● Physical data in the above table is for reference only.
● Vulcanization condition: 175℃*5Min.
● Ratio of curing agent liquid 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane: 0.65%.
●The supplied test report is obtained by the Quality Inspection Department with the curing conditions and testing
method of the company; due to the difference of curing conditions and testing method, we can’t guarantee that both
parties obtain the same testing result, and we suggest that users should use the test data obtained under their own testing
conditions as the reference for service performance. All the above performance data and application recommendations
are only a reference for use on the service performance of product, instead of a guarantee on the effectiveness or general
applicability of our products under a certain application.
