Why can not be used in the silicone rubber vulcanization?
![]()
At present, most of the silica gel tube is MVQ, and the content of vinyl content in 0.1--5% is about.
The. As EPDM and Q have many similarities, they are non polar rubber, which have the introduction of unsaturated double bond groups, as well as the same.
Good insulation, aging resistance, hydrophobicity, but why EPDM can be used sulfur vulcanization, Q can not it (mature technology)? BI
There are still a lot of advantages of sulfur curing.
Shenzhen odd and silicone rubber manufacturers to share: peroxide curing mechanism is different, peroxide will not stay in the matrix. So high temperature resistance
Can be good. Silicone tube is an inorganic hybrid polymer, and the molecular chain is SI-O-SI, and the main mechanism of the polymer is SI-H. Since
By the base type, so with the peroxide sulfide. With the improvement of the synthesis process, the introduction of vinyl in silica gel molecular chain is mainly to improve its
Vulcanization characteristics, but the content is generally very few. The most important is that the high temperature resistance of the silicone rubber is not lost, even though it can be cured by sulfur.
Out? Sulphur can only be vulcanized by the unsaturated rubber, and no double - built - sulfur can not form a cross-linked structure.
The vinyl content in silicone tube is very small, and the sulfur curing system of the common organic rubber is unable to make it.
Sulphur is generally used to cure unsaturated rubber.
