Silicone material characteristics
A. Silicone raw materials are generally gel-like, somewhat similar to plasticine, colorless and translucent, and tasteless.

B. Its main characteristics are both high temperature resistance (300 ° C) and low temperature resistance (low -100 ° C). It is currently cold and high temperature resistant rubber. At the same time, it has excellent electrical insulation, high stability to thermal oxidation and ozone, and chemical inertness Big. Disadvantages are low mechanical strength, poor resistance to oil, solvents, and acids and alkalis, harder vulcanization, and higher prices. Operating temperature: -60 ℃-+ 200 ℃. The above is the description of silicone rubber in the manual.

C. Operating temperature: As described above, it is generally set to -40 ℃ -200 ℃, and can reach 230 ℃ in short time.

D. Aging problem: Poor oil resistance, acid and alkali resistance, and little to do with stress.

E. Adhesion: Before the surface treatment, in addition to the use of silicone products as adhesives and silicone parts, all other parts must be surface activated, and the adhesive surface can be cured by vulcanization. Any substance that can vulcanize or crosslink with rubber is collectively called a vulcanizing agent, also known as a crosslinking agent. There are many types of vulcanizing agents, and they are constantly increasing. Sulfurizing agents that have been used include sulfur, selenium, tellurium, sulfur compounds, metal oxides, peroxides, resins, quinones and amines.

F. Material hardness: According to the Shore hardness, plastic parts can be theoretically selected between 10 degrees and 80 degrees in the domestic market. It can be easily found at 20 degrees to 70 degrees, and usually 40 to 50 degrees.
