Product description
phenolic paper is called phenolic laminated sheet.  a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with phenolic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.

SMC and BMC are abbreviations of respectively Sheet Molding Compound and Bulk Molding Compound. SMC and BMC form a family of structural, fiber reinforces thermosetting resins. SMC and BMC are intermediate materials from which a large variety of products can be manufactured by compression molding or injection molding. Base materials of SMC and BMC are, generally spoken, unsaturated polyester resins, glass and mineral filler materials, such as chalk or aluminum trihyd rate. The composition of the compounds can be adapted to the application where it is used for. Specific properties such as flame retardancy, surface quality and paintability can be achieved by adding specific, functional materials. SMC and BMC product are used in a very broad range of applications.
