Pultrusion is an economic and resource-efficient technology for manufacturing of composite materials. Due to its numerous benefits, products made by pultrusion are broadly applied in different branches of industry:
In the agriculture and chemical industries for manufacturing of chemically resistant to aggressive media slatted floors with enhanced strength characteristics; used in the construction of livestock facilities, chemical plants, etc.;
In the construction industry for the production of glass-fiber reinforcement, profiles, carcasses, stiffening bars for PVC-windows, etc.;
In electrical power engineering for manufacturing of dielectric structures, fiberglass rods used in composite insulators and as supporting structures for elements of signaling blocks, and fiberglass profiles used in manufacturing of transformers and electric motors;
In the aerospace industry for manufacturing of structure components of aircraft;
In the sports and tourism industries for manufacturing of equipment exhibiting enhanced strength properties: skis, ski poles, golf course flagsticks, tent and hovel constructions, etc.;
In the automotive industry for the production of structural and complex parts of the vehicles with enhanced stiffness, rigidity and lightness.
In many other industries and plants, using mechanisms, structures and materials which meet high standards of chemical, dielectric and strength stability.
Pultrusion with the use of polyurethane resin allows to obtain composite materials of increased tensile strength, shock elasticity and abrasibility compared to composites based on polyester resins and vinyl ester resins. The additional benefit of using PUR resin is a 40 - 60% larger force required to tear off joints screwed directly into the composite. Composite materials produced with polyurethane resin are free from styrene.
