Eastar Copolyester 5011
Application/Uses
  • Pen/stationary supplies
  • Toys/Sporting goods
Product Description
Eastar Copolyester 5011 is a glycol modified polyethylene terephthalate(PET). The modification is made by adding a second glycol, cyclohexanedimethanol (CHDM) during the polymerization stages. The second glycol is added in the proper proportion to produce an amorphous polymer.
