PET structural foam has good specific stiffness, specific strength. Compression, tensile, shear and bending strengths are excellent.
PET foam core also has good dimensional stability and easy to process, suitable for a variety of processes. It is an ideal core material for lightweight & high-strength composite sandwich structures.
It provides excellent fatigue resistance, impact resistance and very low water absorption. Heat and sound insulation are also very good.

Features:
High exothermic peak tempertaure resistance, up to 180C
High performance weight ratio, good impact resistance
Resistance to many chemicals, almost no water absorption
Low flammability, self-extinguishing from fire
Suitable for a variety of composite molding methods: Vacuum infusion, spray up, hand lay-up, vacuum bagging
Good impact strength
Low resin absorption
Good sound & thermal insulation

Application:
marine, surface transport, aerospace, and wind energy industries
