Applications
Industrial
Product Description
Eastobond™ 19411 is a terephthalate-based copolyester which is amorphous. It offers excellent organoleptic and gas-barrier properties. Eastobond™ 19411 has low postextrusion crystallinity and a low softening point, enabling heat-seal bonds to be achieved over a temperature range of 95°C to 205°C.
