Unsaturated Polyester Resin Classification


According to its structure, pultruded punsaturated polyester resin can be divided into phthalic type, isophthalic type, terephthalic type, bisphenol A type, vinyl ester type, etc.

According to its performance, it can be divided into general-purpose type, anti-corrosion type, self-extinguishing type, heat-resistant type, low shrinkage type,etc.

It can be divided into two types according to their main purpose: fiberglass (FRP) resin and non-fiberglass (FRP) resin. Fiberglass products are made using resin and reinforced fiberglass materials which are also called fiberglass reinforced products (shortened as “FRP”).Non-fiberglass products are mixed with resin and inorganic fillers which are also known as non-reinforced fiberglass products.

According to the specific varieties, it includes winding resin,spray resin, RTM resin, pultrusion resin, SMC resin, BMC resin, flame-retardant resin, food grade resin, anti-corrosion resin, air-drying resin, Polaroid board resin, arts and crafts resin, buttons resin, agate resin, artificial stone resin, a highly transparent resin crystal resin, putty resin.

As FRP surface decoration, there are aging retardant gel coat, heat-resistant gel coat, spray gel coat, mold gel coat, non-cracking gel coat, radiation curable gel coats, high wear-resistant gel coat and so on.
