Rubber, vulcanized or thermoplastic. Determination of permeability to gases - Equal-pressure method1 Scope This document specifies a method for the determination of the gas transmission rate and gas permeability coefficient of vulcanized or thermoplastic rubber under conditions in which the overall pressure on each side of the rubber test piece is the same, using gas chromatography to determine the quantity of gas that permeates through the rubber. The method applies to vulcanized and thermoplastic rubbers of hardness not less than 35 IRHD

NOTE 4 The values tabled for locked rotor apparent power are based on r

Polymers with larger molecular sizes have a higher molecular weight which provides higher viscosity

It covers both thermoplastic and thermosetting polyester
