Product Description
PET Resin is cream or pale-yellow crystal, with smooth and shiny surface. Resistance to creep deformation, fatigue resistance, abrasion resistance
and dimensional stability are perfect. Small wear and tear but high hardness, its toughness is the largest in thermoplastic.
The electrical insulation of PET is perfect and little
be affected by temperature, however, poor corona resistance. PET is non-toxic, weather resistance, and anti-chemical stability is very good. PET is low water absorption, resistance to weak acids and organic solvents.It is a condensate of terephthalic acid and ethylene glycol, together with PBT, referred to as thermoplastic polyester, or saturated polyester. PET Characteristic: is milky white or light yellow highly crystalline polymer, the surface smooth and shiny.

Application
Features:
1. Good electrical insulation performance, less affected by temperature, but poor corona resistance.
2. Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant.
3. The glass transition temperature of PET resin is high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is poor, the crystallized molding is brittle, and the heat resistance is low.
4. The heat distortion temperature and long-term use temperature are very high among thermoplastic general engineering plastics.
5. Because of the high heat resistance, the reinforced PET is immersed in a solder bath at 250°C for 10 seconds, and it hardly deforms and does not change color. It is especially suitable for the preparation of electronic and electrical parts for soldering.
Application:
1. PET is mainly used for fibers, and a small amount is used for films and engineering plastics.
2. Another use of PET is blow molding products, which are used in various bottles, such as water bottles, carbonated beverage bottles, and oil bottles.
