The Blow-Point Analyzer is a testing equipment to measure cure time of rubber the minimum required and effective to control curing process of tire,belt and rubber vibration isolator.It is useful for improvement of product’s characteristics such is determined as improvement of productivity,energy saving,abrasion resistance and durability.
A thermal diffusion constant by measurement of a temperature in real-time during curing process by use of wedge-typed mold having a slope,then,an equivalent cure time and limiting degree of cure can be determined from an activation energy got in advance and a bubble limiting point at the intermal part of sample after cure.
