Silicone products, silicone products factory, silicone seals, silicone gaskets, silicone seals are produced using American Dow Corning, German Wacker, Japan Toshiba, Japan Shin-Etsu and other brand materials. Silicone products, silicone gaskets, silicone gaskets, and silicone seals are physically based on a kind of silicon from quartz. To produce this grade of synthetic elastomer, huge organic pendant groups, pendant organic groups, such as methyl, phenyl, and vinyl must be attached to silicon atoms. Add different side chains to achieve different important properties.
Silicone products, silicone seals, silicone gaskets, silicone seals have excellent heat resistance, ozone resistance and corona resistance properties, and its electrolyte stability is very good, in addition to lubricating oil, chemical resistance and resistance The nature of the solvent.
A. The raw materials of silica gel are generally gel-like, somewhat similar to plasticine, colorless, translucent, and tasteless.
B. Its main feature is high temperature resistance (300℃) and low temperature resistance (low -100℃). 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 is chemically inert. Big. The disadvantage is that the mechanical strength is low, oil resistance, solvent resistance, acid and alkali resistance are poor, it is difficult to vulcanize, and the price is more expensive. Operating temperature: -60℃-＋200℃. The above is the description of silicone rubber in the manual.
C. Operating temperature: As mentioned above, it is generally set at -40°C to 200°C, and can reach 230°C in a short time.
D. Aging problem:
Oil resistance, acid and alkali resistance are poor, and it has little to do with the stress.
E. Bonding problem: Before surface treatment, in addition to using silica gel products as adhesives to bond with silica gel parts, the adhesion with other parts must be surface activated, and the rubber surface can be vulcanized before it can be adhered firmly. Any substance that can react with rubber or cross-link it is collectively referred to as a vulcanizing agent, also known as a cross-linking agent. There are many types of vulcanizing agents, and they are increasing. The vulcanizing agents that have been used include sulfur, selenium, tellurium, sulfur-containing compounds, metal oxides, peroxides, resins, quinones, and amines.
F. Material hardness: According to Shore hardness, it can be selected between 10 degrees and 80 degrees in theory. The ones that can be easily found are generally between 20 degrees and 70 degrees, and the commonly used ones are between 50 and 60 degrees.
The operating temperature of silicone products, silicone sealing rings, silicone gaskets, and silicone seals
is -60 to 225 degrees. Some special types can reach a high temperature of 315 degrees.
Customize the shape, hardness, size and color according to customer drawings
Silicone products, silicone seals, silicone gaskets, silicone seals are used in automobiles, electronics,
electrical appliances, home appliances, machinery, daily necessities and aviation.
