FAQ
Q: What are the main uses of triphenyl phosphite (TPP)?
A: It is an auxiliary antioxidant, a heat stabilizer, and a PVC complexing agent (phosphite type).
Q: What are the regular product specifications?
A: The industrial mainstream purity is ≥ 98%; the freezing point, refractive index, chloride ions, moisture, and color can be controlled; a COA test report is provided with the goods.
Q: How is its solubility?
A: It is insoluble in water; it is easily soluble in organic solvents such as benzene, toluene, ether, acetone, and chloroform; it will slowly hydrolyze upon contact with water and moisture, releasing phenol.
Q: What are the storage conditions and shelf life?
A: Store in a sealed, dry, cool warehouse, strictly prevent moisture, away from strong acids, strong bases, and oxidants. It will hydrolyze upon moisture absorption, increasing the acidity of the product, which will affect the stability of the downstream. The original packaging is sealed and has a shelf life of 24 months. Below 22℃, the product will solidify; after heating and melting, the performance will not be affected; do not forcibly pump before melting.
Q: What is the recommended packaging method? MOQ & Delivery time?
A: 200kg galvanized iron drums; 1000kg IBC tanker drums. MOQ: 200kg; Delivery time: 3-7 days for small orders, and large orders can be scheduled for production.
