Excellent Pultrusion Processability – Exhibits a low-to-moderate viscosity and tailored reactivity profile (short gel time) for high-speed, consistent pultrusion, ensuring uniform resin impregnation and low void content.
High Heat Distortion Temperature (HDT) – Maintains dimensional stability and mechanical strength during and after the pultrusion curing process, and withstands elevated temperatures in harsh operating environments.
Corrosion & Chemical Resistance – Offers robust protection against moisture, water ingress, and common corrosive elements, ensuring a cable life expectancy of 25+ years.
Dielectric Properties – As a non-conductive polymer, it ensures the finished FRP rod is free from electromagnetic induction and is safe for use near high-voltage lines.
Low Cure Shrinkage – Minimizes internal stresses during curing, which is critical for maintaining the tight dimensional tolerances required for the central strength membe
