There are as many varieties of cable insulation material  wire and cable insulation as there are wires and cables. Insulation is an important non-conductive material that surrounds and protects the individual wires or cables that make up a cable assembly. Some wire insulation is produced to resist electric current in electrical applications. Other types of insulation are used in dielectric applications for radio frequency cables. Insulation further prevents current from contact with other conductors, resists electrical leakage and offers protection from all environmental conditions. Depending on the application, insulation generally is from plastic, fluoropolymers or rubber materials.With a temperature range between -55°C and 105°C, it is flame, moisture, and abrasion resistant.

Its applications are compatible with gasoline, ozone, acids, and solvents, and it is safe for medical and food related purposes as it is odorless, tasteless, and non-toxic. Applications are suited for interiors in spaces beneath raised floors of above dropped ceilings or raised floors, primarily areas with air circulation.Though flammable, it carries exemplary electric qualities, can reduce the dielectric constant, and is a very good option for cables requiring high-speed transmission. With cross-linking, polyethylene properties can produce high resistance to cracking, cut-through, soldering, and solvents. Its temperature range is.Rubber refers to both natural rubber  and synthetic SBR compounds.

Though this material has poor oil and ozone resistance, it has good low-temperature flexibility, offers good water and alcohol resistance, electrical properties and excellent abrasion resistance.Neoprene has a long service life, wide temperature range, is flame retardant and self-extinguishing.Silicone is a versatile synthetic rubber known for its high heat-resistant and flame-retardant properties. It is extremely flexible with average abrasion-resistance, and is ideal with many electrical applications.Fiberglass is the most widely used glass insulation.

With continuous working temperatures up to 482°C, the material has very good moisture and chemical resistance, but low abrasion resistance. It’s commonly used in applications for heat treating, glass and ceramic kilns, foundries and aluminum processing.Ethylene Propylene Rubber  has excellent thermal and electrical properties, and is commonly used in high-voltage cables. The material is soft and flexible, and offers very good resistance to heat, oxidation, weathering, water, acid, alcohol and alkali. It also has an operating temperature range of . Due to its softness and flexibility, it should be handled with care during installation.
