Water-soluble polyester chips spot supply PET Sanfangxiang CZ-302 pet bottle grade polyester chips
PET Raw Materials Granules Polyethylene Terephthalate Resin
Polyethylene terephthalate (PET) is synthesized by transesterification of dimethyl terephthalate and ethylene glycol or by esterification of terephthalic acid and ethylene glycol. Bishydroxyethyl phthalate, and then polycondensation reaction in the system. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It is a common resin in daily life and can be divided into APET, RPET and PETG.
Advantage
1. It has good mechanical properties, the impact strength is 3~5 times that of other films, and it has good folding resistance.
2. Resistant to oil, fat, dilute acid, dilute alkali, and most solvents.
3. It can be used for a long time in the temperature range of 55-60 ℃, short-term use can withstand high temperature of 65 ℃, and can withstand low temperature of -70 ℃, and the mechanical properties of high and low temperature have little effect on it.
4. The gas and water vapor permeability are low, and it has excellent gas, water, oil and odor performance.
5. High transparency, can block ultraviolet rays, good gloss.
6. Non-toxic, tasteless, hygienic and safe, can be directly used in food packaging.
