ADVANTAGES -
*Very strong UV absorptivity in the ultraviolet region (especially in 300～400nm).
*Very low vapor pressure,prevents product from loss during processing.
*No effect on the odor of the resins.
*Very good compatibility with thermoplastic polymers owing to its octoxy substituent group,thus ensuring homogeneous distribution during processing.
*High purity,no adverse effects due to impurities.
*Very high heat resistance,without significant degradation or volatility at proper extrusion temperature.
APPLICATIONS -
|
1.POLYPROPYLENE(PP)
2.POLYETHYLENE(PE)
3.POLYVINYL CHLORIDE(PVC)
|
Recommended level:0.2～0.5% on the polymer weight.
