Black PET stick

PET plastic molecular structure is highly symmetrical, has a crystal orientation capacity, and therefore have a high and a film-forming properties. PET plastics have very good optical properties and weather resistance, amorphous PET plastic having good optical transparency. In addition PET plastic with excellent frictional wear resistance and dimensional stability and electrical insulation. PET bottles made with a high strength, good transparency, non-toxic, anti-penetration, light weight, high production efficiency and thus subject to a wide range of applications. PBT and PET molecular chain of similar structure, most of the properties is the same, but the main chain by two methylene into four, so the molecule is more supple, more excellent processing performance. PET is a milky white or pale yellow highly crystalline polymers, the surface smooth and shiny. Creep resistance, fatigue resistance, abrasion resistance, wear small, high hardness, the largest thermoplastic toughness; electrical insulation properties, little affected by temperature, but poor resistance to corona. Non-toxic, weather resistance, resistance to chemical stability, low water absorption, resistance to weak acids and organic solvents, but intolerant of hot water immersion, not alkali.
