Petrorays brings High quality Cast Nylon rods Round & square profile. CAST NYLON is far superior to extruded Nylon-6.
Cast Nylon is made bydirectpolymerization of caprolactam, this polymer is never been melted and thus it is not subjected to any thermal degradation. We are manufacturers, suppliers, and exporters of cast nylon rods and sheets in Mumbai, India to all over the world.
In addition, its molecularweight is several folds higher than molecular weight of Extruded Nylon-6.
With Increase in molecular weight the physical properties of Thermoplastics improves Cast Nylon has superior tensile & compressive strength, modulus of elasticity, better wear & tear resistance, Lowerdistortion even at Higher temperatures, Low moisture absorption, superior dimensional stability
