We offer a wide range of pultrusion products for the Pultrusion process. Pultrusion is a continuous, automated closed-moulding process that is cost effective for high volume production of constant cross section parts. The basic process usually involves pulling of continuous fibers through a bath of resin, blended with a catalyst and then into pre-forming fixtures where the section is partially pre-shaped & excess resin is removed. It is then passed through a heated die, which determines the sectional geometry and finish of the final product.

 

Due to uniformity of cross-section, resin dispersion, fiber distribution & alignment, excellent composite structural materials can be fabricated by pultrusion. The profiles produced with this process can compete with traditional metal profiles made of steel & aluminium for strength & weight.

 

By using various additives, liquid resin systems can be made suitable to provide specific performance. Alumina trihydrate is filler that is used for its ability to suppress flame and smoke generation. Special purpose additives include ultraviolet radiation screens for improved weatherability, antimony oxide for flame retardance, pigments for coloration, and low-profile agents for surface smoothness and crack suppression characteristics.
