“Polyester” is a type of polymer containing ester bonds, distinguished from resins such as phenolic and epoxy. This polymer is produced through a polycondensation reaction between a diacid and a diol. When this polymer contains unsaturated double bonds, it is referred to as unsaturated polyester. When this unsaturated polyester dissolves in a polymerizable monomer (usually styrene) and forms a viscous liquid, it is called unsaturated polyester resin.
Specific types of unsaturated polyester resins include winding resins, spray-up resins, RTM (Resin Transfer Molding) resins, pultrusion resins, SMC (Sheet Molding Compound) resins, BMC (Bulk Molding Compound) resins, flame-retardant resins, food-grade resins, anti-corrosion resins, air-drying resins, polyester panel resins, craft resins, button resins, agate resins, artificial stone resins, high transparency resins, crystal resins, and automotive putty resins.
Based on their structure, unsaturated polyester resins can be classified into ortho-phthalic, iso-phthalic, terephthalic, bisphenol-A, and vinyl ester types.
Based on their performance, they can be divided into general-purpose, anti-corrosion, self-extinguishing, heat-resistant, and low-shrinkage types.
Additionally, they can be categorized by their primary use into two main groups: resins for fiberglass-reinforced plastic (FRP) and resins for non-FRP applications. Fiberglass-reinforced products refer to those made from resin reinforced with fiberglass and its products, also known as fiberglass-reinforced plastics (FRP). Non-FRP products are made from resin mixed with inorganic fillers or used alone, also referred to as non-reinforced fiberglass products.
Unsaturated polyester resin has extensive applications in the construction industry. It is mainly used for coatings on walls, roofs, floors, and metal surfaces, offering excellent corrosion resistance, waterproofing, and anti-aging properties, thereby ensuring the long-term durability and decorative effect of buildings. Additionally, this resin is used in manufacturing construction equipment such as doors, windows, railings, bridges, and partitions. Its superior pressure resistance, impact resistance, wear resistance, and easy processing make it a key material for meeting various construction needs, ensuring the safety and reliability of buildings.
Fiberglass sanitary equipment primarily includes bathtubs, wash basins, toilets, mirror frames, integrated bathrooms, and trash bins. These products, made from unsaturated polyester resin, offer advantages such as lightweight, corrosion resistance, easy processing, and design flexibility. Compared to traditional ceramic or metal sanitary equipment, fiberglass sanitary equipment is easier to clean and maintain and has a longer service life. Additionally, these products are energy-saving and environmentally friendly, as integrated bathrooms and trash bins can effectively reduce water waste and environmental pollution. Therefore, fiberglass sanitary equipment is widely used in modern homes and public facilities.
Unsaturated polyester resin is extensively used in manufacturing fiberglass vehicles. Specifically, this resin is used to produce double-decker train cars and their parts, window frames, car bodies, bumpers, train ventilation ducts, and spring boards. Its excellent mechanical properties, corrosion resistance, and moldability make it highly suitable for manufacturing these vehicle components.
Energy-saving fiberglass products mainly include axial fans, centrifugal fans, solar water heaters, and wind turbines. These products utilize the lightweight, high strength, and corrosion-resistant properties of fiberglass to achieve energy-saving and environmental goals. For instance, axial and centrifugal fans are widely used in ventilation and air conditioning systems, effectively reducing energy consumption. Solar water heaters convert solar energy into thermal energy, reducing dependence on electricity. Wind turbines generate electricity from wind energy, reducing fossil fuel consumption. These products collectively represent important applications of energy-saving fiberglass products.
Unsaturated polyester resin is widely used in fiberglass pipes, tanks, anti-corrosion products, and engineering. These products are primarily used for pipes, fittings, valves, storage tanks, gratings, storage boards, towers, chimneys, and anti-corrosion flooring in various diameters. Due to their excellent anti-corrosion properties, these fiberglass products are extensively used in chemical, petroleum, food, pharmaceutical, and other industries, ensuring the safety and stability of engineering projects.
Fiberglass is widely applied in traffic equipment and safety and security products. Applications include road signs, pedestrian bridges, lamps, cable boxes, measuring rulers, helmets, booths, explosion-proof equipment, and manhole covers. These products not only possess the lightweight, high strength, and corrosion-resistant characteristics of fiberglass but also meet the specific demands of traffic and safety. For example, helmets and explosion-proof equipment require high protective performance, while road signs and markers need weather resistance and durability. Overall, the application of fiberglass in these fields enhances product performance while reducing costs and weight.
Fiberglass food containers are mainly used for transporting, storing, and selling food. These containers include high-level water tanks, food transport tanks, and beverage cans. Made from unsaturated polyester resin, these materials offer excellent corrosion resistance and mechanical strength, making them suitable for the food industry. Additionally, fiberglass is used in making city sculptures, letters, crafts, inlay crafts, various furniture, and electromechanical products.
Artificial stone is a synthetic material that mimics natural stone, including artificial marble, agate, and granite. These materials, composed of unsaturated polyester resin, fillers, and other additives, have a similar appearance and performance to natural stone. The unsaturated polyester resin acts as a binder and curing agent, ensuring the artificial stone’s required strength, durability, and stability. Therefore, artificial stone is widely used in construction, decoration, and furniture manufacturing due to its lower cost and easier processing and installation.
Unsaturated polyester resin has broad applications in the coatings industry. It is used to produce furniture coatings, piano finishes, TV and radio casings, sewing machine tabletops, and bicycle varnishes. Its advantages include excellent weather resistance, corrosion resistance, UV resistance, and heat resistance, providing long-lasting protection and decorative effects in various applications.
Unsaturated polyester resin has extensive applications in the manufacturing industry, particularly in producing various products where it outperforms other resins. Its excellent properties make it the material of choice in manufacturing. It can be used to produce items of various shapes and sizes, featuring high plasticity and durability. These characteristics enable unsaturated polyester resin to meet complex and diverse demands in the manufacturing process, making it stand out among many resins.
