I. Product Introduction
Pultruded insulation sections are made of glass-fiber reinforced epoxy composite insulating materials, includingvarious standard sections such as square tubes, rectangle tubes, cycle tubes, and bars, as well as various nonstandard sections tailored for clients. Our products could be made into various parts through proper connections and combinations, which could be widely used in different industries and fields such as power generation and distribution, railway system insulations, communications and transportations, for examples, insulation cross arms, insulation towers, crane spans, ladders, guard bars, power plant brackets, sports facilities, structural sections used in cooling towers, tool handles and other bearing structures.
The major features of the products are as follows:
1.1 Corrosion Resistance
Pultruded insulation sections have excellent resistances to acids, alkalis, salts and organic solvents as well as weathers. Therefore, they could be used in coastal areas, inland salinized soil areas, industrial areas and the areas with frequent acid rains.
1.2 Light-Weight and Non-Maintenance Demand
Pultruded insulation sections are made of composite materials with the weights of one second of those of the materials with the same mechanical strength. Therefore, the costs of transportation and installation as well as the manpower could be significantly reduced, especially in the mountainous and remote areas that can hardly be accessed. Given their unique performances in terms of insulation, weather-resistance and chemical resistance, the maintenances of composite materials could be reduced or exempted.
13. Anti-Aging Performance
Different from ordinary thermoplastic plastics, the Pultruded insulation sections could be used for decades.
1.4 Insulating Performance
Pultruded insulation sections have excellent insulating performance to ensure that no electromagnetic fields or sparks could be caused. The sectionscould be used in the equipment areas with electric conduction hazards and magnetic sensitivities as well as the areas with flammable and combustible materials.
1.5 Thermal Properties
Pultruded insulation sections are a kind of heat insulation material with thermal expansion coefficient that is much lower than that of the ordinary plastics, which could express excellentmechanical properties at low temperatures and will not melt at high temperatures. However, the strength and modulus may reduce to certain extent at high temperatures.
