Application
Polyester fibers are widely used in the textile industry. Plastic bottles made from PET are widely used for soft drinks, both still and sparkling. BOPET is used in the back sheet of photovoltaic modules. PET is also used as a substrate in thin-film solar cells. PET can be compounded with glass fiber and crystallization accelerators, to make thermoplastic resins.
Typical Applications
Use as film-forming agent.
Use as non-metallic material.
Use as adhesive.
