Superconductors and superconducting materials conduct electricity without resistance.
Learn MoreAdhesive tapes and films temporarily or permanently join materials together.
Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
Search by Specification | Learn MoreFabricated plastic parts and semi-finished shapes include molded, cast, extruded and machined parts made from any polymeric materials.
Search by Specification | Learn MoreThermal compounds and thermal interface materials form a thermally conductive layer on a substrate, between components or within a finished product.
Search by Specification | Learn MorePolymer and plastic composites are strengthened with fibers, fillers, particulates, powders and other matrix reinforcements to provide improved strength and/or stiffness. Examples of polymer and plastic composites include fiber reinforced plastics (FRPs), sheet molding compounds (SMCs), bulk molding compounds (BMCs), pre-preg materials, and fabricated composite parts
Search by Specification | Learn MoreNon-destructive testing (NDT) conductivity meters and resistivity meters are devices for measuring electrical conductivity and/or resistivity of solid media to determine the characteristics of its constituent materials
Search by Specification | Learn MoreConductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample
Search by Specification | Learn MoreComposite materials typically consist of a matrix and a dispersed, fibrous or continuous second phase. The second phase may reinforce (strengthen or stiffen) the material, alter electrical or magnetic properties, or enhance wear or erosion resistance
Learn MoreZero speed switches are devices used to detect stoppage of a rotating shaft. They typically have one or more relays
Search by Specification | Learn MoreLaminating adhesives and composite resins are cured using heat and/or heat and pressure
Learn MoreComposite and fiberglass molding services perform injection molding, blow molding, compression molding, rotational molding, thermoforming, and dip molding
Search by Specification | Learn MoreAramid fiber and fabrics consists of bulk, chopped fibers, continuous strands or woven cloth forms of aromatic polyamide thermoplastic for reinforcing polymer matrix composites and other applications
Learn MoreCarbon fiber and carbon fiber cloth consist of bulk, chopped fibers, continuous strands or woven cloth forms of carbon or graphite. Carbon and graphite are used in reinforcing composites as well as other specialized electrical and thermal applications
Learn MoreFoam, honeycomb and core materials are plastics, ceramics or metals containing closed or open internal cells or pores for composites, tooling, modeling, insulation or floatation
