Testing of Polymer Materials

CTI has a variety of physical testing capabilities for polymer materials, including density, hardness, tensile, bending, impact, compression, DSC, TGA, melt flow rate, brittleness temperature, temperature of deflection under load, Vicat softening temperature, ash content, flammability, high temperature aging, low temperature aging and xenon-arc weathering tests. The testing methods meet the international standards (ISO), national standards (GB) and other tests according to the standard requirements of OEMs, the test objects includes PC, ABS, PP, PE, LDPE and HDPE.
Service cycle: 7-10 working days (Aging test depends on the specific test time).

◉ Service Background

In today's society, automobile has become an indispensable tool for modern people's life. As the basis of vehicle production, the quality of automobile materials is directly related to the success of the vehicle. CTI, as an internationally recognized inspection, identification, testing and certification organization, test various physical properties of various polymer materials for car body, including mechanical properties, thermal properties and optical properties. These performance parameters are an important part of the whole material quality.
