● 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.
