Diphenyl phosphite/CAS 4712-55-4/DPP
25 kg/drum or 200 kg /drum or based on customer's requirements.
DIPHENYL PHOSPHITE is a high phosphorus content and high activity diarylphosphate antioxidant, which can be widely used in polyolefin, resin synthesis, lubricating oil, etc., to improve light resistance and color stability.
Used for the synthesis of unsaturated polyester resin, it can effectively improve the color of the synthesized resin.
IPHENYL PHOSPHITE DPP can also be used as a stabilizer for PVC to improve its initial color and has good anti precipitation properties. Using it in lubricating oil can effectively improve the antioxidant and anti-wear properties of the oil.
Suggested addition amount: 0.1~1.0%

To store diphenyl phosphite DPP safely and effectively, consider the following guidelines:
1. Container: Store diphenyl phosphite in airtight containers made of compatible materials, such as glass or certain plastics that are resistant to organic solvents.
2. Temperature: Please store it in a cool and dry place, away from direct sunlight and heat sources. It is best to store it at room temperature, but avoid extreme temperatures.
3. Ventilation: Make sure the storage area is well ventilated to prevent vapor accumulation.
4. Incompatibility: Keep diphenyl phosphite away from strong oxidants, acids and bases as it may react with these substances.
5. Label: Clearly label containers with the chemical name, hazard information, and receipt date.
6. Safety Precautions: Store it in a designated chemical storage area, away from food and drink, and ensure that appropriate safety measures are in place in case of accidental leaks (such as spill emergency response kits and personal protective equipment).


There are some safety issues with diphenyl phosphite that should be considered:
1. Toxicity: Diphenyl phosphite may be harmful if ingested or inhaled. It may irritate the skin, eyes, and respiratory tract. Long-term exposure may cause more serious health effects.
2. Handling: When working with diphenyl phosphite, always use appropriate personal protective equipment (PPE), such as gloves, goggles, and respiratory protection if necessary.
3. Storage: As mentioned before, it should be stored in a cool, dry place, away from incompatible materials, and in well-sealed containers to prevent leakage and exposure.
4. Environmental Impact: Like many chemicals, diphenyl phosphite may have environmental impacts if released into the environment. Appropriate disposal methods should be followed according to local regulations.
