Abstract:
A composite polymeric material is provided that may be used to construct an abrasion resistant layer or sheet such as an abrasion resistant meltblown layer. Desirably, the composite polymeric material comprises blends of syndiotactic and isotactic polypropylene with ferroelectric materials. The composite polymeric material is particularly useful for constructing a filter media comprising an abrasion resistant fine fiber layer such as a nonwoven layer. The composite polymeric material of the present invention also allows for electret treatment to improve its filtration characteristics.
