The choice of adhesive component depends on the two surfaces to be laminated. The strength of the lamination adhesive depends on the combination of cohesive strength and adhesive strength of the adhesive. The cohesive strength is affected by Tg and elongation, while the bond strength is affected by wetting and interfacial synergism.
There are three different types of lamination adhesives: cold lamination allows us to use a laminate with adhesive on one side to cover both sides of the page. Apply a cold lamination so that the edges of the material do not remain around the outer edge. It simply discharges the plastic coating on the surface of the sheet. Thermal lamination is used to completely pack paper. The laminate is heated and applied to the substrate to form an airtight and watertight seal. Thermal lamination has a variety of thicknesses, thickness of 1-6 mils, dull or glossy. Liquid lamination is a coating that provides UV coating protection, image enhancement and wear.
It may be a challenge to find a material that has the necessary performance for a particular lamination adhesive application. And then found that the required thickness of the material is almost impossible, because most rubber and sponge manufacturers can only produce standard size materials. Special runs can be made for a particular thickness, but usually require the smallest order, its associated high cost and long delivery time. More cost-effective resolution (especially for lower volumes) can be to laminate a variety of standard sheets to meet the desired thickness.
Lamination adhesives can address different frequencies in shock isolation applications. Durable, non-slip materials can be used in foams, sponges and solid elastomers to increase pad life. The conductive material may be supported by a compressible foam or sponge material to act as a spring in a battery case or ESD buffer application. Whether you are laminating adhesives or using high-performance adhesives to build multilayer elastomers, Joyachem.com will help meet specific material requirements.
