In natural rubber, with sulfur yellow, can prevent the vulcanization back to the original, improve heat resistance, reduce heat, anti-aging, improve rubber and cord adhesion and vulcanized rubber modulus. Used for loading tire shoulder gum, cushion layer and other rubber, can solve the bias truck tire shoulder problem, can also be used for large-scale natural rubber products and all kinds of rubber sundry goods.
For example: With sulphur yellow, promoter Mpmcz or TMTD this initiator, vulcanized diene rubber (natural rubber, butyl benzene gum, NBR gum, synthetic isoprene rubber) has the time to prolong the burnt burning, reducing calorific value, high tensile strength, good resistance to the original properties, but also can increase H extraction, applicable to rubber high-temperature vulcanization (183 ℃), the dosage of 2-3phr, suitable for large tires and thickening, increase products.
As a vulcanizing accelerator of chloroprene rubber, it can obviously improve the coke-burning performance of the mixed rubber, and is suitable for the processing of chloroprene rubber in the South high temperature season.
As a variety of rubber peroxide vulcanizing agent, especially in the butyl clear gum, EPDM and rubber and the peroxide vulcanization process in the body, can play a low compression deformation, fast vulcanization and heat-resistant air aging of the compound.
For example, in NBR, when the dosage is 1.5PHR, the permanent compression deformation is only $number, the use of other vulcanizing agents can not be achieved.
In neoprene, sulfonated polyethylene rubber, styrene butadiene rubber, NBR, isoprene rubber, butyl rubbers, brominated butyl rubber, acrylate rubber, silicon rubber and rubber and other special rubber, as an auxiliary vulcanizing agent, can significantly improve the association performance, improve heat resistance, suitable for high-temperature vulcanization system, reduce the compression of permanent deformation is very obvious, but also reduce the amount of peroxide, to prevent the rubber material in the process of burning, improve the rubber and curtain line and metal bonding strength.
When used for sulfonated polyethylene rubber, it can be used as a coke-proof agent with magnesium oxide, pentaerythritol and double five times methyl sulfide (TRA).
Improve compression deformation
With the combination of calcium hydroxide and two phenyl ethylenediamine to form a maleic imide vulcanization system, the dosage is 2-4phr, which can greatly reduce the compression permanent deformation and improve the temperature-resistance performance.
Increase bonding strength
Improve rubber and polyamide fabric, rubber and metal bonding strength, applicable to the direct bonding system.
The product is a sulfur-free vulcanizing agent, used in cable rubber, it can replace the thiazole, Autumn lamb, such as all sulfur-containing vulcanizing agent, to solve the copper wire and copper appliances due to contact with sulfur sulfide to produce copper sulfide pollution black problem.
Used as anti-Coke agent: 0. $number. 0phr as vulcanizing agent: 2-3PHR
To improve the compression deformation: 1.5phr to improve adhesion strength: 0.5-5.0phr
