Rectangular and square Pultruded Fiberglass Reinforced Plastic tube

The basic components of the FRP profiles for the resin and glass fiber (including cloth, carpet, etc. ), which is based fibers (including glass fiber, carbon fiber, organic fiber and other metals, non-metallic fiber) as reinforcing material, resin (mainly polyester resin, epoxy resin, phenol resin) as crosslinking agent and other auxiliary materials supplemented (the main materials: Mold release agents, curing agents, catalysts, sealing mold agents, UV light stabilizers, mold clean water, gel coat, etc. ) composite made of. It has a high temperature, corrosion resistance, high strength, low specific gravity, low moisture absorption, good insulation and a small extension and a series of excellent properties. 

FRP Tube which is one of its main products. The product is a kind of structural plates which uses high-strength fiberglass roving as reinforcing material, thermosetting resin as the base and then is cast and formed on a special metal mold.

FRP tube can be used in electrical & electronics markets, chemical anti-corrosion markets , building construction markets , and foundation engineering markets .such as radome, insulation ladder,handrail, undergrand pression pipe, stairs,oversize bridge protection closed system, movable house structure, working platform, window frame, window sash and its components,freeway antiglare shield and its handrail, lamp post, water treatment, bracket for huge industry cooling tower, etc. It is an ideal loading frame on corrosion circumstances.

Pultruded FRP square tube sizes: 

1. Good dimensional stability
The thermosetting resin forming the substrate body crosslinked network structure in the process action of heat occurs, which article good dimensional stability under normal conditions, after the occurrence of shrinkage after molding is small. Products under long term continuous loads minimal change its shape and size, that little creep. Creep performance depends on the size of its load, high and low temperature and length of time of load factors. At a fixed load and temperature conditions, after a long time to load creep thermosets smaller than thermoplastics.
 
2. Excellent heat resistance, high temperature characteristics
Thermoset resin-based composite material can not be cured after softening, heat resistance and its products fairly stable, with a load of 1.86MPa, generally heat distortion temperature in the 150 ~ 260 ºC, and fiber-reinforced thermosetting plastics belong to excellent insulation material, the thermal conductivity is generally 0.35 ~ 0.47W / (mK), only metal 1/100 to 1/1000, it can be used as good insulation material and instantaneous high temperature materials, thermal deformation temperature of the material up to 350 ºC, can be used as normal and high temperature structural materials. Glass / phenolic rocket, missile engines excellent insulation material. 

3. Excellent electrical properties
Composites are excellent electrical insulation materials, more excellent terms of mica filler product obtained its electrical properties can be used to manufacture arc resistance, resistance, voltage, induction of superior special components. Since the composite material has excellent electrical properties, and its products there is no electrochemical corrosion and stray current corrosion, it can be widely used in the manufacture instrumentation, motors and electrical insulating components, in order to improve the reliability of electrical equipment and extend the life. In addition, the role of good products at high frequency and microwave dielectric properties permeability, has been used to manufacture a variety of high-frequency radar cover and other insulation products. 

4. Excellent corrosion resistance
Resin-based composite materials and electrochemical corrosion of ordinary steel mechanism is different, it is not conductive, dielectric solution does not dissolve the ions, so the air, water and general concentration of acid, alkali, salt and other medium has good chemical stability resistance, particularly in the non-oxidizing acid pH value and fairly wide range of media are having a good stability. Therefore, it is widely used to make corrosion-resistant products for stainless steel can not deal with some of the media (such as hydrochloric acid, chlorine, carbon dioxide, sulfuric acid, sodium hypochlorite and sulfur dioxide) corrosion, played a good role. 

5. FRP pultruded profiles good surface properties
When composite materials and chemical media generally have little contact surface corrosion generated, rarely scaling, so commonly used for producing a fluid conduit, its pipeline small resistance, low friction coefficient, saving a lot of power. Since the composite material is generally not as easily as metal ions to form metal contaminated media, so it is widely used in food and pharmaceutical industries composite article reason. In addition, the composite material has a high friction (PV) limit under water lubrication, the friction coefficient is very small, about 0.01 to 0.03, it is also preferred material wear-resistant products.
