Capa™ 2201

Technical DataSheet | Supplied by Perstorp

Capa™ 2201 by Perstorp is a standard grade linear polyester diol derived from caprolactone monomer, terminated by primary hydroxyl groups. Exhibits outstanding flexibility even at low temperatures, low viscosity, gloss, hydrolytic stability, excellent strength, UV resistance and abrasion resistance. It shows a lasting outdoor performance for polyurethane materials. It has low impurities and is non-toxic, biodegradable, easy to process with short cycle times, shape and apply. Provides strong adhesion on difficult and sensitive substrates and shows consistent crystallization. It possesses excellent mechanical properties even at low density, wide interval of service temperatures, consistent and narrow molecular weight distribution and consistent reactivity. It helps in remarkable cold flex fatigue, improved compression sets and improved tear strength. The product has been specially developed as a low reactivity alternative to Capa™ 2200 for use in cast polyurethanes where extended processing times are required. In addition, Capa™ 2201 also provides much more easily controlled pre-polymer manufacture. Applications include automotive components, automotive industry, footwear industry.
