4. Properties:


HVA-2 combined with Sulfur used in natural rubber, can prevent reversion, improve heat resistance, lower heating rubber. It can be as vulcanizing agent, also can be as peroxide additives agent. HVA-2 used as vulcanizator or auxilliary vulcanizator for various kinds of synthetic rubber, can significantly improve the heat-resistance and cross-linking. HVA-2 can also significantly reduce rubber compression, improve the metal rubber and cord adhesion strength, prevent rubber scorching in the process. HVA-2 not only applicable to regular rubber parts, can also be applied to large tires and special big specification rubber parts. HVA-2 is a sulphur-free vulcanization agent, can be used for rubber cable, can be substitute of thiazole, thiuram all sulfur vulcanization agent, can solve the copper wires and copper electric appliances, due to exposure to sulfur vulcanizing agent generated black copper sulfide pollution problems. 

5. Dosage: 


0.5-1.0phr as a scorch retarders; 2-3phr if as a vulcanizator; 1.5phr as to improve compression deformation; 0.5-5.0phr as for improving bonding strength
