Yellowing Resistance Chamber|UV Light Discoloration Tester HTE-008 China Factory
UV Light Discoloration Tester HTE-008
This machine is specially designed to measure the yellowing resistance of white or light-colored shoe materials such as upper materials, substrates, leather, PU, fabrics, etc., under light irradiation. It uses a sunlight bulb and a heating temperature control device to irradiate the test sample, testing the sample’s ability to resist yellowing under sunlight. It is suitable for arbitration, precision scientific research, and development work.
