Uses

Being a kind of multifunctional rubber additive HVA-2 could be used as vulcanizing agent in regular rubbers, act as the cocuring agent for peroxide system. It is also coud be act as antiscorching agent or tacktying agent. Cooperating with sulfur in nature rubber HVA-2 could prevent reversing, improving rubber's resistance to thermal, reducing pyrogenesis,increase the bond force between rubber and cord. It could desolve the shoulder's seperation effectively when HVA-2 applicated in lorry tires's shoulder or buffering layer.When used as cocuring agent in Chlorosulfonated polyethylene rubber(CR), styrene- butadiene rubber(SBR), Nitrile rubber(NBR), isoprene rubber (IR), Butyl rubber(|IR), Bromobutyl rubber, acrylic rubber(ACM), Silicon rubber(SI) and other rubbers, HVA-2 can improve the polymer's correlation pertormance and heat resistance effectively. HVA-2 could be applicated in the high-temperature
vulcanization system and reducing permanent set effectively ,save the peroxide agen's dosa preventing scorching during the vulcanizing process, improving the bond force between rubl
frame.As a non-sulfur vulcanizing agent when used in cable polymers, HVA-2 can substitute Vulcanizing agentsuch as thiazole type, thiuram and other, hich solve the blackening which copper's pollution.

Dosage

0.5-10 portion when used as antiscorching agent, 2-3 portion when used as vulcanizing agent, 1.5 portion when used as compression deformation improving agent, 0.5-5.0 portion when used as adhesion strength improving agent.
