CAPA® polymers are used in the manufacture of polyurethane adhesives in all forms, including TPU's, solvent based, aqueous dispersions, hot melts and reactive hot melts. CAPA® thermoplastics are hot melt adhesives and are also used in combination with PU systems in reactive hot melts. Typical end uses are:
- Reactive hot melt structural adhesives
- PU sealants
The benefits provided by CAPA® products are:
- Low viscosity systems aids wet out and improves processing.
- Excellent adhesion to different substrate including leather.
- CAPA polymers are aliphatic and hence are light stable.
- CAPA polymers are biodegradable.
- CAPA polyols provide excellent oil and UV stability.
- Very good hydrolysis resistance.
- Low density in comparison to other polyester based polyurethanes ca. 4%.
- Excellent low temperature properties due to a low Tg of ( 60 °C) and wide working temperature range.
- Highly crystalline CAPA thermoplastic polymers.
- Outstanding tear strengths.
- Consistent open time.
