Perstorp is the world leader in caprolactone derivatives for PU elastomers under the Capa™ brand. The wide choice of monomer, and polyols allows system house prepolymer producers and specialized elastomer formulators to develop elastomers that are designed to perform in all conditions. If you are looking for a partner to enhance your elastomer properties and achieve greater durability in the final product then we can support you on a global basis.
Capa™ bridges the performance gap
Traditionally polyether is chosen for elastomers because of its good hydrolytic stability, while polyesters are chosen for their mechanical performance. Capa™ polyols bridge the performance gap by offering a combination of hydrolytic stability and high mechanical performance.
Durability for longer service life in harsh conditions
Capa™ significantly outperforms its rivals in durability derived from exceptional abrasion resistance, excellent hydrolysis, UV resistance and other mechanical properties. With Capa™ you can develop longer-life or new elastomers that maintain their performance and shape even in the toughest of conditions, such as in jounce bumpers, automotive sealing, hydrolytic seals and gaskets, coaster wheels, mining screens and even sport shoe soles.
Ease to process and more cost effective
Capa™ polyols low viscosity and low melting point facilitate easier handling compared to high melting point adipates. Added to this these narrower polydispersity polyols contribute to a tighter manufacturing specification, which means a more consistent quality with less out of spec products, concessions and complaints.
