| TORAYPEF™ is long, semi-rigid, sheet-like foam that features closed cells produced via electron beam cross-linking. With its features such as light weight, heat insulation, shock-absorbing properties, moldability and non-absorption, the product is widely used in a variety of fields, including molded interior automotive parts, building insulation, joint filler, pipe covers, and other industrial materials as well as daily necessities, health and sports equipment. TORAYPEF™ is long sheet-like foam featuring an expansion ratio of 5x to 50x and a 100% closed cell structure which exhibits superior cushioning, shock-absorbing and heat insulation properties, water resistance and superior chemical properties, with a wide range of potential applications. - Superior Shock-Absorbance. The product exhibits superior resilience and flexibility as well as excellent absorption of impact energy. It combines comfortable cushioning with firmness due to its closed-cell structure.
- Superior Heat Insulation. The thermal conductivity, water absorption and water vapor transmission rates are extremely low and the product is well suited as a thermal insulation material.
- Superior Waterproofing and Buoyancy. With its closed-cell structure, the product does not absorb water and shows excellent resistance to water and moisture and is highly buoyant.
- Superior Aesthetics. Cross-linking via electron beam ensures that the surface is smooth with fine textured bubbles.
- Superior Workability. Additional processing steps such as cutting, slicing, molding and adhesion are easily achieved.
- Superior Chemical Resistance. Compared with other plastic foams, TORAYPEF™ is virtually immune to the effects of chemical agents.
Processing:- Cutting and Punching. Cutting is generally performed using a vertical cutter but cutting can also be performed using scissors or a razor. Punching and boring can be performed using a Thomson punching machine.
- Slicing: The product can be easily sliced using a slicing machine which employs a rotating knife.
- Thermal Fusion Bonding: The product can be thermal fusion bonded to other PEF objects as well as steel or aluminum plating. Work can be performed simply by using a hot air gun or a Teflon-coated thermal plate.
- Molding: Both vacuum molding and pressure molding are possible. Moldability varies among different product grades; the drawing ratio of PE grades as determined via a straight assay is approximately 0.5 while the drawing ratio of PP grades varies from approximately 0.6–1.0.
- Surface Treatment: Various surface treatments such as embossing, flocking and printing can be performed.
