Specialty Materials

Specialty materials are used in specialized or proprietary applications. Specialty materials are high performance metals which are widely used. There are several types of specialty materials. Examples include plastic material, electrical material, metalloids, thermal, interface material, thermal compound, semiconductor material, raw plastic material, thermal insulation material, electrical insulation material, thermoplastic material, metal nonmetals and metalloids, optical material, and thin film material. Raw plastic material is used to form plastic material that is classified into two types: thermoplastic and thermosetting plastics. Thermoplastic material is the linear non-crossed plastics that melt at temperatures above 180° F and when cooled it sets into a shape. Metal nonmetals and metalloids are important materials that differ because of their features. Metalloids combine features of both the metals and nonmetals. Thermal insulation material is used to retain heat inside a particular area and stops it from escaping. Electrical insulation material is used for substrate of flexible PCB and wrapping the magnet cable and wire. Thin film material is used in many technology applications like magnetic storage, surface coating and microelectronic devices. Other types of specialty materials are commonly available.

Specialty materials are manufactured in a variety of ways and each one serves a different purpose. Specialty materials can be produced from stainless steel, titanium, tool steel, and high temperature alloys that are high performance metals. Specialty materials are utilized in electric machines and apparatus and can also be used in automatic and remote control equipment. Plastic material is prepared from resins, either natural or synthetic, and with or without fillers. Raw plastic material forms include the sheet, powder or liquid resins, sheet or bulk molding compounds (SMC / BMC), pellets and plastic resin, and resin compounds. Thermoplastic material is more elastic, less brittle and does not lose its elasticity when subjected to prolonged heating. Metals are malleable and ductile, and they exist in solid form at room temperature. Nonmetals are poor conductors of electricity and heat and there melting point is lower than metals. Commonly known metalloids are silicon, arsenic, antimony, polonium and boron. Electrical material has high conductivity and resistance to corrosion. When an electrical material is used for contact, it provides low contact resistance. Thermal interface material and thermal compound materials forms a thermally conductive layer either between the components or within finished product on the substrate. The specifications of Thermal interface material and Thermal compound materials include thermal, electrical, mechanical, processing and physical properties. Thermal properties include thermal conductivity, service temperature while the electrical properties include dielectric strength, electrical resistivity and relative permittivity. Thermal interface material and thermal compound material are mainly used to join the components. They use many chemical systems such as epoxy resin, polyvinyl chloride (PVC), polybutadiene. An important specialty material is semiconductor material. The most common type of semiconductor material is silicon, germanium and gallium. There are two types of insulation materials: electrical insulation material and thermal insulation material. Thermal insulation material acts as a barrier to minimize transfer of heat energy from one of the material to other material and less dense materials form better insulators. Electrical insulation material includes a polymide film that is formed by polymerizing ODA and PMDA by the process of forming film at high temperatures. Optical material is available in various types like GeAsSe that has refractive index of 2.5, wavelength in range 0.9-11. Optical material includes sapphire, calcite, and quartz. Thin film material is a high purity material and precursor gases, evaporation filaments are the chemicals that are used to modify thin film deposit. Specialty materials are designed and manufactured to meet most industry specifications.

Specialty materials are widely used in industries for manufacturing electronic components and the semiconductors. Specialty materials are also used in mechanical lines to provide electrical insulation of appliance lines. Specialty materials are utilized in relays, switches, and circuit breakers.
