CAPROMER Polycaprolactones
CAPROMER Polycaprolactones
CAPROMER™ Polycaprolactones are specialty polyols for high-performance polyurethane (PUR) applications. BASF’s manufacturing process results in polyols of high quality with low catalyst levels for consistent reactivity of the PUR reaction. Low-viscosity di- and trifunctional polyols are available as components for isocyanate-based formulation systems. CAPROMER polycaprolactones offer outstanding low temperature flexibility for thermoplastic elastomers used in technical applications and coatings.
BASF’s CAPROMER polyols are used where high hydrolytic stability is required together with good light-fastness. They exhibit a very low melting viscosity for easy processing of PUR elastomers. CAPROMER-based PUR dispersions are an excellent choice for many textile and leather applications. For coatings applications the low viscosity facilitates high-solids and solvent-free formulations. Such coatings offer excellent weatherability and chemical resistance.
