What are the resins suitable for FRP process?

A lot of commonly used Unsaturated Resin, as a professional unsaturated Resin , Vinyl Resin, Epoxy Resin and other composite materials one-stop suppliers detailed for everyone to introduce suitable for FRP products process resin types and resin characteristics!

FRP is mainly a composite material based on thermosetting resin. The commonly used FRP resins are Epoxy resin, unsaturated resin, vinyl resin and phenolic resin. Epoxy resin is mainly used in the field of corrosion resistance and high strength; Phenolic resin for anti-corrosion field; Unsaturated resins and vinyl resins are the most commonly used in the general field. This is determined by their own characteristics.

Such as vinyl resin molecular chain at both ends of the double bond is extremely active, so that vinyl resin can quickly cure, quickly get the use of strength, get a high corrosion resistance polymer; Using methacrylic acid synthesis, methyl group of ester bond edge can play a protective role, improve the hydrolysis resistance; Resin contains less ester bond, per mole than the chemical resistant polyester less 35-50%, improve its alkali resistance; More secondary hydroxyl can improve the wettability and cohesiveness of Glass Fiber, and enhance the mechanical strength of glass fiber.

Vinyl Polyester Resin is a kind of Unsaturated Polyester Resin dissolved in styrene liquid containing unsaturated double bond special structure, is internationally recognized as a highly corrosion resistant resin, better than benzene type unsaturated resin, mechanical properties and standard epoxy vinyl resin equivalent, especially fatigue resistance and dynamic load performance, but also has good weather resistance and glass fiber infiltration performance and process performance. Suitable for all kinds of FRP molding process, including fiber winding, pultrusion, hand paste, spray and other composite materials process. And flame retardant vinyl resin using bromine epoxy resin synthesis, because it contains bromine, so flame retardant vinyl resin has chemical resistance at the same time, but also flame retardant, so it is commonly used as a raw material of glass steel products.
