Pulex rubber is real vulcanized natural rubber (NR), which is compression molded, item by item, and must have consistent and homogeneous chemical and organic features. They process the raw material to obtain a mix with no impurities that guarantees the vital requisites of perfect molecular dispersion, cross linking, elasticity, snap, resilience, hardness, resistance to chemical and atmospheric agents, coloring and surface smoothness. This brings us to the third aspect, namely the perfection and linearity of the blade’s cleaning edge, which depends on the cut made by precision machines and scrupulous quality control.
Available in several factory cut sizes - HARD(for Summer months) and Soft(for Winter months)
