METHOD AND APPARATUS FOR DETERMINING MELT ELASTICITY
摘要
An apparatus and method for determining the standardized melt elasticity (sME) force of a thermoplastic polymer needed to stretch a strand of melted polymer at a speed about thirty three times faster than the speed of strand formation from a body of melted polymer under constant stress from an unencumbered dead weighted piston.
