2,2,4-Trimethyl-1,2-dihydroquinoline, polymerized
26780-96-1
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.
DQ-H 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.
Antioxidant DQ-H is extremely effective in protecting rubber products based on natural rubber, polyisoprene, SBR, EPR/EPDM, NBR and polybutadiene against oxygen and heat simultaneously.
It is less suitable for polychloroprene but has a moderately strong antiozonant effect.
In natural rubber, it has some anti-flexcracking properties.
Antioxidant DQ-H is non-blooming but does cause discoloration and staining.
Increasing amounts in polymers do slightly decrease viscosity.
Increasing amounts also improve scorch resistance but increase cure time.
