End-chain vinyl silicone oils (such as end-vinyl polydimethylsiloxane) have shown unique application advantages in many fields due to the high reactivity of vinyl at both ends of the molecular chain. Their application scenarios can be summarized as the following core directions： 1. Silicone rubber field: preparation of high elasticity and high strength materials High temperature vulcanized s

The application difference between end-chain vinyl silicone oil and straight-chain vinyl silicone oil is mainly reflected in the difference in reactivity and application scenarios caused by the molecular structure. The former is mostly used for high elasticity and high strength silicone rubber due to the high activity of vinyl at both ends; the latter is mostly used for liquid silicone rubber and

When the vinyl content in silicone rubber is too low, it will have a significant impact on its vulcanization properties, mechanical properties, processing properties and final application. The specific performance and countermeasures are as follows： 1. The impact of low vinyl content Decreased vulcanization performance Insufficient crosslinking: Vinyl is the active crosslinking point in the

When mixing silicone rubber with different vinyl content, the overall performance of vinyl molar fraction in the range of 0.10% to 0.25% is excellent, and key properties such as tear strength can be significantly improved through reasonable proportions.The specific analysis is as follows： Performance optimization mechanism Centralized crosslinking structure: When silicone rubber with high vi

Silicone rubber with different vinyl content can be mixed and used, and the overall performance can be significantly improved through a reasonable ratio.As the active crosslinking point in the molecular chain of silicone rubber, vinyl directly affects the crosslinking density and mechanical properties of vulcanized rubber.When silicone rubber with high vinyl content and low vinyl content is mixed,

Methyl vinyl silicone rubber has been widely used in many fields due to its excellent high and low temperature resistance, thermal stability, electrical properties and chemical stability. The specific uses are as follows： 1. Aviation industry Sealing and protection: As gaskets and sealing materials, they are used for sealing key parts such as aircraft fuel systems and hydraulic systems to pr

There are significant differences between methyl silicone rubber (dimethyl silicone rubber) and methyl vinyl silicone rubber (MVQ) in molecular structure, vulcanization properties, application areas and process characteristics. The specific analysis is as follows： 1. Molecular structure differences Methyl silicone rubber: The main chain is composed of a silicon-oxygen bond (Si-O), and the si

Reinforcing fillers not only significantly improve the mechanical strength in silicone rubber, but also improve the overall performance of the material through a variety of mechanisms. The specific effects are as follows： 1. Improve processing performance Rheological regulation: The nanoscale particles of reinforcing fillers (such as fumed silica) can form a three-dimensional network structu

After adding a reinforcing filler, the strength of silicone rubber can be increased by about 40 times, the specific performance is that the tensile strength of vulcanized rubber is increased from 0.35MPa of pure silicone rubber to 14Mpa.This reinforcing effect is significantly better than that of other rubber materials (usually the reinforcing rate is 1.4-10 times), reflecting the decisive role of

The process of converting silicone oil into silicone rubber is a complex process involving chemical synthesis and physical processing. Its core lies in the conversion of liquid silicone oil into a solid elastomer with a three-dimensional mesh structure through a specific chemical reaction.The following is a detailed analysis of this process： 1.
