Development of Elastomers Having Low Water-Vapor Transmission Rate.

Abstract

The effect of various types of fillers on the water vapor transmission rate (WVTR) of vulcanizates of EPR was determined. Carbon black and most nonblack fillers produced only a small reduction in the WVTR, whereas platelike mica fillers produced significant reductions. High-density polyethylene reduced the WVTR, but physical properties were adversely effected. EPR/butyl rubber blends containing 50 pphr of carbon black produced vulcanizates with good physical properties and low permeability to moisture. (Author, modified-PL)
