FRP pultruded profiles are widely used in the market, and most of them should have high hardness, good color, and smoothness. So what is its main material? What should be paid attention to in the processing process? The following is a detailed introduction to its raw materials.
The characteristics of FRP pultruded profiles are determined by the characteristics of its constituent materials. In addition to FRP fibers, its constituent materials also contain a certain amount of resin and some other composite materials. The combination of these materials It can be made into high-quality pultruded profiles.
If the raw materials are well selected, the produced profiles can also have good effects. For example, the surface is relatively flat, the gloss is good, and the strength is very high. In addition, there is a certain toughness. These characteristics make the FRP pultruded profiles The application range is very wide. However, if a resin of poor quality is selected from the raw materials, the produced profiles will have pores, which will be easily broken after long-term use, reducing the service life, and the strength and toughness will also be affected accordingly.
The FRP pultruded profiles processed from inferior raw materials not only have poor appearance, but also have pores and horizontal columns, and the color is not pure, so the price is not as high as the quality, and there is no good market when it is sold. Therefore, when manufacturers produce, they would rather increase the cost and select good raw materials for production, rather than shoddy ones. The produced profiles are not only low in price, but also difficult to sell.
