Polyester reflective material
Polyester is a type of polymer containing ester functional groups in its main chain. Polyesters can be divided into two categories: "Saturated Polyester" and "Unsaturated Polyester". They are usually made by polycondensation of one or more polybasic acids (anhydrides) and one or more polyols. It has excellent stiffness, excellent toughness, lightweight, impact resistance, and good chemical stability. Applied Materials with specific functions can be developed through processing technology.
