1. Basic Properties
Product Names: Black Imide Adhesive Tape, Black PI Tape, Polyimide Light-Shielding Tape, High-Temperature Insulation Shielding Tape, Electronic Anti-Static Fixing Tape Substrate: Imported black polyimide (PI) film substrate. The film surface is dense and uniform, matte, opaque, highly durable, and resistant to stretching without deformation. Adhesive type: Industrial-grade high-temperature resistant silicone pressure-sensitive adhesive, evenly applied on one side, with a fine layer and strong adhesion; does not flow or lose tack in high-temperature environments. Adhesiveness: Quick initial adhesion and stable retention, smooth and tight fit on precise surfaces; no curling, delamination, or residue glue under high-temperature conditions. Core features: ultra-high temperature resistance, full light-blocking, insulating and flame-resistant, anti-static, acid and alkali resistance, wear-resistant and anti-aging, precise bonding, no peeling at high temperatures Specs: a wide range of widths and lengths available in stock; standard matte black version, supporting precision slitting, special-shaped cutting, and custom production of large industrial rolls. Temperature resistance range: -20℃ to 260℃, with instantaneous resistance up to 300℃; remains intact, non-crusting, and unchanged in color under continuous high-temperature operation. Applicable processes: light shielding for electronic screens, high-temperature spraying shielding, circuit board insulation protection, battery mounting, precision electronics anti-static wrapping, industrial high-temperature protection
2. Core Advantages of the Product
1. Fully light-blocking and opaque; designed for precise shielding: Utilizes an integrated black matte PI substrate with no light-transmitting white spots or light-leaking gaps. The light-blocking effect is 100%, effectively solving issues such as light leakage from screen backlighting, light interference from device sources, and color contamination from spraying. Its shielding performance far exceeds ordinary brown amine tape. 2. Extremely high temperature resistance; suitable for industrial high-temperature conditions: the base polyimide substrate combined with a high-temperature resistant silicone adhesive layer can withstand continuous temperatures of 260°C for long periods. It does not leak glue, carbonize, or delaminate during reflow soldering, high-temperature spraying, and baking processes. It also does not crack in low-temperature environments, and its performance at both high and low temperatures is stable and excellent. 3. Insulation and anti-static properties, electronic protection and safety: The substrate possesses excellent insulation and anti-static characteristics, which can effectively block electrical currents and prevent static charge accumulation. It protects precision circuit boards, chips, and battery components from static damage, while also providing flame resistance and corrosion protection, making it suitable for high-end electronic precision protection applications. 4. The surface is smooth and flat; removal is seamless with no damage to the material: the film is ultra-thin and uniform, with good flexibility. It fits curved surfaces and edges without bulging, making it suitable for bonding small precision components. After the process, it can be easily removed without any residue or adhesive left behind, nor does it corrode the substrate surface. No additional cleaning is required, thereby improving production efficiency.
