What are some examples of where polyester resins are used in construction?
Wall panels fabricated from polyester resins reinforced with fiberglass—so-called fiberglass reinforced plastic (FRP)—are typically used in restaurants, kitchens, restrooms and other areas that require washable low-maintenance walls. They are also used extensively in cured-in-place pipe applications.
What are some of the uses of polyester resin?
The clear polyester resin is used in Jacuzzis, ponds, swimming pools, and other outdoor applications. Other applications include: Homebuilding or construction materials. Used in aircraft, vehicles, and the marine industry.
What is UPR used for?
The major driver of consumption for UPR is the construction industry, in which UPR is used mainly for bathroom components and fixtures, corrosion-resistant tanks, pipes and ducts, cultured marble, and panels for floor and walls.
What are the advantages of polyester resin?
Polyester resin offers many advantages, such as: low cost, adequate resistance to water and many chemicals, resistance to weathering and aging, reasonable temperature resistance (up to 80°C), good wetting to glass fibers, low shrinkage (4%–8%) during curing, and linear thermal expansion (100–200·10−6 K−1).
Is an example of polyester fabric answer?
Terylene is an example of polyester fabric and is used in the making of fine yarn.
What are the uses of resins in our daily life?
Plant resins are valued for the production of varnishes, adhesives, and food glazing agents. They are also prized as raw materials for the synthesis of other organic compounds and provide constituents of incense and perfume.
What is an unsaturated polyester?
unsaturated polyester, any of a group of thermosetting resins produced by dissolving a low-molecular-weight unsaturated polyester in a vinyl monomer and then copolymerizing the two to form a hard, durable plastic material. Bowling balls are made from unsaturated polyesters cast into molds with no reinforcement.
What is fiberglass resin used for?

What is meant by polyester resin?
Polyester resins are unsaturated synthetic resins that form when polyhydric alcohols and dibasic organic acids react. Maleic anhydride, which has diacid functionality, is commonly used as a raw material to produce polyester resins.
Are unsaturated polyester resins suitable for glass fibre reinforced composites?
Introduction Unsaturated polyester resins are one of the most important matrix resins for commodity glass fibre reinforced composites .
What is ecological unsaturated polyester resin?
These new ecological unsaturated polyester resins will be used for marine, automotive, electric and electronic, building construction, sport and leisure, domestic and sanitary appliances, furniture as well as military applications.
What is low styrene emission polyester resin?
Low styrene emission polyester resin The unsaturated polyester normally blended with styrene to a reactive resin solution. The styrene acts both as a cross-linking agent and as a viscosity reducer so that the resin can be processed. In conventional unsaturated polyesters the styrene content varies between 35- 45wt %.
What type of diluent should I use to cure polyester resin?
The type of reactive diluent will effect both the cure and the final properties of the polyester. Unsaturated polyester resins are produced on a large scale by a large number of companies including Ashland, Reichhold, and Royal DSM . They are typically sold in liquid form in an unsaturated and reactive solvent, normally styrene.
