| Type / Form | |||
| Your choices are... | |||
| Adhesive | Adhesives are organic or inorganic chemical compounds for joining components. They require clean surfaces that are compatible with the adhesive. | ||
| Casting Resin / Two-part (A+B) | Casting resins are plastic or elastomer compounds used to cast parts or molds or to form a structure in place. Casting resins usually consist of two part (A+B) systems that are cast into open molds or forms. A multi-component system typically consists of two separate components (A + B) where A is the resin and B is the catalyst or hardener. The user or fabricator mixes the components to start the curing process. Two or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator, or catalyst that, when combined, react and cure into a polymerized compound or bond. Two component systems are mixed and then applied. | ||
| Coating / Paint | Coatings are thin films deposited upon materials to add or enhance desired properties. They provide color, conductivity, corrosion resistance, etc. | ||
| Conduit | An electrical conduit is a system or length of solid tubing used to house, protect, and cover electrical wiring and cables in power distribution systems. | ||
| Enclosure (Electrical / Electronic) | Electrical and electronic enclosures are designed to house electrical and electronic components. | ||
| Encapsulant / Conformal Coating | Encapsulants are compounds used for the sealing or covering of an element or circuit for the purpose of mechanical and environmental protection. Typically, the encapsulant layers are not more than 100 millimeters thick. | ||
| Gasket / Gasketing | Gaskets and gasketing are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces. | ||
| Magnetic Shielding | Magnetic shielding includes products and raw materials for shielding instruments and equipment from magnetic fields. | ||
| Molding Compound | Molding compounds and resins are industrial plastics and polymers that are suitable for forming. They are available as pellets, liquids, and powders and are used in processes such as injection molding, compression molding, reaction injection molding (RIM), resin transfer molding (RTM), and blow molding. | ||
| Sealant / Gap Filling Compound | Gap filling or underfill compounds are used to fill gaps or spaces between two surfaces that are to be bonded or sealed. Flexible sheet materials, as well as sealants or form-in-place compounds (FIP) such as liquid and viscous materials, are used to fill gaps between seams. On surfaces they are used to contain fluids, prevent leaks, and prevent infiltration of unwanted material. | ||
| Stock Shape / Custom Part | Stock shapes of plastics or elastomers are suitable for fabricating parts by machining, assembly, or other processes. | ||
| Tape / Film | Products are specialized tapes for EMI and RFI shielding applications. | ||
| Thermal Compound / Interface | Thermal compounds and thermal interface materials form a thermally conductive layer on a substrate, between components or within a finished product. | ||
| Specialty / Other | Other specialty, proprietary, or unlisted organic or inorganic technologies or cure types for adhesive or sealant-related applications. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Electrically Conductive? | Resins or compounds have a high degree of electrical conductivity (low resistivity) for applications such as anti-static or ESD control, EMI / RFI shielding, thick-film metallization, and device and board electrical interconnection. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Anti-static / ESD Control? | Materials are designed with relatively high electrical conductivity or low electrical resistivity for electronic, anti-static, or electrostatic discharge (ESD) applications. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Electrical Insulating / Dielectric? | Dielectric resins, plastics, compounds, and encapsulants are electrically insulating. Dielectric compounds are used to form a barrier or isolator between electrical or electronic components. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

Material Type
Back to Top
|
|
| ||
| Your choices are... | |||
| Elastomer / Rubber | Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). Elastomers and rubber materials can be based on a variety of systems such as silicone, polyurethane, chloroprene, butyl, polybutadiene, neoprene, natural rubber or isoprene, and other synthetic rubber or compounds. | ||
| Metal / Metal Filled | Products are made of metal or filled with metal. | ||
| Plastic | Products are made of plastic. | ||
| Textile / Composite | Textiles are composite materials that consist of a resin reinforced with secondary fibers or particulates. | ||
| Other | Other material types. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
|
| ||
| Operating / Use Temperature: | The temperature range to which the material can be exposed without the degradation of structural or other required end-use properties. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
