Ceramic and glass have long functioned as the material of choice for medium and high-voltage electrical applications, high-voltage insulators and lightning arresters. These materials have good resistance to electrical stress as well as outdoor exposure without suffering significantly from deterioration. The transmission/distribution industry and international standard bodies have thoroughly discussed the advantages and disadvantages of these materials. Their shortcomings include contamination and the inability to handle certain stresses. These concerns have led to significant innovations in material science, especially as it relates to insulative materials and silicone rubber’s electrical conductivity.
Multiple scanning rates were used to gain insight into the effect of time and temperature on the curing reaction of LSR and HCR systems. Properties of peak temperature, heat of reaction, and extent of reaction are obtained.
The compression and transfer molding process, using plastic and high consistency rubber (HCR) as raw materials, was once the dominant manufacturing process in medical, aerospace, electrical, construction and industrial applications. In recent years, however, Liquid Silicone Rubber (LSR) 2-Shot injection molding has been the manufacturing process of choice across a range of industries for the fabrication of molded parts. The LSR 2-Shot molding process enables manufacturers to produce parts in a wide range of sizes and technical configurations, one of the many advantages 2-Shot injection molding has over compression and extrusion molding.
Liquid Silicone Rubber exhibits many useful characteristics. They are resistant to the environment are permeable to gas and vapor and can be colored as needed.
Silicone rubbers exhibit many useful characteristics. The electrical properties are, in general, superior to those of organic rubbers, and the conductivity can be customized using special additives.
