ESD black leader tape
The black anti-static PET guide tape is made of DuPont Hongji polyester film (PET), which is a thin film material made from polyethylene terephthalate as raw material, extruded into thick sheets, and then biaxially stretched. Meanwhile, it is a type of polymer plastic film that is increasingly favored by consumers due to its excellent comprehensive performance. It is a black glossy film with excellent mechanical properties, rigidity, high hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, airtightness, and good fragrance retention. It is one of the commonly used composite film substrates for anti-static properties. After surface treatment with polymer raw materials, it becomes a multi-purpose film for anti-static purposes.
