There are two types of antioxidants, one is chemical synthesized and the other is natural antioxidants. Chemical synthesis, such as BHT, BHQ, TBHQ, ethoxyquinoline, PE, etc., these are considered to be called chemical synthesis of antioxidants, these antioxidants have been banned in Europe, that in China and the United States, is the amount of additive per kilogram can not be greater than 0.2, these chemical synthesis of antioxidants, it is true that there is now some controversy, but the antioxidant effect is relatively good.

The unsaturated resin polymerization inhibitor MTBHQ (2-tert-butylhydroquinone) plays an important role in resin synthesis and other synthetic reactions. The following is a detailed analysis of its principle of action and effects:Effect Remarkable polymerization inhibition effect: MTBHQ is a kind of high efficient polymerization inhibitor for unsaturated resin. Under normal storage conditions, the general addition amount is only two ten-thousandths of the total amount of resin, and it can play a good effect of polymerization inhibition.
