What is the difference between Mara tape and PET high temperature adhesive

PET high temperature tape is commonly used in PET substrate tape,Marla tapeIt is also a PET substrate, but the price is much cheaper. mara tape and pet high temperature adhesive with what's the difference?

People who have just come into contact with high-temperature tape often see high-temperature tape of the same color, because the colors of PET high-temperature tape and Mara tape are very similar, and it is not clear what is the difference between high-temperature tape of different colors. It may often be unclear what is the difference between the two high-temperature adhesives, because their surface materials are all PET film types, the colors are the same, and they can withstand high temperatures. So what's the difference between the two?

First, let's briefly introduce what they have in common, that is, they are all made of PET film, which can be different colors, and the colors can also be the same. The differences are as follows:

1. temperature resistance:

1.PET high temperature tape can withstand a high temperature of 200 degrees for a long time, while Mara tape is different, its temperature can only withstand about 120 degrees. This is the temperature resistant environment is different.

2. To explain from their different structures, PET high temperature tape is coated with silicone rubber on PET, while Mara tape is coated with acrylic glue on PET. In this respect, it means that the mara tape can withstand higher temperatures than PET high temperature tape.

3.PET high temperature tape can be used for electronic PCB boards such as 200 ℃ baking and painting, while Mara tape is different. Mara tape is mainly used for insulation protection of transformers, motors and other electrical appliances.

Polyester high temperature tape is based on polyester film and coated with imported silicone rubber.

1. It has high temperature resistance, shape retention and solvent resistance

2. Uses: powder spraying, high temperature shielding, gold-plated protection. (Specially used for circuit board dipping paint process, covering gold finger parts, preventing immersion and pollution of electroplating solution, protecting circuit board electroplating, high-temperature baking paint, powder spraying and other industries), with excellent high temperature resistance, no glue residue, solvent resistance, even in welding, polishing, drying, electroplating and other harsh conditions can also be bonded, after use can peel off no glue residue. The tape has excellent acid and alkali resistance, electrical insulation, chemical resistance, high adhesion, softness and flexibility, and no residual adhesive after tearing

Mar.Tape (polyester insulation tape) is based on polyester film composite non-woven fabric as the substrate, coated with acrylic pressure-sensitive adhesive or rubber pressure-sensitive adhesive, has a strong high temperature resistance, voltage resistance performance, suitable for transformers, motors, capacitors and other electrical and electronic components of the insulation package, as well as the protection of high temperature resistant objects. 

PET high temperature tape andMarla tapeIn addition to the different temperature resistance, it is mainly coated with different glues on the surface of the substrate, which will bring about great changes in the use.
