Webinnovative low- melt/high-shrink, optically clear PET copolymers with soft-hand and enhanced dyeability. Copolymerization of PET using MPDiol glycol can result in significant … PET is copolymerized with other diols or diacids to optimize the properties for particular applications. For example, cyclohexanedimethanol (CHDM) can be added to the polymer backbone in place of ethylene glycol. Since this building block is much larger (six additional carbon atoms) than the ethylene glycol … Zobraziť viac Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, Zobraziť viac Textiles Polyester fibres are widely used in the textile industry. The invention of the polyester fibre is attributed to J. R. Whinfield. It was first commercialized in the 1940s by ICI, under the brand 'Terylene'. Subsequently Zobraziť viac PET in its most stable state is a colorless, semi-crystalline resin. However it is intrinsically slow to crystallize compared to other … Zobraziť viac Resource depletion Compared to the use of petroleum as fuel, however, the amount of crude oil processed into PET is very small.
