FREQUENTLY ASKED QUESTIONS

What is PET?

PET, or polyethylene terephthalate, is the most common thermoplastic polymer in the polyester family. It is used in the form of a film to give some of our products increased rigidity and tensile and elongation strength.

What is microcellular polyurethane foam?

Microcellular polyurethane foam is a fine structured, open cell urethane foam that provides excellent resistance to compression set at a reasonable price point.
