Unsaturated polyester resin (UPE) * was one of the earliest liquid polymers to be rotationally molded. 3 oz. Nearly all resin acids have the same basic skeleton: three fused rings having the empirical formula C 19 H 29 COOH. The unsaturation present in this type of polyesters provides a site for subsequent cross-linking [23-24].Since 1930, unsaturated polyester resins have been used remarkably for wide range of applications making them a thermosetting system of major importance [25-26]. The miniumum ratio of catalyst is 1% and a maximum of 3% per weight of the product. Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following table.

Polyester resin generally costs slightly less than epoxy resin. As they are most typically used, they are solid at room temperature and will soften and flow between 150° and 220°F (65°C - 105°C). The glassfibre laminate made with this resin has excellent mechanical strength, good . ). Polyester: Unsaturated polyester resins (UPR) are the workhorse of the composites industry and represent approximately 75% of the total resins used. They are produced by the addition of α - β unsaturated carboxylic acids to epoxy resins. The most widely used epoxy resins are diglycidyl ethers of bisphenol-A derived from bisphenol-A and epichlorohydrin. Silicone resins are made up of a chain of alternating silicon and oxygen atoms like oils, but in the form of a 3-D network. Looking at the results, most resins show a linear shrinkage between 0,8 - 1,1%, which is considered very good. Step 2: Choose your resin For this demonstration, we are using our Super SAP CLR epoxy resin system from Entropy Resins.
