Polyethylene Terephthalate (PET) is a hard, stiff, strong, dimensionally stable material that absorbs very little water. It has good gas barrier properties and good chemical resistance except to alkalis (which hydrolyse it). Its crystallinity varies from amorphous to fairly high crystalline; it can be highly transparent and colourless but thicker sections are usually opaque and off-white.

4PET® is the registered trade mark for Polyethylene Terephthalate (PET) compounds produced by 4PLAS, we offer a wide range of PET compounds which also includes post consumer value added recycled grades. These cost effective products give competitive advantages not only in material costs but also in environmental regulations and commitments.
