Thermal stabilizer trimethyl phosphate TMP-modified polyester technology to improve product performance polyester

 

Polyester film (BOPET) are used as packaging materials throughout, the market increasingly demands progress against it. Thermal stabilizer trimethyl phosphate TMP-modified polyester technology to improve product performance polyester, by copolymerization, modification, surface modification coating essentials, modified polyester raw material, can improve the BOPET film Performance in isolated, high temperature, UV, heat-sealable and so on. Polyester (PET) refers to the ester group-containing thermoplastic polyester short. As a member of a saturated thermoplastic polyester, polyethylene terephthalate plastic packaging materials used throughout most kind. It can be used for a variety of bottle molding containers, sheets and films.

Among them polyester film (BOPET) the largest application market is flexible composite materials, 50% of the total amount. People living water is usually beneficial improvements to the packaging material requirements are also getting higher and higher, for example, require a high isolation, high heat resistance, high transmittance, high light, low haze, anti-ultraviolet radiation, fire-retardant , heat-sealable, meet food hygiene requirements and so on. Obviously, ordinary polyester film can not meet these requirements, we shall be in accordance with the requirements of a difference, from the perspective of the difference must be modified PET.

Our production and export of trimethyl phosphate, exported to Japan, South Korea, India, the United States and other countries. 80 percent of exports.

Polyester thermal stabilizer trimethyl phosphate normally used (TMP) or triphenyl phosphate (TPP), their low phosphorus content, a large addition amount, an amount causes excessive drop melting point PET, transparency and impact ʱ?? France introduced a new thermal stabilizer triethyl phosphate (TEPA), is reported to make PET low haze, transparency and progress. Development of new, efficient, non-toxic, non-polluting heavy metal catalyst is a polyester production skills progress and an important part. Currently, the vast majority of the catalyst used in the polyester production apparatus antimony catalysts are, for example, antimony trioxide, antimony acetate, antimony ethylene glycol and the like. The fear is that antimony belong to heavy metals, is not conducive to environmental protection, and even may be hazardous to human health. Therefore, to develop free of heavy metals, no environmental pollution, polyester catalyst needs very healthy, especially as PET food packaging materials, the more a sense of urgency.
