Transparent PET plastic roll for Coronavirus Transparent Protective Face Mask pet sheet is a milky or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, abrasion resistance and dimensional stability are good, with low abrasion and high hardness. It has the greatest toughness among thermoplastics: good electrical insulation performance, little influence by temperature, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, weak acid and organic solvents resistance, but not hot water immersion, alkali resistance. Transparent PET plastic roll for Coronavirus Transparent Protective Face Mask pet sheet resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, crystallized molding is brittle, and low heat resistance. Through the improvement of nucleating agent and crystallizer and glass fiber reinforcement,Rouleau en plastique transparent pour animaux de compagnie pour le coronavirus Masque en face de protection transparente has the following characteristics in addition to the properties of PBT.
1. Heat distortion temperature and long-term use temperature are the highest in thermoplastic general engineering plastics 2. Because of high heat resistance, reinforced PET is immersed in a solder bath at 250 ° C for 10S, which has almost no deformation and does not change color, especially suitable for the preparation of soldered electronics Electrical parts:
3. Bending strength of 200MPa, elastic modulus of 4000MPa, creep resistance and fatigue resistance are also very good, surface hardness is high, and mechanical properties are similar to thermosetting plastics.
4.Because the ethylene glycol used in the production of PET is almost half cheaper than the price of the butanediol used in the production of PBT,Rouleau en plastique transparent pour animaux de compagnie pour le coronavirus Masque en face de protection transparente and reinforced PET are the lowest prices in engineering plastics and have a high price-performance ratio.
