Polypropylene,PP Needle Felt Filter Cloth

we are offering polypropylene,pp needle felt filter cloth. 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.
product feature
- smooth surface, more defined pore size and good air permeability
- low temperature resistance ( 88-110 )
- excellent resistant to hydrolysis, acids and alkalies.
- lower fiber release, lower density,high mechanical characteristics
