Unsaturated Polyester Resin UPR high strength light weight corrosion resistance ease of moulding

Product Description:

Unsaturated Polyester Resin (UPR), is a type of synthetic resin characterized by its repeating ester bonds and unsaturated double bonds in its molecular backbone. This unique chemical structure allows it to exhibit high reactivity, enabling copolymerization reactions with vinyl monomers like styrene. When combined with these monomers and a catalyst, UPR forms a durable, three-dimensional network structure that is insoluble and non-melting. It is widely used in various applications such as composites, construction, shipbuilding, automotive, and furniture due to its high strength, light weight, corrosion resistance, and ease of moulding.
