There are many types of plastic sheets and flakes with a wide range of uses, among which PET sheet has more good performance.
PET sheet, like other plastics, the performance and molecular weight are closely related to the molecular weight determined by the characteristic viscosity, the greater the characteristic viscosity, the better the physical and chemical properties, but poor fluidity, the greater the moulding viscosity.
PET sheet is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It has excellent physical and mechanical properties over a wide temperature range, with a long-term service temperature of 120°C and excellent electrical insulation.
Electrical properties are also good under high temperature and high frequency, creep resistance, fatigue resistance, friction resistance and good dimensional stability.
PET transparent sheet production of the first condition is drying time and hot air dew point control, drying effect directly determines the physical and mechanical properties of the sheet and production. In the drying should pay attention to the drying temperature and time control, drying temperature and time can neither be too high nor too low.
