GOYENCHEM GGK-670 High Potency Anti-UV for Thermoplastic Polyurethane Elastomer
GOYENCHEM GGK-670 prevents degradation of thermoplastic polyurethane from processing, light and weather, especially for discoloration from sunlight. It does not affect initial color of TPU from synthesis process. Adding UV absorber into extruder from TPU synthesis process, the UVA have to drop into extruder between 2/3 to 4/5 of screw length.

Advantages
- Low volatility, good heat stable and dose not bring smells to the polymers.
- Very good compatibility with polyurethane offering homogeneous distribution during processing.
- Chemical stable, dose not interact with reductant or oxidants used in polymer-ization or curing process ,including easily added to aliphatic or aromatic PU system
- Provide no effect on initial color of substrates.
- Prevents the processing ,light and weather induced degradation of polyurethane product
- Excellent performance of discolor resistant for polyurethane resin system
- High UV light stability and heat stability, does not bring smells to the polymers.
Applications
- GOYENCHEM GGK-670 is used in polyurethanes serius such as Reaction injection Molding(RIM)、PU synthetic leather、cast polyurethanes、PU sealant、adhesive system、leather sofa、massage chair、shoes、balls、clothes、and TPU。
- GOYENCHEM GGK-670 can be used in thermal-plastic polyurethane. In general, it is recommended 0.5 to 1 wt% based on polymer weight.
Packing
- 20 kg or 200 kg net/ drum
Toxicity & Safety
GOYENCHEM GGK-670 can be safety handled without any irritation caused to the skin. GOYENCHEM GGK-670 should be stored in a close system and be kept in a dry, dark place without any light exposure.
