Pet Resin

Top quality virgin PET resin bottle grade

Polyethylene terephthalate (PET), chemical formula (C10H8O4)n, is made from dimethyl terephthalate and glycol transesterification or esterification of terephthalate and glycol to synthesize dihydroxyethyl terephthalate, and then polycondensation reaction. It is a crystal type saturated polyester, which is a milky white or light yellow, highly crystalline polymer with smooth and glossy surface. It is a common resin in life, which can be divided into APET, RPET and PETG. It has excellent physical and mechanical properties in a wide range of temperatures, up to 120â??, and excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but it has poor corona resistance, creep resistance, fatigue resistance, friction resistance and dimensional stability. Advantages: 1. Good mechanical properties, impact strength is 3~5 times that of other films, good folding resistance. 2 oil resistance, fat resistance, dilute acid resistance, dilute alkali resistance, resistance to most solvents. 3. Can be used in the temperature range of 55-60â?? for a long time, short-term use can resist 65â?? high temperature, can resist -70â?? low temperature, and high and low temperature has little impact on its mechanical properties. 4. Low permeability of gas and water vapor, and excellent resistance to gas, water, oil and odor. 5. High transparency, can block UV, good luster. 6. Non-toxic, tasteless, good health and safety, can be directly used for food packaging.

Polyester chips usually refers to the polyester raw materials obtained from the polymerization production is generally processed into about 4 * 5 * 2 mm or so sheet particles. 1. According to the composition and structure can be divided into: blended, copolymerization, crystalline, liquid crystal, cyclic polyester chips and so on; 2. According to the performance can be divided into: coloring, flame retardant, antistatic, moisture absorption, anti-pilling, antibacterial, whitening, low melting point, viscosity (high viscosity) polyester chips, etc.; 3. According to the use can be divided into: fiber grade polyester chips, bottle grade polyester chips, film grade polyester chips (mainly different process indicators). Fiber grade polyester chips according to which the content of matting agent tio2 can be divided into: super glossy (big glossy), glossy, semi-matte, (full) matte polyester chips. There are also cationic polyester chips. Polyester applications now include fibers, various types of containers, packaging materials, films, films, engineering plastics, and other fields.

Sustainable Choices: Recyclable nature encourages manufacturers and consumers to opt for sustainable packaging solutions.

Pet is an opalescent or light yellow highly crystalline polymer with smooth and glossy surface. It has good creep resistance, fatigue resistance, wear resistance and dimensional stability, small wear and high hardness. It has the largest toughness in thermoplastic plastics: good electrical insulation performance, little influence by temperature, but poor corona resistance. It is non-toxic, weather resistant, chemical resistant, stable, low water absorption, weak acid and organic solvent resistance, but not resistant to hot water immersion and alkali. PET resin has high glass transition temperature, slow crystallization rate, long molding cycle, large molding shrinkage, poor dimensional stability, brittle molding and low heat resistance.
