Capa™ 7201A

Technical DataSheet | Supplied by Perstorp

Capa™ 7201A by Perstorp is a block co-polymer diol, initiated with alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl). It is derived from caprolactone monomer and polytetramethylene ether glycol. It has low melting point. Specially designed for the production of polyurethane elastomers having outstanding physical properties at low temperatures and good retention of properties at high temperatures. Used in the formulation of high performance microcellular foams and solid elastomers where highly dynamic conditions are encountered.
