Abstract
Disclosed are porous elements that include sintered polymeric particles. The polymeric particles can be formed of a thermoplastic composition that includes a polyarylene sulfide. The polymeric particles sintered to form the porous elements have a very narrow size distribution. The porous elements can maintain their functionality and morphology even when utilized in high temperature applications.
Claims38
A porous element comprising sintered polymeric particles, the polymeric particles comprising a thermoplastic composition that includes a polyarylene sulfide and an impact modifier that includes an epoxy-functionalized olefin copolymer, the polymeric particles having a median particle size and a particle size distribution, the particle size distribution being such that 50% of the polymeric particles have a size between about 60% of the median particle size and about 140% of the median particle size, and such that 10% of the polymeric particles have a maximum particle diameter that is between about 35% and about 60% of the median particle size of the polymeric particles.
