Rifeng TR Easy to process FST structural foam.
Rifeng TR is a closed-cell, thermoplastic and recyclable, PET rigid structural foam with excellent fire, anti-smoke and anti-toxicity (FST) properties. It is suitable for lamination with all types of resins and processes. It is easy to thermoform and process mechanically. It also offers great chemical resistance, is resistant against UV rays and does not absorb water. Curing and post curing at increased temperatures are unproblematic as it is highly heat-resistant without showing post-expansion and outgassing.
Rifeng TR is the ideal core material for structural sandwich applications requiring high fire resistance.
