Polycaprolactone Polyols: Elevating Polyurethane Performance
Polycaprolactone polyols are a special class of aliphatic polyester polyols, used in the soft block segment of high-performance polyurethane elastomers. The polycaprolactone polyols are produced with very low acid values (significantly improves hydrolytic stability), perfect hydroxyl end-group termination (excellent reactivity and high molecular weight control), narrow MW distributions (low viscosities including in the prepolymer form) and low glass transitions that affect good low temperature flexibility in polyurethane elastomers.
Using our broad range of unique polycaprolactone polyols, formulators can custom tailor polyurethanes to achieve greater levels of performance to enhance the capabilities of existing polyurethanes or enter new applications by displacing other material systems (for example rubber, epoxies, etc.). Our polycaprolactone polyol grades are designed to address multiple parameters that can improve the performance and service life of a broad range of polyurethane components.
Polycaprolactone-based high-performance polyurethanes are used in applications that include cast elastomer parts, coatings, adhesives, seals, foams, laminated packaging, TPUs, leather and textile coatings, Paint Protective Films (PPF), ink binders and dispersions. Caprolactone polyols are particularly beneficial for urethane formations used in corrosion protection and water-immersion applications. End-use industries include automotive, industrial, construction, mining, oil and gas, rollers and wheels, aircraft, healthcare, sporting goods, water treatment, electrical/electronics, textiles, and footwear to name a few.
