METHOD FOR DETERMINING RELATIVE SPECIFIC GRAVITY POLYTETRAFLUOROETHYLENE TUBING
This specification describes a method for determining the specific gravity of tubing, fabricated from polytetrafluoroethylene, after a controlled heating and cooling cycle. The specific gravity obtained by this method is a measure of relative molecular weight of the resin. The measure, termed Relative Specific Gravity (RSG), increases with decreasing molecular weight (see 2.3).
