Product Description
Polypropylene is a relatively low temperature fiber with quite excellent chemical resistance which finds use in specialist applications such as the chemical industry.
The fibers cannot hydrolyse, the only chemical weakness being a susceptibility to oxidising agents. Other than that they can be used almost universally provided the temperature is below 90°C.The fiber is of a low density (it floats in water) and so a given denier of fiber is much larger in diameter than the polyester equivalent. This leads to felts being quite thick, almost 50% thicker than for the same polyester weight.The fiber is very prone to static build up so the felts are often augmented by the incorporation of either conductive fibers or a conductive scrim or a combination of the two. This then helps to dissipate potential static electric discharges.
