Friend takes quality and reliability very seriously, it is for this reason we heavily invest in quality control. In fact, we have established a comprehensive testing center. Shown here is the state-of-the-art thermo-mechanical analyzer, manufactured by TA Instruments in the US, which tests the coefficient of thermal expansion of our insulation materials across a range of temperatures. Controlled by a microprocessor, the universal tester is used to test the tensile strength and compressive strength of our insulation products. To further ensure quality, we’ve introduced 18 test instruments in total, including the arc resistance testing machine, Q meter, impact tester, dielectric strength tester, and the open-back inclinable press.
