The basic components of extruded fiberglass profiles are resin and glass fiber (including cloth, felt, etc.). It is reinforced with fibers (including glass fiber, carbon fiber, organic fiber, and other metal and non-metal fibers), resin (mainly epoxy resin, polyester resin, phenolic resin) as the bonding agent, and other auxiliary materials (mainly mold release agent, curing agent, catalyst, sealing agent, UV light stabilizer, mold cleaning water, adhesive coating, etc.). It has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, low elongation, and good insulation. Application of extruded profiles: high voltage electricity.

Application of extruded profiles:


High voltage cable trays, insulation support components, antenna columns, high-voltage power operating poles, generator radiators, stairs and handrails, operating platforms, corridors, oil storage tanks, distribution boards and rooms, drainage systems, berth and seabed identification signs, pressure rods in trains and cars, corner boards, highway guardrails, sound-absorbing panels, filling supports in towers, filter plate brackets, and frame materials for cold storage.


Characteristics and performance


1. Good dimensional stability


The thermosetting resin matrix undergoes cross-linking under heat during processing to form a network like structure. Its products have good dimensional stability under normal conditions, and the post shrinkage after molding is also small. The shape and size of the product change very little under long-term continuous load, that is, the creep deformation is small. Its creep performance depends on factors such as the size of the load, temperature, and loading time. Under fixed load and temperature conditions, the creep deformation of thermosetting plastics after long-term loading is much smaller than that of thermoplastic plastics.


2. Excellent heat and high temperature resistance characteristics


Thermosetting resin based composite materials can no longer soften after curing, and their heat resistance is quite stable. When tested under a load of 1.86MPa, their thermal deformation temperature is generally within 150-260 ℃. Fiber reinforced thermosetting plastics are excellent insulation materials, with a thermal conductivity of 0.35-0.47W/(m.K), which is only 1/100 to 1/1000 of that of metals. They can be used as good insulation materials and instant high temperature resistant materials, with a thermal deformation temperature of up to 350 ℃, and can be used as structural materials at room temperature and high temperature. Fiberglass/phenolic resin is an excellent insulation material for rocket and missile engines.


3. Excellent electrical performance


Composite materials are excellent electrical insulation materials, and products made with mica as a filler have even better electrical properties. They can be used to manufacture special components with excellent arc resistance, voltage resistance, and induced electrical properties. Due to the excellent electrical properties of composite materials, their products are free from electrochemical corrosion and stray current corrosion, and can be widely used to manufacture insulation components in instruments, motors, and electrical appliances, in order to improve the reliability of electrical equipment and extend its service life. In addition, the product has good dielectric properties and microwave transparency under high-frequency action, and has been used to manufacture various high-frequency insulation products such as radar covers.


4. Excellent corrosion resistance


The electrochemical corrosion mechanism of resin based composite materials is different from that of ordinary steel. It is non-conductive and does not dissolve ions in dielectric solutions. Therefore, it has good chemical stability to atmospheric, water, and general concentrations of acids, bases, salts, and other media, especially in non oxidizing strong acids and media with a wide range of pH values. Therefore, it is widely used in the manufacture of corrosion-resistant products for the corrosion of certain media that stainless steel cannot handle, such as hydrochloric acid, chlorine gas, carbon dioxide, dilute sulfuric acid, sodium hypochlorite, and sulfur dioxide, and has played a good role.


5. Good surface properties of fiberglass extruded profiles


When composite materials come into contact with chemical media, there is generally little corrosion or scaling on the surface. Therefore, they are commonly used to manufacture fluid pipelines, which have low internal resistance and friction coefficient, saving a lot of power. Due to the fact that composite materials generally do not easily generate metal ions to contaminate the medium like metals, this is also the reason why composite material products are widely used in the food and hospital industries.


The above-mentioned superior characteristics of pultruded composite materials are widely used in mechanical structural components, insulation components, high-frequency load-bearing components, and other functional structural parts.
