Polycaprolactone Polyol

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.

The molecular features of the polycaprolactone polyols manifest themselves in polyurethanes characterized by the following property profiles, many of which are best-in-class performance attributes.

1. Superior Resistance to Hydrolysis: Our polycaprolactone polyols impart exceptional resistance to hydrolysis, ensuring the longevity and stability of polyurethane applications.

2. Excellent Weatherability and UV Stability: The resulting polyurethanes exhibit outstanding weatherability and UV stability, making them well-suited for applications exposed to challenging environmental conditions.

3. Good High Temperature Performance and Low Temperature Flexibility: Achieving a balance between high-temperature performance and low-temperature flexibility, our polyols contribute to the versatility of polyurethane elastomers.

4. Durability, Flex-Fatigue Life, and Elastic Memory: Experience enhanced durability, prolonged flex-fatigue life, and superior elastic memory, characteristics that define the longevity and resilience of polyurethane components.

5. Compression Set Resistance: Our polycaprolactone polyols offer notable resistance to compression set, maintaining the shape and structure of polyurethane products under pressure.

6. Enhanced Abrasion and Impact Resistance: Enjoy improved abrasion and impact resistance, ensuring polyurethane components withstand wear and tear in demanding applications.

7. Chemical Resistance to Oils, Fuels, & Solvents: The chemical resistance of these polyols extends to oils, fuels, and solvents, broadening the range of applications in which polyurethanes can excel.
