PET Foam-Luoyang Siweinuo New Material Technology Co., Ltd

Product Details

PET foam is a renewable thermoplastic polymer foam with a closed-cell structure. It has excellent properties such as flame retardancy, smoke resistance, and non-toxicity, as well as excellent mechanical and fatigue resistance, chemical stability, UV resistance, and low water absorption.

Compared with "sandwich" structural materials composed of resin, fiber, etc., it has the characteristics of high strength, light weight, and strong designability, providing a new solution for lightweighting. It is widely used in sandwich materials in wind turbine blades, rail transportation, ships, building materials, decorative materials and industrial applications.
