Pultruded Epoxy Products Applications

Unsaturated polyester resin is the most common resin which is used in fiberglass pultruded products, and then epoxy resin. It is mainly used for products with high requirements on mechanical properties and heat resistance. Besides those two types of resin, vinyl ester resin, phenolic resin and  thermal plastic resin are also used during production. The resin requirements in pultrusion technology is: low viscosity, easy to saturate the reinforced material;  fast curing to adapt to the requirements of continuous forming production; good adhesion, curing shrinkage rate. Flexibility is good, the product is not easy to have cracks. Epoxy resin pultruded profiles are important type of glass fiber reinforced plastic material, and they have excellent strength properties.
Applications of fiberglass pultruded epoxy resin products:
1). Electrical engineering is the most widely used area currently, and it is very important development. Such as the transformer air catheter positioning rod, high voltage insulator core, high-voltage cable protection tube, cable rack, insulative ladder, insulating rod, pole, rail guard board, cable distributing frame, motor spare parts etc.
2). chemical anti-corrosion field is the fastest developing field in recent years. Typical products such as supporting structure of pipe network, pumping rod, downhole pressure pipeline, wastewater treatment equipment,, baffle of chemical industry, petroleum, chemical industry, papermaking, metallurgy and other factories in the railings, stair and platform railing, the grid floor.
3). Building construction, the structure is mainly used in the light structure, the upper structure of the high-rise structure or special purpose structure. Such as the activity of the housing structure, doors and windows structure with profile, truss, light bridge, railing, tent, suspended ceiling, structure, etc.
4). Sports and entertainment areas such as fiberglass fishing rod, hockey stick, ski pole, pole vault, bow etc.
5). Transportation areas such as automotive shelves, truck frame, refrigerated car, car spring board, luggage rack, insurance, deck, electric train track board, etc.
6). The energy field is mainly used in the solar collector, the wind turbine blade, the oil well and so on.
7). Aerospace applications such as aircraft and spacecraft antenna insulating tube, the spacecraft motor parts, fiberglass I beam, trough shaped beam and square beam, fiberglass rods, etc.

Types Of FRP Tubes

There are many types of fiberglass tubes, today we'll introduce three types of tubes from aspects of production process, cross sections and raw materials.
1. According to the production process, frp tubes can be divided into pultruded tubes, pulwinding tubes, filament winding tubes, roller, etc. Filament winding pipe is widely used in the pipeline, and it has the advantages of high transverse strength, longitudinal strength, the disadvantage is it can't be produced continuously. For pultruded tubes, we can add the enhancement layer to increase the transverse strength, and the surface finish is very smooth, they can be produced continuously , and products can be customized according to customer's demand, the production efficiency is very high high, the disadvantage is that too large product is difficult to achieve, and it has high requirements of the machine and process. And fiberglass tubes with small and medium size have wide application.
2. According to the cross section shapes, fiberglass tubes can be divided into round tubes, square tubes, fiberglass rectangular tubes, etc, and our factory is able to manufacture different tubes at customer's request. 
3. According to the raw materials, now the most common resin is polyester resin tubes, there are vinyl ester resin, epoxy, phenolic, and other fiberglass tubes, different raw materials will produce tubes with different physical, mechanical and chemical properties. And according to the specific use of the environment, we are able to do customized production and processing of glass fiber tube to meet customer requirements.
As the fiberglass products have more and more applications in our life, we can see more fiberglass products in daily life. FRP tube as a very important branch of fiberglass products, it gets more recognition in different industries because of its various performance characteristics.
