Many companies publish chemical resistance charts. [2] and databases [3] to help chemical users use appropriate materials for handling chemicals. Such charts are particularly important for polymers [4] as they are often not compatible with common chemical reagents; this may even depend on how the polymers have been processed. [5]
Silicones also exhibit good chemical resistance and high-temperature resistance (205 °C, 400 °F and higher). For this reason, silicone molds are suitable for casting low-melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal). RTV silicone rubbers are, however, generally expensive – especially platinum-cure.
Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required.
Bisco industries was founded in Chicago, Illinois by Glen Ceiley on March 15, 1973. At the time, Glen F. Ceiley was the sole employee of Bisco industries and assumed the following roles: purchasing agent, salesperson, shipper, receiver and bookkeeper. Bisco industries is a supplier and distributor of fasteners, hardware, and electronic components.
With the increased use of low-current switching in automobiles, silicone-rubber keypads are being used extensively as switch mechanisms for various buttons such as window lifts and steering wheel mounted controls. Low-resistance pills such as SC pills and gold pills, along with short-stroke metal-dome contacts, are widely used in these settings.
Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
Silicone resin with R = CH 3, H or OH. Silicone resins are a type of silicone material which is formed by branched, cage-like oligosiloxanes with the general formula of R n SiX m O y, where R is a non-reactive substituent, usually methyl (Me = −CH 3) or phenyl (Ph = −C 6 H 5), and X is a functional group: hydrogen (−H), hydroxyl (−OH), chlorine (−Cl) or alkoxy (−O −).
