PP needle punched felt
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.
• 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 characteristic
