Polyurethane cord is a type of cord that offers superior seal performance in hydraulic situations where high pressures, shock loads, or abrasive contamination is anticipated.
It has chemical compatibility similar to that of Nitrile, offering good resistance to petroleum-based oils, hydrocarbon fuels, and hydraulic fluids, the oxidizing effects of ozone, and the aging effects of sunlight.
Polyurethane cord is tough and durable with exceptional abrasion resistance and has excellent oil and chemical resistance and a high coefficient of friction.
However, unless specially compounded, at elevated temperatures, polyurethane cord begins to soften, losing its physical strength and chemical resistance advantages over other polymers. The solid cord of
polyurethane has a tendency to rapid deterioration when exposed to concentrated acids, ketones, esters, chlorinated, and nitro hydrocarbons.
It also prone to hot water and steam degradation. We offer a range of extruded transmission drive belting including cords, tubes, and V profile and special profile extrusion. We can also manufacture endless polyurethane drive bands using in-house welding facilities.
