Technology information

High-performance inside seal

A high-performance inner weather strip that is lightweight and highly resistant to wiping off glass fog using materials developed using resin foaming technology and water-absorbing fabric.

Stable foaming technology using thermally expandable capsules
Achieved weight reduction of resin core material by 30% (compared to conventional model)

・Improved sagging resistance by 11% Glass seal lip material and water-absorbing fabric make it easier to wipe away glass fog.

　* Our experiment shows that the amount of water droplets left behind when raising and lowering the glass has been reduced by 50% compared to conventional methods.

High performance glass run

Glass run with improved noise resistance and glass flapping resistance that reduces deterioration over time.

Achieving high performance with three new technologies (shape design, lip material, and high-performance sliding material)

・Anti-sagging performance improved by approximately 40% compared to conventional products, top class among TPV glass runs.

・Glass sliding resistance after durability test, an indicator of noise performance, has been improved by 30% (compared to our company’s comparison).

High-performance partition

Partition W/S that achieves a high level of improved vehicle assembly, scratch resistance, and weight reduction.

Developing new materials using special fillers and material compound technology (patented technology)

・Improves workability by reducing vehicle assembly force and improves adhesion with panels and surrounding parts. Low friction + lightweight, assembly force reduced by 40% (compared to our company).

・Due to the effect of special filler, it has better scratch resistance than PVC material. Prevents scratches during assembly work and ensures high quality design when using parts.

　* PVC = vinyl chloride material, generally has excellent scratch resistance

TPV sponge sub seal

High appearance and high durability TPV sponge as an alternative to vulcanized rubber sponge​.

Achieved by foaming low-hardness materials using TPV foaming technology and using materials with good appearance and multilayer extrusion technology

・Recyclable TPV and energy reduction during parts production (-60% compared to our company), reducing environmental impact.

・Achieved prevention of release sound and high design (prevention of whitening) to improve defects in rubber sponge material.

High heat resistant BUSH

BUSH using anti-vibration material with significantly improved heat resistance.

Through rubber material compounding technology and product design technology, we have achieved approximately three times the heat resistance compared to conventional materials (compared to our company).

・BUSH has anti-vibration characteristics that do not change over a long period of time, achieving performance that does not change the riding comfort over time.

Made of high heat resistant EPDM EXH/MTG

General-purpose rubber: EXH MTG, which is made of EPDM and is extremely heat resistant.

Achieved through the synergy of applying heat-resistant material technology for brake cups and design and manufacturing technology for vibration-proof parts.

・A general-purpose rubber that can withstand extremely high temperatures of 150°C or higher, which were traditionally the domain of special rubbers: By designing with EPDM, it offers higher anti-vibration properties and cost competitiveness than special rubbers.

High electrical resistance water hose

Increasing needs for BEV/HEV cooling hoses: Hose compatible with high electrical resistance specifications.

Realizing a water-based hose with high electrical resistance using rubber material compounding technology and hose manufacturing technology (patented technology)

・Provides highly functional hoses with improved corrosion resistance and lighter weight (compared to conventional models: no increase in mass) due to high electrical resistance.

Super heat resistant water hose

General-purpose rubber: Cooling hose made of EPDM that can withstand temperatures of 150°C or higher.

By optimizing the rubber material compounding technology and reinforcing threads, we have achieved a super heat-resistant cooling hose (2.5 times higher than our company’s)

・A lineup of general-purpose cooling hoses ranging from 100℃ to super heat-resistant specifications of 150℃ and above to meet the various needs of our customers.

Ultra pressure resistant water hose

Cooling piping rubber hose that meets the required specifications for high pressure resistance .(fastening seal performance)

A pressure-resistant hose is realized by optimizing the type of reinforcing yarn and the weave angle, and combining materials that achieve pressure-resistant performance.

・For cooling system piping hoses, the pressure resistance is approximately twice as high as that of conventional products, without compromising the insertion process using optimized reinforcing threads.
