Technical Datasheet BG 825
Product Description:
Polyethylene Terephthalate bottle grade chips (highly viscous) is a condensation polymer produced by a continuous meltphase polymerization process followed by a solid state polymerization process, with an I.V of 0.75-0.85. The products has an excellent transparency and gloss, an outstanding gas barrier against oxygene and carbon dioxide, and outstanding toughness and impact strength.
Applications:
