crystal apet clear plastic rolls for medical face shield

Description of crystal apet clear plastic rolls for medical face shield 
Crystal apet clear plastic rolls for medical face shield  has excellent physical and mechanical properties in a wide temperature range.
The long-term use temperature can reach 120 ° C and excellent electrical insulation. Even at high temperature and high temperature,
crystal apet clear plastic rolls for medical face shield  is a milky or light yellow, highly crystalline polymer with a smooth and shiny surface .
The electrical properties are still good, but the corona resistance is poor, creep resistance, fatigue resistance, friction resistance, and dimensional stability are all good.
PET has an ester bond, which is usually enhanced in strong acids, strong bases and water vapor.
The disadvantages of improving its processing are slow crystallization rate, difficult molding processing, high molding temperature, long production cycle and poor impact performance.
Properties and physical properties, with glass fiber reinforcement effect is obvious, improve resin rigidity, heat resistance, chemical resistance, electrical properties and weather resistance.
However, the disadvantages of slow crystallization speed still need to be improved, and nucleating agents and crystallization accelerators can be used.
Adding flame retardants and flame retardant drip agents can improve the flame retardancy and self-extinguishing properties of PET.
