Product Abstract:

Methyl vinyl silicone rubber because of the increase in vulcanization activity of heat resistance and high temperature compression deformation resistance is a great improvement, is the largest and the most widely used type of silicone rubber production, varieties brand is also the most. In addition to general-purpose rubber, all kinds of specificity and processing characteristics of silicon rubber, they are all based on its process, such as high strength, low compression deformation, conductivity, afterburning, thermal conductivity of silicone rubber, etc. This kind of silicone rubber is widely used in type O sealing ring, oil seal, all kinds of pipe, sealants and adhesives, etc.


Product Description

Methyl vinyl silicone rubber [1], also known as methyl vinyl silicone rubber, its full name is poly (methyl vinyl silicone rubber (Polymethyl vinyl siloxane rubber), code-named MVQ, department of dimethyl silicone rubber on the side chain of introducing a small amount of vinyl. Introduction of vinyl improved the shortcoming of dimethyl silicone rubber, silicone rubber can be improved vulcanization activity, can use less active organic peroxide vulcanization crosslinking, and can reduce the dosage. Improves the performance of the vulcanizates improved at the same time, such as increasing the product hardness, lower compression deformation, thick products sulfide are more uniform, and reduce the bubble. Generally considered vinyl content in 0.07 ~ 0.15% (mol) silicone rubber has good comprehensive performance. Increase the content of vinyl curing rate can be improved, and available sulfur vulcanization accelerator, but the thermal stability of the drop, the physical properties of vulcanized rubber is also low.
