Performance and advantages:
PET is called polyethylene terephthalate in Chinese. It is a kind
of polymer prepared by condensation polymerization of terephthalic
acid and ethylene glycol. According to its state, PET can be
transparent, colorless or white, non-toxic, and has excellent
mechanical properties, especially after stretching orientation. As
the quality index of PET, there are mainly intrinsic viscosity,
melting point, glycol monocondensate content, carboxyl content and
so on. The melting point depends on the regularity of the molecular
chain structure of PET. If there are no side effects in the
synthesis process, the melting point of PET can reach 275. C.
However, it is impossible to achieve this. Ethylene glycol
monocondensate is formed and polymerized into the molecular chain
of PET, which destroys the regularity of the chain and decreases
the melting point. Ethylene glycol content: Ethylene glycol is
formed by dehydration of ethylene glycol at polymerization
temperature. The results show that it is mainly formed in the
transesterification and pre-polycondensation stages. Alcohols
contain ether bonds, which are more flexible and can significantly
reduce the melting point of resins
Use and market:
The comprehensive performance of PET resin sheet is excellent and
conforms to the world tide of environmental protection. The demand
of all countries in the world has increased dramatically, and the
development of PET resin sheet has been unprecedented. Although the
price of PET sheet is higher than that of PVC sheet and BOPS sheet,
because of its high transparency, high strength, high function,
strong environmental adaptability, strong recyclability (no harmful
gases produced during incineration), it has been widely used.
Mainly used in food packaging containers, industrial packaging
lampshades, etc. Its use is still expanding. At present, the
world's main bottle polyester manufacturers and product
performance, the factory products can usually provide a series of
varieties and brands and performance according to user needs. Acid
content of PET: The acid value is expressed as the number of
carboxyl moles per 1069 resin. The reasons for the carboxyl group
in PET resin are unesterified, hydrolyzed and oxidative
degradation.
