The testing scope covers insulating tapes made of various materials, including PVC, electrical, rubber, polyimide, and fluoroplastics.
Core testing parameters include electrical properties (such as insulation resistance and breakdown voltage), mechanical properties (such as tensile strength and peel strength), environmental resistance (such as temperature resistance and weather resistance), and flame retardancy.
Specific testing methods include visual inspection, dielectric strength testing, 180° peel strength testing, holding power testing, flame retardancy testing (according to UL 510 or UL 94 standards), and high and low temperature testing.
Commonly used testing instruments include insulation resistance testers, dielectric strength testers, universal testing machines, high and low temperature alternating test chambers, and oxygen index testers.
