not a continuous product. The foaming ratio is low, the density is large, the product thickness is single, and the thin product cannot be formed at one time.
Changyuan Tefa adopts continuous extrusion production, horizontal continuous foaming production, advanced production technology, the product does not cause environmental pollution during the production process, and the product has good chemical and physical properties, such as a wide range of foaming magnification (currently Our company can produce a variety of products between 3-40 times to meet the different needs of customers), low density, thin thickness, can be produced in 2mm-12mm one-time molding, smooth surface, high elasticity, high toughness, easy to two Secondary processing, more extensive uses.
