191 unsaturated polyester resin is a commonly used synthetic resin with excellent physical properties and chemical stability widely used in construction, automotive, marine, electronics, furniture and other fields.
191 unsaturated polyester resin is produced by polymerisation reaction of unsaturated acid, alcohol and diluent and other raw materials. It has good fluidity and plasticity, and can be processed into various shapes of products through moulding, injection moulding, spraying and other processes. At the same time, it also has excellent corrosion resistance heat resistance and weather resistance, can be used in harsh environments for a long time.
In the construction field, 191 unsaturated polyester resin is widely used to make FRP products, such as water tanks, storage tanks and pipes. These products have the characteristics of light weight, high strength, corrosion resistance, etc., and can meet the needs of buildings in different environments. In the field of automobiles and ships, unsaturated 191 polyvinyl acetate resin is used to make body, hull and other parts. These parts are lightweight, high-strength, corrosion-resistant, etc., and can improve the performance and service life of automobiles and ships.
In the field of electronics and furniture, 191 unsaturated polyester resins are used to make shells, panels and other parts. These parts have good surface gloss and abrasion resistance, which can improve the appearance and service life of the product.
191 unsaturated polyester resin is an excellent synthetic resin with a wide range of application prospects. With the continuous progress of science and technology and the continuous expansion of application fields, it will be used in more fields.
191 resin is unsaturated polyester resin for general purpose with its cheap price and high quality so that it has a good reputation in Chinese market. And it is welcomed by many Chinese FRP munufacturers.
