|
| |
Ethylene Copolymer (EEA, EVA, EBAC)
|
|
Ethylene copolymers include (poly)ethylene acrylate acid (EAA), (poly)ethylene methyl acrylate (EMAC), (poly)ethylene ethyl acrylate (EEA), (poly)ethylene vinyl acetate (EVA), (poly)ethylene butyl acrylate (EBAC), (poly)ethylene vinyl acetate (EVA or EVAC), (poly)ethylene vinyl alcohol (EVAL or EVOH), and (poly)ethylene propylene terpolymer (EPM).

Glue / Gum
|
|
Animal glues include hide glues, casein or milk protein glues and fish-based glues. Hide glues are produced by hydrolysis or by boiling collagen, protein or gelatin from animal bones, hide, hooves or horns. Collagen, hide glue and gelatin are very closely related in terms of protein and chemical composition. Casein-based adhesives (carpenter's glues) are derived from milk. Vegetable glues are made from plant-based proteins or modified starches. Soy protein glues are finding increased application.
Gum adhesives or mucilage are based on polysaccharides derived from various plant exudates such as an oleoresin or gum resin. Gum adhesives are gelatinous when moist and harden on drying. Gum adhesives are the salts of complex organic acids. Mucilage contains proteins and polysaccharides and is similar to vegetable plant gums adhesives. Mucilage is a gelatinous substance extracted from legumes and seaweeds.
|
| |
Styrene Copolymer (SIS / SBS)
|
|
Products are based upon a styrene copolymer system such as styrene acrylonitrile (SAN), acrylic styrene acrylonitrile (ASA), acrylonitrile ethylene styrene (AES), styrene maleic anhydride (SMA), styrene-isoprene-styrene (SIS), styrene-butadiene-styrene (SBS), or styrene butadiene rubber (SBR).
Styrene butadiene rubber (SBR) has good resistance to petroleum hydrocarbons and fuels. SBR is used widely with oils, hydraulic fluids, and alcohol. Many compound variations are available for specific applications. The suggested operating temperature for SBR is -30° to 275° F. Styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) copolymers are commonly applied in pressure-sensitive adhesive applications.
|
| |
Rubber Based / Elastomeric
|
|
Products use a rubbery or elastomeric bond system. Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). Natural rubber, synthetic rubber or elastomer sealants and adhesives can be based on a variety of systems such silicone, polyurethane, chloroprene, butyl, polybutadiene, isoprene or neoprene.
|
| |
Silicone

Plastic compounds, elastomer resins or polymers are based on the silicone chemical system. Silicones are produced through the hydrolysis and polymerization of silanes and siloxanes.
|
| |
Starch / Starch Paste
|
|
Starches and starch pastes are derived from flours or vegetable matter. Starches are useful additive materials for thickening and other functions. Pastes are commonly applied in light duty adhesive application on paper products such as envelopes, stamps, labels or paper packing tapes. Starch-based pastes are low cost, non-toxic and water activated. In their dry state, water-activated adhesives are not sticky, but upon wetting become adhesive.
|
| |
Vinyl (PVC / PVA / PVDC)
|
|
Polymers are based on the vinyl chemical system. Examples include polyvinyl chloride (PVC), polyvinylidene chloride (PVDF), polyvinyl vinyl acetate (PVA), and polyvinyl alcohol (PVOH).
|
| |
Wax Based
|

Ceramic / Glass
|
|
Ceramics consist of oxides, carbides, nitrides, carbons and other non-metals with high melting points. Ceramics are suitable for applications requiring wear resistance, refractoriness, low electrical resistivity or other specialized characteristics.
|
| |
Concrete / Masonry
|
|
Concrete and cements consist of a mixture of a binder or clinker and a coarser aggregate. They are used to patch or line floors and walls, bond brick, and join components for use in high temperature applications. Clinker is a fused mineral or mineral mixture, such as alumina or bauxite and lime, which is crushed into a fine powder to manufacture cements. Aggregates are coarser, granular materials that are added to mortar, grout or cement at mixing time to impart special properties such as refractoriness, erosion resistance, and oxidation resistance. Synthetic aggregates are fused mineral or mineral mixtures crushed to a coarse, granular size range rather than a fine, powdered clinker. Portland cement is the most common bond used in structural concretes and mortars. Polymer cements have a resin bond and are used in corrosion protection, mortars for corrosion-resistant floor tiles, and other specialized industrial applications. Masonry consists of tile, bricks, stone or other ceramic components bonded together with mortar or adhesive.
|
| |

|
Metals are opaque, fusible, ductile, and typically lustrous substances that are good conductors of heat and electricity. They form cations by the loss of electrons and yield basic oxides and hydroxides. Metals that are used in structural engineering applications have a high toughness that is a combination of high strength and ductility.
|

|
| |
Rubber / Elastomer
|
|
Rubber and elastomers are characterized by a high degree of flexibility and elasticity (high reversible elongation). Natural or synthetic rubber is vulcanized to increase useful properties such as toughness and resistance to wear for use in tires, electrical insulation, and waterproof materials. Vulcanization is a chemical treatment that adds sulfur and heat to crosslink the rubber. Natural rubber is an elastic substance that is obtained by coagulating the milky juice of any of various tropical plants. Essentially, natural rubber is a polymer of isoprene, and is prepared as sheets and then dried. Synthetic rubbers or elastomers can be based on a variety of systems such as silicone, polyurethane or neoprene.
|
| |
Textiles / Fabrics
|
|
Substances are adhesives or sealants suitable for coating, filling, sizing or sealing non-woven or woven textiles. Sizing adhesives or resins are used to fill in paper, textile webs, and other fibrous products.

Wood / Wood Product
|
|
Wood is a natural composite extracted from the stems, branches, and roots of trees. Wood is a hard fibrous substance that consists of xylem, cellulose fibers in an amorphous, lignin polymer matrix. Lignin is a biogenetic crosslinked polymer which bonds together adjacent cell walls into the straw or wood tissue composite. Cellulose is a polysaccharide (C6H10O5)x of glucose units that constitutes the chief part of the cell walls of plants. It occurs naturally in fibrous products such as cotton and kapok, and is the raw material of many manufactured goods as paper, rayon, and cellophane.
