1. Silicone rubber, bicomponent RTV
Type: RTV-106、RTV-107、RTV-133、RTV-135、RTV-141、RTV-143
Packaging: rectangular or plastic drum
Applications: room temperature vulcanized silicone rubber is mainly used as a moisture-proof, shock-proof, heat-resistant, insulating material and for electrical elements and instruments.
Characteristics: this is a kind of elastomer vulcanized under room temperature, which is based on hydroxyl terminated poly two organic siloxane and cross-linked by polyfunctional silane or siloxane; excellent electrical insulation properties, resistance to arc, corona, water, ozone, and weather aging; high and low temperature performances that are very good and can be used within a temperature range of -60~+200 C.
2. Silicone rubber, single component RTV
Type: GD414、GD407、GD406、GD405、GD404、GDZ-421、GD402、GD401
Packaging: tube
Applications: mainly used in producing painting material for electronic components and electrical instruments for insulation, and moisture-proofing and shock-proofing; also for surface protection materials, sealants, filling materials, and elastic adhesive for semiconductors (engine cylinder sleeves, temporary sealant or binder for pipes or instruments, molded in situ).
Characteristics: made of liquid telechelic prepolymer (third molecular chain consists of dimethyl chain, with two active groups at the end.), with filler and auxiliaries; packed in a tube and, after being extruded and exposed to air, can auto-vulcanize to form elastomer, for convenience; this sulfide can be used over a long period of time within a temperature range of -50~+200 C and has good electrical insulation and chemical stability; it is water-, ozone-, and weather-aging-resistant, with good adhesion to metal and nonmetal materials.
3. Silica gel
Type: GN581、GN522、GN512、GN511、GN502、GN501
Packaging: bottle
Application: this gel can be used as Ceramics, adhesive and paint material for moisture-proofing, insulation and shock-proofing; can also be used as inner protective coating, adhesive heating sheet, low-temperature packaging element, or local heat sealing material for semiconductor devices; with silver powder, it can be used as conductive adhesive. GN502 and GN501 are mainly applied to general ceramic material. GN512 andGN511 can be mixed with other materials and can be used as packaging material for electronic components.
Characteristics: colorless, or light yellow, transparent liquid before vulcanization; packed separately by M and N; when mixed in correct proportions, M and N can vulcanize to form transparent elastomer under certain temperatures; gel viscosity is low before vulcanization, making it convenient for ceramics; during vulcanization, no heat or low molecular compound is generated, and there is low shrinkage and no corrosion; vulcanized rubber can be used over a long period of time within a temperature range of -60~+180 C; moisture-, water-, ozone-, radiation-, and weather-proof; has good electrical and mechanical properties, and chemical stability.
