Our Advantages:

China currently plays a very important role in the world market for plastic additives, with 168, 1010, DSTDP, DLTDP, 977 and 365 being the most produced products in the world.
The price of plastic additives varies significantly with oil, while the cost correlation between antioxidants and palm oil is high.
Since 2020, the number of black swan events in the world has increased, resulting in dramatic changes in raw material prices.
Companies such as UPP, SONGWON, PMC, LG, etc. have been alerted by us in time and have avoided many losses.

We have a 20+ year track record of working with suppliers in China and rating reports on them, and we keep our suppliers updated with the latest news so our customers can get the latest supplier reports.

Specifically, it has excellent features such as no odor, no pollution, non-irritating, and it can be used as a reinforcing agent and emulsifier for waterproofing agents and nail polish and is also more suitable for irregular-shaped items.

UV-531 can be applied to many fields, such as PP, PE, PP/PE, bag and film manufacturing; rubber and plastics recycling processing; leather and shoes manufacturing; printing and dyeing; oil and gas production drilling; and pesticide and chemical manufacture.

Applications:

SUNSORB® 531 works effectively as an antistatic agent, anti-oxidant, anti-yellowing agent, and UV light stabilizer. 

SUNSORB® 531 can be applied in both coating and printing ink as an anti-oxidant and anti-yellowing agent, as well as a UV light stabilizer.

SUNSORB® 531 is a kind of water-dispersible organic UV stabilizer, which is widely used in the polymerization field. It is highly effective for crosslinking and distributing polyvinyl chloride(PVC) and has good compatibility with the polymer. UV-531 can suppress yellowing and fading and inhibit the degradation of color and mechanical properties under sunlight and the influence of the ozone. 

 It is an oil-soluble antistatic agent produced by adding an ultraviolet absorber UV-531 to isopropyl alcohol, acetone, ethyl acetate, or toluene. It has good antistatic performance, low volatility, good stability, etc.
