What will affect the effect of high temperature tape? Classification and application of high temperature tape

by:Yourijiu     2021-08-06
Adhesives such as high-temperature tapes and tear-off tapes have a peel strength. The peel strength will more or less affect the effect of the tape produced. The strength can be determined by the peel strength test.

Peel strength is also called peel strength. The peel test is to measure the ability of the bonded joint to bear the line force, and its strength is expressed by the maximum breaking load that the bonding surface can withstand per unit width. Peel strength can be a measure of the ability of a bonded joint to resist crack propagation. The peel test is to tear a flexible part of the assembly bonded by the adhesive tape from another flexible or rigid part that is bonded to it. Because the adherend is relatively thin, when the external force acts, the flexible part of the adherend first undergoes plastic deformation, and then the adherend will slowly and continuously tear. For example, fabric-bonded fabric or fabric-bonded metal can be peeled off.

1. Classification of high-temperature tapes

High-temperature tapes include KAPTON high-temperature tape; Teflon high-temperature tape; high-temperature masking tape; high-temperature protective tape; PET green high-temperature tape; high-temperature double-sided tape, etc.

2. Masking tape

1. The masking tape uses imported white masking paper as the base material and is coated with weather-resistant rubber pressure sensitive adhesive on one side. to make. It has excellent properties such as high temperature resistance, solvent resistance, and no residual glue after peeling! Products meet ROHS environmental protection requirements.

2. Masking tape characteristics: good adhesion, good extensibility, no breakage, temperature resistance of 60℃-350℃, width of 2mm-800mm, length of 10y-500m, etc. to choose from. Solvent resistant, no glue residue.

3. It is suitable for baking varnish masking protection, capacitors and various electronic parts assembly processes. Automotive and plastic hardware, spray painting and general coating mask processing, PCB board fixing drilling, wave soldering, and protection during reflow soldering.

4, the thickness of the tape is 0.14~0.20mm, white or light yellow, suitable for high-temperature baking paint and spray paint masking protection on the surface of automobiles, iron or plastic devices, and also suitable for electronics, electrical appliances, and varistors. In industries such as circuit boards, the temperature resistance range is 80°C~260°C. Users can make the most suitable and economical choice according to the actual operating temperature of the production process.

Three. Use of high-temperature tape

High-temperature tape, which is an adhesive tape used in high-temperature operating environments. Mainly used in the electronics industry, the temperature resistance is usually between 120 degrees and 260 degrees. It is often used for spray painting, baking varnish leather processing, coating masking and fixing in the manufacturing process of electronic parts, printed circuit boards and high-temperature processing masks.
