Antioxidants For PVC Plastic
Phenyl Diisooctyl Phosphite (PDOP) is a colorless transparent liquid with, a slightly alcohol-like odor, insoluble in water, free phenol is easily hydrolyzed when exposed to moisture, and soluble in organic solvents such as benzene and alcohol.
Production of Phosphite
Changsheng introduced the production line of Phenyl Diisooctyl Phosphite (PDOP) in 2007, and now the annual output is stable at 4000-5000 tons.
We have a large inventory and can deliver in a short time.
R&D of Phosphite
The development of phosphite is complementary to methyl tin stabilizer, and the experiments and tests are done by an identical team. Prosperity always produces according to high requirements and standards to ensure the quality of each batch of goods.

Antioxidants For PVC: Phenyl Diisooctyl Phosphite (PDOP)
Alias: Bis(2-Ethylhexyl) phenyl phosphite/Diisooctyl phenyl phosphate
It is a correspondingly efficient auxiliary heat stabilizer that can improve the color and processing heat stability of polymers during use in high blending, extrusion, calendering, blown film, and other fields.
Phosphite is an auxiliary antioxidant, which plays an important role in the antioxidant system. It has an outstanding ability to decompose hydroperoxides and also has good color protection ability.
