Notice Concerning the Release of the World’s First Transfer Tape with High Heat Resistance, Thin-film, Low VOC, and Adhesion to Rough Surfaces
5503HT 
5505HR
SEKISUI CHEMICAL CO., LTD. is pleased to announce that its High Performance Plastics Company will release the world’s first industrial double-faced tapes, “High heat-resistant transfer tape 5503HT・5505HR,” on March 20, which feature four characteristics: high heat resistance, thin film, low VOCs, and high adhesion to rough surfaces.
*VOC (Volatile Organic Compounds)
*World's first：According to our research in 2023 Feb.
Background of the development
As environmental awareness grows worldwide, the shift from gasoline (diesel) cars to electric vehicles is further accelerating in many countries and regions. The replacement of an engine with an electric motor as the vehicle’s power source has caused problems such as securing a heat source for heating (Engine cars use engine cooling water as a heat source for heating.) and narrower spaces due to an increase in electrical components mounted on the vehicle body. The challenges are to improve “heat management efficiency associated with EVs” and to increase the “degree of freedom in vehicle interior design.”
SEKISUI CHEMICAL has been working to solve these problems for vehicle applications and has now succeeded in developing new high heat-resistant transfer tapes (base material-less tapes) that have high thermal efficiency and can directly fix protective fabrics to in-vehicle heaters.
There are four problems to be solved when fixing the protective fabric to the radiant heater installed near the passenger’s seat: (1) withstanding high temperatures, (2) being as thin as possible to reduce its thermal capacity, (3) ensuring stable adhesion to rough and uneven surfaces to cloth, and (4) being low VOC enough to be used for interior materials.
The tapes can solve the four problems with SEKISUI CHEMICAL’s proprietary adhesion and polymer polymerization technologies.
