High-Performance & Eco-Friendly PET Foam Closed-Cell Honeycomb Core
Introduction
As a new type of thermoplastic structural foam core material, PET foam is gradually becoming the focus of attention in the material field due to its unique performance advantages and environmental protection properties. It takes polyethylene terephthalate (PET), which is homologous to the common beverage bottles in our daily life, as the core component. Through recycling or new material processing and advanced foaming technology, it finally forms a high-performance engineering material with a uniform closed-cell honeycomb structure. In application, PET foam mainly acts as the core material of sandwich composite panels and can be compounded with various high-strength panels such as fiberglass, carbon fiber, and aluminum panels. Compared with traditional materials, PET foam is known as an excellent alternative to PVC foam due to its outstanding balance in performance, cost and environmental protection, providing a new choice for material upgrading and sustainable development in related fields.
