Aliphatic polyester polyols for polyurethanes
The DIEXTER product line consist of polyester polyols with molecular weight between about 500 and 5000 Dalton (Da), used for polyurethane production in the coating, adhesive, sealant and elastomer (C.A.S.E.), imitation leather and flexible and microcellular foam sectors.
COIM produces polyester DIEXTER starting from organic diacids and polyfunctional diols or glycols.
Polyurethanes produced with DIEXTER polyester polyols have excellent physical and mechanical characteristics: high abrasion resistance, excellent ultimate elongation, chemical resistance and resistance to solvents. Polyesters with high crystallinity rate are also available on request.
