Antioxidant DQ-H is a 2,2,4-trimethyl-1,2-dihydroquinoline, polymerized.
It is particularly useful in polymers requiring resistance to high temperatures.
Antioxidant DQ-H is higher in melt point than Antioxidant DQ.
DQH is used when extreme temperature conditions are encountered.
Applications include wire and cable type processing as well as providing protection for crosslinked polyethylene.
It can also be used as a copper and manganese inhibitor. |
