Supply PET motor film, PET film manufacturer, optical grade PET film, optional-film supplier
The characteristics of heat shrinkable polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and heat shrinks more than 70% in one direction; ordinary polyester is a crystalline polymer, ordinary The PET film can only get a heat shrinkage rate of less than 30% after a special process. To obtain a polyester film with a higher heat shrinkage rate, it must also be modified. That is to say, in order to prepare a polyester film with high heat shrinkage, it is necessary to copolymerize and modify ordinary polyester, namely polyethylene terephthalate. The highest thermal shrinkage rate of the PET film modified by copolymerization can be as high as 70% or more.
