However, when it comes to purchasing it, it is important to know what to look for in order to ensure you are getting the best quality polyimide tape. Here, we will provide a few guides and methods on how to buy polyimide tape. By following these steps, you can make an informed purchase decision.

Buy BEST Polyimide Tapes

Polyimide tape, also known as Kapton tape, PI tape, or gold finger tape, takes polyimide film as the substrate, single-sided coated with high-performance silicone pressure-sensitive adhesive. There are single-sided fluoroplastic release material composite or not composite two types of materials. Generally, the coating precision of polyimide tape is up to ± 2.5um. It features no scratches, drawing and other phenomena, good shear, easy for die cutting. It has excellent high temperature resistance and solvent resistance. The storage conditions for polyimide tape are 10-30 ℃, relative humidity 40-70%; avoid direct sunlight and high temperature (more than 40 ℃) and high humidity (75% RH) environment.

How to Judge the Quality of Heat Resistant Polyimide Tape

With the increasing demand for high temperature tape, gold finger high temperature tape manufacturers have sprung up. The number of manufacturers around the world is increasing, resulting in the quality of gold finger high temperature tape sold on the market is also uncertain, so how to identify a real high quality polyimide tape. The following summary of a few methods can teach you to identify the authenticity of gold finger high temperature tape.

Evaluate Specification and Temperature Resistance

Before buying polyimide tape, it is important to consider its specifications, including base materials, adhesive strength, thickness, temperature resistance, and other characteristics. If you are not sure about its quality before placing the order, you can just ask your supplier to send you one roll of polyimide tape as sample for testing. Check below methods to test polyimide tape.

  • Method 1: Materials

Polyimide tape (Goldfinger high temperature tape) is mainly composed of two main parts: the base material and adhesive. If it is a fake high temperature kapton tape, whether the temperature resistance or insulation performance are far below the real gold finger high temperature tape.

  • Method 2: Smell

If the smell of gold finger high-temperature tape is very strong, and accompanied by a sour smell, then this gold finger high-temperature tape is very likely to be fake, and its adhesion and holding power will be very poor.

  • Method 3: High temperature test

The actual high temperature test of gold finger high temperature tape, after the high temperature, check the peeling force, whether there is residual glue, shrinkage and other phenomena. Because the temperature resistance of the real gold finger high temperature tape is usually between 120 degrees and 260 degrees.

  • Method 4: Look at the appearance

Look at the brightness of the surface of the gold finger high temperature tape, in general, the color of poor quality high temperature tape are a little dark, and the probability of fracture is very high, poor strength. On the contrary, good quality gold finger high temperature tape, the surface gloss are better.

  • Method 5: Look at the residue after burning

You can first use a lighter for 1 to 2 seconds, and then feel it by hand. If the ordinary, after burning with your hand, the glue will stick to your hand, if it is a real gold finger high temperature tape, there will be no glue stick to your hand.

  • Method 6: Material testing

When testing, look at the description of the gold finger high temperature tape. Because of the different types, some gold finger high temperature tape is as strong as the stickiness after high temperature resistance, some are in the high temperature resistance after tearing down without leaving residual glue, some are not deformed after high temperature resistance, so the specific still depends on what kind of tape you have.

Compare Prices of Different Polyimide Tape Supplier

Price is always a key factor when making the buying decisions for polyimide tape. It's important to compare prices from different vendors to ensure you're getting the best deal. However, some supplier may offer lower prices, but their tapes may not be as high quality as the ones from more expensive vendors. Therefore, when comparing prices, it's important to consider the quality of the tape you're buying.

Research Polyimide Tape Manufacturer

When sourcing a reliable polyimide tape manufacturer, it is important to research the manufacturer and verify their reputation, certifications, and reviews. You can search for the manufacturer's website and check their production capability. Make sure to check for any certifications the manufacturer may have such as ISO 9001, CE, and ROHS. Additionally, look for reviews of the product from other customers to get a better understanding of their customer service and quality of their products. You can also inquire about their production process and quality control standards. Additionally, check if the company is willing to provide any sample pieces of their polyimide tape for you to inspect. 

Ensure to Buy Polyimide Tape for Your Applications

The base materialof polyimide tape has acrylic, rubber, and vinyl. Each of these materials has its own advantages and disadvantages, so it is important to make sure you are choosing the right polyimide tape for your applications.
