XPE/ IXPE Foam Function

Functional properties of XPE/ IXPE foam

a.Thermal insulation
After high-temperature cross-linking and foaming, a porous bubble structure is formed, and the multi-layer bubble barrier effectively blocks thermal energy transfer. The CTF experimental data attest : the lowest thermal conductivity ≤0.035w/m.k, and the highest thermal conductivity ≤0.095w/m.k.The larger times foaming ratio of foam, the lower thermal conductivity will be.
Application: Automobile ventilation pipe, air conditioning pipe, HVAC insulation cotton, roof reflection insulation, Radiant Floor Heating, battery insulation..
b.Waterproof, moistureproof
After high temperature cross-linking and foaming, a continuous closed-cell structure is formed, and the multi-layer closed-cell structure effectively blocks liquid penetration. The CTF experimental data attest : the minimum water absorption rate is ≤0.1% and the maximum water absorption rate is ≤0.4% at 23℃-22h, which conforms to the IPX7 waterproof level. The lower times foaming ratio of foam, the lower water absorption rate.
Application: car waterproof membrane doors, camera gasket, waterproof foam tape, outdoor moisture-proof mat, surfboard panel, floating board, floating blanket on water floating…
c.shock absorption
After high-temperature cross-linking and foaming, a tight closed-cell structure is formed, and the multi-layer tight closed-cell structure effectively buffers the force. The CTF experimental data attest : the minimum compression set is ≤2% at 25%-23℃-22h, and the maximum compression set is ≤11%. The lower times foaming ratio of foam, the smaller compression deformation will be.
Application: artificial turf shock pad, sports knee pad substrate, sports helmet lining, product packaging inner support, indoor anti-collision soft pad, sports mat…
d.soundproof, noise reducing
After high-temperature cross-linking and foaming, a multi-layer closed-cell structure is formed, and the multi-layer closed-cell barrier effectively blocks the transmission of part of the sound source. The CTF experimental data attest that: the 5mm thickness foam has the sound insulation Rw=13dB in the air, the impact sound improvement ΔLw=20dB.The foam is thicker, sound insulation effect is better.
Application: Floating floor shock absorption underlayment, floor sound insulation underlayment, electronic crosslinked polyethylene foam vibration damping pad, nano-silica thermal insulation carpet, automobile ceiling lining…
e.weather fastness
After high-temperature cross-linking and foaming, a three-dimensional molecular structure is formed, which has stronger structural stress than the linear molecular structure. the CTF experimental data attest : 70℃/-30℃-12h no aging phenomenon; UV radiation exposure-spray-condensation-12h has no obvious change; the highest temperature resistance is 100℃/-60℃.
Application: roof insulation material, graphene floor heating underlayment, electrical insulation liner, engine insulation pad, car sunshade…
f.chemical resistance
After high-temperature cross-linking and foaming, it forms a tight closed-cell structure, crosslinked polyethylene foam has a strong tightness, and has excellent resistance to chemicals such as acids, alkalis, and organic solvents.
Application: electrode gasket, anti-seepage ointment gasket, , medical foam tape, bottle cap gasket…
g.Lightweight,softness
After high temperature cross-linking and foaming to form cell structure, the volume expands and the quality is almost unchanged. The foam foaming ratio times is larger, foam density is smaller , foam lighter and softer . The experimental data of CTF: the highest Shore hardness is 65°, the lowest hardness is 13°. 35 times the material is about 28kg/m³, which is the preferred lightweight material for industries with high demand for lightweight.
Applications: car ventilation ducts, car floor mats, car ceiling linings, car waterproof membrane doors, car sun visors, car dashboards…
h.Thermoforming
After high-temperature cross-linking and foaming, a three-dimensional molecular structure is formed, which has stronger structural stress than the linear molecular structure. CTF experimental data: the highest tensile strength – transverse ≥ 140Kpa * longitudinal ≥ 160Kpa, elongation at break – transverse ≥ 210% * longitudinal ≥ 230%, tear strength – transverse ≥ 11KN/m * longitudinal ≥ 13KN/m.
Application: sports insoles, foam wall stickers, strawberry blister trays, 3D simulated animals, ESD blister trays, dental braces…
i.Environmentally , non-toxic, odorless
After high temperature cross-linking and foaming, without chemical residue and no peculiar smell; no halogen, no toxic gas will be produced even when burning and heating; the content of formamide is extremely low, and there is no toxic and harmful substances such as formaldehyde and heavy metals. The CTF experimental data: it meets the odor 3.0 standard of automobile interior lining and passes the EU export Reach / Rosh testing.
Applications: car ventilation pipes, HVAC insulation pipes, baby playmat, baby cuddles pad, outdoor moisture-proof pads, child seat cushions…
