Heat-resistant tape 5505HR & 5503HT

-Challenge- Thermal durability of the product fixing around a heat source.

As the size and weight of automotive electronic components are becoming increasingly compact and lightweight to achieve lower fuel consumption and EVs in automobiles, the heat generation density of the components themselves is increasing, creating a need for higher heat resistance in the adhesive tapes that hold them in place.

-Solution- Excellent high heat resistance tape with low VOC

High heat-resistant tapes are for attaching automobile interior components, featuring high heat resistance up to 180°C and reduced VOC (reduced odor) with our proprietary compounding technology.　
This adhesive maintains some level of softness at room temperature, while keeping the firmness when exposed to high temperatures, making it ideal for attaching materials related to electronic components, which will be increasingly in demand for electric vehicles (EVs) going forward.
Besides, silicone adhesives are currently often used in high temperature areas and may contain 13 VOC substances. Our "High heat-resistant transfer tape 5503HT・5505HR" can be used as an alternative material.

-Technology- Technology information

Technical overview

High heat resistance up to 180°C
by our proprietary technology

Retains adhesiveness at high temperatures
with our proprietary precision blending technology

Nomally, when heated, it softens and loses adhesiveness, but our proprietary technology overcomes this problem.
Can be used on high heat parts such as heaters.

Low-VOC has less impact for
environment and humans

Low VOC (odor)
for a comfortable interior

VOC (volatile organic compounds) have
been significantly reduced to one-fifth
of conventional products.

Heat-resistant enough not to cause misalignment even at 180°C

Normally, thinner adhesion lowers adhesion, but our proprietary technology has achieved both adhesion to rough surfaces and high heat resistance at a thinness of 30 μm.
We expect that this product will be used in future EV models.

Adhesion to rough surfaces
under high temperature

It adheres to fabrics and foams, which are generally difficult to adhere to due to their uneven surfaces, and retains its adhesive strength even under high temperatures.
