Audited Supplier Vulcanizing agent series -- m-phenyl-bismaleimide (HVA-2 or PDM)
CAS No:3006-93-7
Molecular formula:C14H8N2PO4
Molecular weight:268
Product Description:
Physical and chemical properties: yellow or brown-yellow powder, specific gravity :1.44, soluble in dioxycontinental ring, tetrahydroflavan and hot acetone, insoluble in petroleum bond, dichloromethane, carbon tetrachloride, benzene and water.
Use :PDM or HVA-2 is a multi-functional rubber auxiliary agent, which can be used as a vulcanizing agent in the rubber processing process, and can also be used as a co-vulcanizing agent in the peroxide system, and can also be used as an anti-coke agent and viscosifier, which is suitable for general rubber, but also suitable for special rubber and rubber combined system.
In natural rubber, with sulfur, can prevent vulcanization return, improve heat resistance, reduce heat generation, aging resistance, improve rubber and cord adhesion and vulcanization modulus.Used for truck tire shoulder rubber, can solve the problem of bias truck tire shoulder empty, can also be used for natural rubber large size thick products and various rubber miscellaneous products.
In the special rubber such as neoprene rubber, chloro-sulfonated polyethylene rubber, styrene butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, brominated butyl rubber, acrylic rubber, silicone rubber and rubber composite rubber, as an assistant vulcanization agent, it can significantly improve the crosslinking performance and heat resistance, and reduce the compression permanent deformation is very obvious when applied to high temperature vulcanization system. It can also reduce the amount of peroxide, the coking of textile rubber in the process of processing, and improve the bonding strength of rubber and cord and metal.
HVA-2 or PDM is a sulfur-free vulcanizing agent for cable rubber, which can replace thiazole, thiuram and other sulfur-containing vulcanizing agents, solving the problem of copper wire and copper electrical appliances due to contact with sulfur-containing vulcanizing agents to produce copper sulfide pollution black.
