Specialty polymers and resins are proprietary polymers, resins, monomers and intermediates. This category includes plastics and elastomers that are based on proprietary curing technologies or chemistries, or that are designed for specialized applications. Specialty polymers and resins are available in a variety of forms. Resin raw materials include pellets, powders, granules, and liquids. Polymeric and elastomeric raw materials are available as stock shapes that can be used to fabricate parts. Specialty polymers and elastomers can also be used to create patterns, molds, and rapid prototypes. Electronic-grade products are used in thermal interface materials, potting and encapsulating compounds, conductive adhesives, and dielectric sealants. Optical-grade materials are used to develop transparent polycarbonate and acrylic lenses. Purging compounds are used to clean out molding machines between runs of different colors or compositions.

Mechanical and physical properties for specialty polymers and resins include flexural strength, tear strength, ultimate tensile strength, tensile yield strength, tensile modulus, elongation, and impact toughness. Flexural strength or yield is the maximum fiber stress that a specimen can withstand before cracking or breaking. Tear strength measures the tear resistance of thin, flexible materials. Ultimate tensile strength (UTS) is the maximum amount of stress required to fail or break a material under tension-loading test conditions. By contrast, tensile yield strength (YS) is the amount of stress required to begin to permanently deform the material. The tensile modulus (Young’s modulus, modulus of elasticity) is a material constant that indicates the variation in strain produced under an applied tensile load. Elongation is the percentage of deformation that occurs. The amount of energy absorbed measures the material’s impact toughness. Density, the mass per unit area, and water absorption are additional considerations.

Products & Services Related to Specialty Polymers and Resins
Anaerobic Adhesives and Anaerobic Sealants
Anaerobic adhesives and sealants cure in the absence of air or oxygen.
Electrical Resins and Electronic Compounds
Electrical resins and electronic compounds includes adhesives, greases, pads, stock shapes, tapes, encapsulants, potting compounds, thermal interface materials, and electrically conductive substances used in electrical, electronics, and semiconductor applications.
Hot Melt Adhesives
Hot melt adhesives are solvent-free chemical compounds that are used to join materials. They can be repeatedly softened by heat and hardened or set by cooling, allowing parts to be removed or repositioned during assembly.
Plastic and Rubber Balls
Plastic and rubber balls are sphere shapes that are used as check or ball valves, bearings, and in other applications.
Plastics and Plastic Materials
Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.
Rubber Adhesives and Sealants
Rubber adhesives and rubber sealants are highly flexible, natural or synthetic materials that are used to join components or fill gaps between seams or on surfaces.
Thermal Compounds and Thermal Interface Materials
Thermal compounds and thermal interface materials form a thermally conductive layer on a substrate, between components or within a finished product.
