Описание материалов:
COBITECH 2 resin is a PET copolymer, based on terephthalic acid. Its high melt strength make it well suited for the production of expanded sheets, boards, panels, profiles and beads. Foam sheet can be thermoformed. After crystallization the foamed products can withstand temperature exceeding 200°C (390°F) for short time and are susceptible to mechanical finishing.
Scraps of foamed products obtained by COBITECH 2 can be re-used in extrusion without significant I.V. loss. COBITECH 2 is also designed for applications requiring high melt strength, such as blown film.
