It can handle heat exposure up to 350 °F (177 °C), beyond this temperature Epoxy Resin is used. Phenolic Resin and Epoxy Resin are both functionally equivalent, but differ in their heat handling abilities. Other materials to build laboratory countertops may include plastic laminate, stainless steel and even wood. [1] [unreliable source?]
Epoxy resin formulations are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, insulators, printed wiring boards (PWB), and semiconductor encapsulants. Epoxy resins are excellent electrical insulators and protect electrical components from short circuiting, dust and moisture.
[9] [10] The manufacturing of epoxy resins and vinyl ester resins account for 25–30% of BPA use. [9] [10] The remaining 5% is used as a major component of several high-performance plastics, and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, [11] although it is often wrongly ...
Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...
Bakelite resin could be provided either as powder or as preformed partially cured slugs, increasing the speed of the casting. Thermosetting resins such as Bakelite required heat and pressure during the molding cycle but could be removed from the molding process without being cooled, again making the molding process faster.
