Product serial number
PCL-2000 series products are polycaprolactone（PCL）diols which polymerized by small molecule diols and caprolactone monomer. The PCL diols synthesized polyurethane will get better hydrolysis resistance and low temperature flexibility than the adipic acid based polyesterdiols, and better heat resistance, weatherability and higher strength than the polyether diols.
PCL-3000 series products are PCL triols whichpolymerized by small molecule triol and caprolactone monomer, which can be used to improve the flexibility of surface coating as raw material or additive, and also can be used to improve the low temperature performanceof PU foam as raw material.
Special PCL polyols
PCL-Hydrolysis resistant Series
This series products are modified to obtain high hydrolysis resistance based on the original PCL-2000 series, which can be used as raw materials of high hydrolysis resistance polyurethane elastomer and polyurethane adhesive, and can also be used as toughening agent for epoxy resin.
PCL-Polyether modifying Series
This series products are PCL polyols which polymerized and modified by caprolactone monomer with polyether polyols as the initiator.
PCL-2200T made PU elastomer retains the strength of PCL polyol and also improves the low temperature characteristics, water resistance and abrasion resistance of the PU elastomer.
PCL-3400P is a PCL triol which polymerized and modified by caprolactone with PPG as the initiator, which can improve the reactivity and tear resistance of its products.
1. The elastomer prepared with polycaprolactone polyols has excellent wear resistance, weather resistance and hydrolysis stability.
2. The elastomer prepared by polycaprolactone polyols has better low temperature flexibility and resilience.
1. PCL polyols can be used as reactive diluents and modifiers for polyurethane, acrylic acid, polyester, epoxy resin and vinyl coatings.
2. Reduce VOC in the coating, improve color and luster, obtain the required balance of hardness and flexibility, but no affect of film performance.
●Adhesive & Sealant:
1. The adhesive made of PCL polyols get excellent adhesion to different substrates.
2. Get low viscosity and long viscosity duration, which improves the sizing convenience.
3. Get good hydrolysis stability,flexibility and uniformity for adhesive and sealant.
