According to the curing conditions, it can be divided into three types: cold curing, room temperature curing and hot curing. Cold vulcanization can be used for the vulcanization of thin film produc......
2019-12-04It can be divided into four stages, each with its own characteristics. It can be seen from the measurement of the fixed tensile strength of the rubber (or the vulcanizer) that the entire vulcanization......
2019-12-04Vulcanization accelerator is a kind of auxiliary agent that can accelerate the vulcanization reaction speed, shorten the vulcanization time, lower the vulcanization temperature, reduce the amount of v......
2019-12-04Dimethyl silicone rubber does not contain vinyl in its molecule and is a saturated rubber. Generally, highly reactive peroxides are used as vulcanizing agents. The peroxide radicals take hydrogen from......
2019-12-04① Dosage of curing agent. The larger the amount, the faster the vulcanization speed, and the higher the degree of vulcanization that can be achieved. The solubility of vulcanizing agents in silicone r......
2019-12-04Mixing is the process of mixing raw rubber or plastic raw rubber with compounding agents into a compound rubber with a rubber mixer. It is the most important production process for rubber processing. ......

2019-12-03Improve the physical and mechanical properties of rubber products. The selection of vulcanization pressure needs to consider the following factors: 1) the formula of the rubber; 2) the plasticity of......
2019-12-03The vulcanization pressure refers to the pressure on the unit area of the rubber compound during vulcanization. Generally, with the exception of some fabric clamps and sponge rubber, other rubber prod......
2019-12-03According to the requirements of different properties of the final product, different vulcanization systems are used in the rubber formulation. Different curing systems have different curing character......
2019-12-03With the increase of room temperature vulcanizate and the emergence of high temperature vulcanization, the vulcanization temperature tends to two extremes. From the viewpoint of improving the curing e......
2019-12-03Rubber vulcanization temperature is one of the three major factors of vulcanization. It is the basic condition for rubber to undergo a vulcanization reaction (crosslinking reaction) and directly affec......
2019-12-03The electrical insulation properties of silicone rubber vulcanizates change little when damp, frequency change or temperature rise, and the silicon dioxide produced after combustion is still an i......
2019-12-02The properties of silicone rubber vulcanizate did not change significantly after being exposed to the sun for several years in a free state.......
2019-12-02Among all the rubbers, silicone rubber has the widest working temperature range (-100-350 C). For example, vinyl silicone rubber or low-phenyl silicone rubber can remain elastic after agin......
