Rifeng® T is a easy processing PET structural foam.
Rifeng® T is a closed-cell, thermoplastic and recyclable polymer foam with a very homogeneous cell structure, high mechanical properties and an outstanding price / performance ratio.
It has an extraordinary resistance to fatigue, is chemically stable, UV resistant and has negligible water absorption. It is thermally stable during high temperature processing and post curing without after expansion or out-gassing. Rifeng® T is designed for easy use with all resin systems and processing technologies.
Rifeng® T is ideally suited as a core material for a wide variety of lightweight sandwich structures subjected to static and dynamic loads and/or exposed to elevated temperatures during manufacturing.
