N,N'-1,3-Phenylene bismaleimide Applications
N,N'-1,3-Phenylene bismaleimide (Vulcanizing Agent PDM) is a multifunctional rubber additive that can be used as a vulcanizing agent, a co-vulcanizing agent in peroxide systems, and a scorch retarder and tackifier during rubber processing. It is suitable for general-purpose rubber, specialty rubber, and rubber-plastic systems.
In natural rubber, when combined with sulfur, it prevents reversion, improves heat resistance, reduces heat buildup, enhances aging resistance, and enhances rubber-cord adhesion and vulcanized rubber modulus.
N,N'-1,3-Phenylene bismaleimide (Vulcanizing Agent PDM) is used in tire shoulder rubber, breaker layers, and other rubber components, addressing the shoulder void problem in bias truck tires. It can also be used in large-sized, thick natural rubber products and various miscellaneous rubber products.
PDM, as a co-vulcanizing agent in specialty rubbers such as chloroprene rubber, chlorosulfonated polyethylene rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, butyl rubber, bromobutyl rubber, acrylic rubber, silicone rubber, and rubber-plastic blends, significantly improves crosslinking properties and heat resistance. It is suitable for high-temperature vulcanization systems and significantly reduces compression set. It also reduces peroxide usage, prevents scorching during processing, and improves the bond strength between the rubber and cord and metal.
PDM is a sulfur-free vulcanizing agent used in cable rubber. It can replace all sulfur-containing vulcanizing agents, such as thiazoles and thiurams, solving the problem of copper conductors and electrical appliances becoming contaminated and blackened by copper sulfide formed by contact with sulfur-containing vulcanizing agents.
N,N'-1,3-Phenylene bismaleimide (Vulcanizing Agent PDM) Dosage: 0.5-1.0 phr as a scorch retarder, 2-3 phr as a vulcanizing agent, 1.5 phr for improving compression set, and 0.5-5.0 phr for improving bond strength.
