TINUVIN PUR 866
TINUVIN PUR 866
Tinuvin PUR 866 is a high performance UV stabilization package designed for polyurethane systems (e. g. TPU, CASE, RIM flexible foam applications). Tinuvin PUR 866 is particularly efficient in thermoplastic polyurethane (TPU). This product can also be used in polyurethane coatings on tarpaulin and flooring as well as in synthetic leather.
Applications
This product provides outstanding UV stability to polyurethane systems. The increased effectiveness over conventional UV stabilizer systems is particularly pronounced in transparent or light colored TPU applications.
Tinuvin PUR 866 can also be used in other polymers such as polyamides and other engineering plastics including aliphatic polyketone, styrene homoand copolymers, elastomers, TPE, TPV and epoxies as well as polyolefins and other organic substrates.
Features & Benefits
This product offers superior performance and increased productivity over conventional light stabilization systems:
- Excellent initial color
- Superior color retention during UV exposure
- Enhanced long-term–thermal-stability
- Single-additive solution
- Easy dosable
