High heat resistance PI masking tape is a polyimide based silicone PSA tape with high heat resistance and excellent insulation effect. The product is featured with great adhesion (500gf/in) laminated with fluorosilicone release liner and can be supplied as die cut. It’s red in color, suitable for insulation finishing work & High temperature masking & PCB HAL process. Masking tape, also known as painter’s tape, is a type of pressure-sensitive tape made of a thin and easy-to-tear paper, and an easily released pressure-sensitive adhesive. It is available in a variety of widths. It is used mainly in painting, to mask off areas that should not be painted. The adhesive is the key element to its usefulness, as it allows the tape to be easily removed without leaving residue or damaging the surface to which it is applied. The tape is available in several strengths, rated on a 1–100 scale based on the strength of the adhesive. Most painting operations will require a tape in the 50 range. Household masking tape is made of an even weaker paper and lower-grade adhesive. Pi Tape gages consist of a narrow metal ribbon bearing special graduations. These graduations are designed to convert circumferential distance into diameter measurement so the observer can read the diameter directly from the scale. Heat resistance tape are the tapes which are not burned or melted at any degree of temperature. Heat Resistant Tape has a strong adhesive bond and is highly resistant to shock. High Heat Resistant tape is essential for electrical insulation, cable terminations, and splicing in high-heat applications. This is because tape products that are not specifically designed for this purpose will rapidly lose adhesion, potentially resulting in hazardous conditions. We can use heat resistant tapes where normal tapes will not work properly due high pressure and temperature. They also have low shrinking characteristic due to low coefficient of expansion. Various heat resistant tapes are available for specialty projects like high bulk glass fiber tapes that have a heavy coating of iron oxide and red silicon rubber. Heat resistant tapes are manufactured with varying width, length, thickness, and color; therefore you get high flexibility for purchasing the tape according to your requirement. They can tolerate temperatures up to 1650° C.
