Parameters of Wholesale thermoforming black conductive plastic sheet film roll
Characteristics of Parameters of Wholesale thermoforming black conductive plastic sheet film roll:
PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good abrasion resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics: good electrical insulation, low temperature influence, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents, but not immersed in hot water and alkali. PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, and crystallization molding is brittle and low heat resistance. Through the improvement of nucleating agent and crystallization agent and glass fiber reinforcement,
In addition to the properties of PBT, PET has the following characteristics:
1. The heat distortion temperature and long-term use temperature are the highest among thermoplastic general engineering plastics;
2. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, the creep and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to thermoset plastics;
3. Since the ethylene glycol used in the production of PET is almost half the price of the butylene glycol used in the production of PBT, PET resin and reinforced PET are the cheapest among engineering plastics and have a high cost performance.
