N，N’－m－phenylene bismaleimide

N，N’－m－phenylene bismaleimide

Abbreviated: PDM or HVA - 2. (BMI-3000)
CAS No. : 3006-93-7
Formula:C14H8N2O4
Molecular weight: 268

Usage: Also called PDM or HVA - 2, multi-functional rubber additives, can be used in the process of rubber processing as vulcanizing agent, also can make peroxide system helps the vulcanizing agent, can make antiscorching agent and tackifier, applies to general-purpose rubber, also applies to special r-ubber and rubber and system.Cooperate with sulfur in natural rubber, can prevent sulfide to return th-e original and improved heat resistance, reduce the heat generated, ageing resistance. Improve rubber and cord adhesion force and sulfide film. Used in truck tire shoulder gum, rubber cushion layer. It can solve the problem of oblique load tire shoulder empty.It can also be used for large size thick product-s of natural rubber,In chloroprene rubber, chlorosulfonated polyethylene rubber, styrene-butadiene rubb-er, nitrile rubber, isoprene rubber, butyl rubber ,brominated butyl rubber, acrylate rubber, silicone rubbe-r and rubber and rubber and other special rubber, as auxiliary vulcanizing agent, crosslinking performa-nce can be improved significantly, improve the heat resistance, is suitable for the high temperature flui-dization system. Reduce the compression permanent deformation is very obvious. It can reduce the do-sage of peroxide, can prevent the rubber scorch in the process, improve and rubber tire cord and m-etal bonding strength.
