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.
