FRP resin: What are the commonly used FRP resins?

Resin generally refers to an organic polymer that has a softening or melting range after heating, and has a tendency to flow under the action of external force during softening. It is a solid, semi-solid or liquid organic polymer at room temperature.

Features of unsaturated polyester resin

Unsaturated polyester resins are generally linear polymer chemical substances with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid unsaturated diols. Generally, the polyesterification polyaddition reaction is carried out at 190-220°C until the estimated acid value (or viscosity) is achieved. After the polyesterification polyaddition reaction is completed, add some vinyl monomer while it is hot. Formulated with thick solvents, such polymer solvents are called unsaturated polyester resins.

What are the types of gel coat resins and how to use them?

At this stage, the gel coat resins produced in China can be divided into ortho-benzene type, ortho-benzene (neopentyl glycol type, isophthalic type, isophthalic) neopentyl glycol type and vinyl ester type according to the types of conventional resins; it can be improved Glass fiber materials, improve the appearance quality of unsaturated polyester resin-based carbon fiber products, and maintain the solid layer of materials that will not be corroded by external natural environmental substances. Decoration design and maintenance of solid layer, gel coat resin.

Professional interpretation of the application prospects of pultrusion resin technology!

Pultrusion resin technology is a continuous automatic technology processing technology for the production of new composite materials with high fiber volume content, excellent performance and low cost. The resin viscosity can be adjusted in time, and the chemical fiber composition can reach 80%; the pultrusion type resin processing process is fully automated and controlled, and the production and manufacturing are highly efficient; the quality is the most stable, the repeatability is good, and the length can be disconnected at will; pultrusion There is no waste in the process of molding resin, and the product does not need post-production processing, which saves time and labor, raw materials, and energy consumption compared with other processing techniques. Therefore, once the pultrusion type resin is introduced, it has been widely paid attention to by the same industry all over the world.
