| Introduction | Antioxidant DSTP is usually white particles or powder, which can give materials excellent long-term thermal stability, it is usually used in combination with a phenolic antioxidant. |
| Use | The antioxidant DSTDP is an antioxidant additive used to prevent degreasing or oxidative decomposition of organic polymers. The antioxidant DSTDP reduces the aging properties of poly (1-Butene) in a hot air aging chamber. It is used as an antioxidant for rubber, soap, grease, lubricating oil, grease, polyolefin, etc. The product is used as an auxiliary antioxidant and phenolic antioxidant, and its anti-oxidative aging productivity is superior to that of dilauric acid with thiodipropionic acid. The product is not colored, no pollution, it is suitable for white and bright color products. used as an auxiliary antioxidant for polypropylene, polyethylene, synthetic rubber and Grease can be widely used in polyethylene, polypropylene and ABS, PBT and other synthetic materials, can also be used in rubber processing and lubricating grease |
| Application | Antioxidant DSTP is suitable for: polyolefins, styrenic homo-and copolymers. |
| addition amount | The addition amount of antioxidant DSTP: 0.05%-1%, the specific addition amount is determined according to the application test. |
| production method | is obtained by the reaction of a decanoate with a thiodipropionic acid. |
