Features: It shows excellent antioxidantion as well as pump-transport convenience. With low volatility and outstanding compatibility it shows especially good effect during the process of forced air cooling of PU.This function can also prevent surface fogging of auto parts and fabric’s coloring (e.g.: furniture,carpet etc_.The low volatility and liquid state maek it especially suitable under the condition of liquid,latex suspension,solution or melting polymerization and processing .It can be added before, in the middle of or after polymerization.

Applications: It is an excellent antioxidant for various polymers. For PU soft-foam rubber plate it can prevent polybasice alcohol from creating peroxide during storage period and prevent scorch during the process of froth. Used in lubricant oil,it could improve the thermal stability.

Recommended Dosage:0.15-0.5%
