ESG Environmental Report

The TATSUTA Group is developing environmentally-friendly products. Through the business activities of
Tatsuta Environmental Analysis Center, we also work to reduce substances that burden the environment.

  • Wire and cable business

    We develop products with attention to safety, flame-resistance and low-fuming, as well as environmental compatibility such as recyclability.

    Safety Containing no halogens such as chlorine, these materials emit no dioxins or toxic gases when burned.
    Flame-resistant and low-fuming These materials are not only flame-resistant but also emit little smoke when burned, ensuring safety in the case of fire.
    Recyclable These products can be recycled through material recycling or thermal recycling.
    Chemical-resistant The use of polyethylene-based insulators provides outstanding chemical-resistant properties.
    Eco-friendly electric wire and cable

    When electric wires and cables are disposed of, their coatings mostly end up as industrial waste. In particular, there is concern over the impact on the environment of harmful substances released by vinyl chloride coatings when they are incinerated. Eco-friendly electric wires and cables boast the same level of fire resistance as conventional vinyl chloride-coated products but utilize highly-recyclable coatings and contain no halogen elements, lead, or other heavy metals.

      • かるまげ™ (Karu Mage) (KM-CC) 600V fire-resistant flexible crosslinked polyethylene eco-friendly cable

        These environmentally-friendly electric wires and cables are halogen-free and maintain a smoke density of 150 or less. Featuring outstanding flexibility, they reduce the workload of wiring in narrow places. They include no substances under RoHS (10 substances).

      • EM-TLFC110 eco-friendly fire-resistant flexible crosslinked polyethylene insulated electric wire, heat-resistant to 110℃

        This product features outstanding heat tolerance and flexibility. EM-TLFC110 uses eco-friendly, fire-resistant, crosslinked polyethylene material. By making the size of conductor smaller, it enables a reduction in the amount of copper and insulation material used. It includes no substances under RoHS (10 substances).

      • New Slat Cable

        This product uses “black crosslinked polyethylene” insulator, which features outstanding weather-resistance, instead of the vinyl material commonly used in the past. Excellent heat-resistance when applying electricity enables the cable to be down-sized. It includes no substances under RoHS (10 substances).

      • Electric wires and cables that contribute to reducing environmental impact

        This product features insulating material with an increased heat-resistant temperature. With a high allowable current capacity, it has a smaller conductor, enabling reductions in the amounts of copper and insulator material used. It includes no substances under RoHS (10 substances).

      • GT-Lead high-durability lead wire for plating barrels

        More than twice as durable as previous products due to the use of a special urethane in the protective layer (compared in-house). This product reduces the frequency of production line stoppages to replace lead lines, enabling productivity enhancements and total cost reductions. Outstanding flexibility has also been achieved through the use of a flexible-type conductor, resulting in higher workability. It includes no substances under RoHS (10 substances).

      • Thin-diameter KORIKI™ high-strength cables

        Outstanding flex durability enables wiring space reductions, as well as flexible wiring and layout. This product contributes to lighter, more compact and space-saving industrial equipment, robots, etc.

      • Rubber cabtire cables

        Manufactured using a “lead-free vulcanization method,” these are environmentally-friendly cables that fully comply with RoHS and REACH regulations. The tandem extrusion of rubber sheaths and lead-free vulcanization material realizes shorter production processes, leading to a reduction in production energy consumption and workload.

      • Detecting substances that burden the environment

        This sensor complies with regular inspections of places that cannot be inspected visually, which are required under the Water Pollution Prevention Act. It enables users to detect the position of sulfuric acid, hydrochloric acid, nitric acid, and other substances. It can be installed on existing equipment or outside.

  • Electronic materials & system equipment business

    We develop products with attention to environmental compatibility, including compliance with standards such as halogen-free, Restriction of the Use of Certain Hazardous Substances (RoHS), UL, etc.

    Halogen-free Containing no halogens such as chlorine, these materials emit no dioxins or toxic gases when burned.
    RoHS-compliant Containing no lead, cadmium, mercury, hexavalent chromium, the designated bromine-based flame retardants polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), or four phthalates, which are designated hazardous substances that have a negative impact on the environment and human body. It is also compatible with reflow processing using lead-free solder.
    Meeting UL standards UL94 is a United States flammability testing standard. VTM-0 tests the vertical flammability of thin plastics, and V-0 tests vertical flammability. TATSUTA has developed products that have attained UL94 flammability class VTM-0, to provide products featuring outstanding safety and flame-resistance.
      • SF-HR5600-C highly heat-resistant shielding film for automobile applications

        This high heat resistance shielding film can be used even in harsh environments. While maintaining the structure of previous general-purpose electromagnetic interference (EMI) shielding film (SF-PC5600-C), this product achieves superior durability, withstanding 2,000 hours of continuous use in high-humidity high-temperature environments (85℃ at 85% humidity) and high-temperature environments (125℃). It is considered increasingly for possible use in in-vehicle displays and printed circuit boards for automotive sensors, cameras, headlights, etc. It has attained UL94 flammability class VTM-0. It is also halogen-free and complies with RoHS.

      • Via filling paste (metalizing type) (MPA500)

        This connecting material maintains a connection reliability equivalent to solder (treated at a temperature of 240℃ or above), and enables low-temperature hardening at 180℃ or below. It is used as an interlayer connection in semiconductor inspection substrates and high-speed telecommunication substrates for 5G. Moreover, as an alloy is formed after metalizing, it features high heat resistance, with a melting point of 300℃ or above. Using MPA500 instead of conventional electroplating as an interlayer connection enables a 40% reduction in CO2 emissions from printed circuit board manufacturing processes. It is also halogen-free and complies with RoHS.
