Information about 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. Natural rubber is based on polyisoprene. Synthetic rubbers and elastomers include silicone, polyurethane, polysulfide, styrene-butadiene rubber (SBR), butyl, acrylic or polyacrylate, isoprene, polyisobutylene, ethylene-vinyl acetate (EVA), vinyl and nitrile compounds. Pressure sensitive adhesives (PSAs) are often based on non-crosslinked rubber adhesives in a latex emulsion or solvent-borne form. Rubber adhesives and rubber sealants are also available as aerosols, films, gels, liquids, slurries, solids, pastes, powders, and putties. They are compatible with substrates made from ceramics and glass, concrete and masonry, paper and paperboard, rubbers and elastomers, leather, textiles, metal, plastic, wood, porous surfaces, and composite materials. Rubber adhesives and rubber sealants are used in a variety of aerospace, automotive, electrical, electronic, marine, medical, and military applications. They are also used in abrasives, optics, photonics, and semiconductors.

Conductive Adhesives and Compounds

Conductive adhesives and compounds provide an electrically and/or thermally conductive path between components.

Conformal Coatings

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.

Epoxy Adhesives

Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.

Gel Elastomers

Gel elastomers are highly viscoelastic polymer gel materials that have excellent shock absorption and damping characteristics. They are available in a variety of material types and grades.

Pressure Sensitive Adhesives (PSA) and Contact Adhesives

Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water based forms.

Silicone Adhesives and Sealants

Silicone adhesives and silicone sealants have a high degree of flexibility and very high temperature resistance.

Thermoplastics and Thermoplastic Materials

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.
