Residential heat insulator that can achieve both heat insulation and incombustibility


Recently, the demand for heat insulation materials has increased because of increasing interest in energy saving at residences; the demand for heat insulators for residences that can achieve both heat insulation and incombustibility has also increased due to frequent large-scale fires. We developed THERMAX SW-G to respond to this demand. THERMAX SW-G is a rigid polyisocyanurate (PIR) foam board that prevents fire from entering inside due to a surface char layer formed by the isocyanurate structure; THERMAX SW-G has extremely high incombustibility even when burning on a burner at the temperature of 1200°C for 5 minutes as well as excellent thermal insulation performance.

Interior finishing material with strength and weight reduction

Foam injection lightweight deck box

The deck is placed on both sides of the automobile luggage area and the part where the tool kit for repairing flat tires and other tools are stored. This was an injection molded article previously made of normal resin, but we now use a resin material containing a chemical foaming agent and have reduced the weight by approximately ten percent while retaining the same strength with the high foaming method by opening the mold a little after filling gas generated by the heat inside the cylinder in the mold. The foaming type usually needs coating due to surface design, but this product does not need any coating and has the same level of design, contributing to improving the operation environment at production.


Special resin material using clean supercritical foaming technique


TURBOFLEXⅡ is a special resin material with low specific gravity and high impact resilience that is manufactured by supercritical injection foam molding without any chemical foaming agents that generate harmful gas. The material is used for the midsole heel of high-performance sport shoes. For example, this material is used for SKY MID/SKY LO volleyball shoes manufactured by DESCENTE LTD. and some players in the V Premier League use these shoes.

Composite with excellence in heat insulation, processability and flexibility

Flexible aerogel

Aerogel is a dried porous gel with low density and high porosity, which is notably weak as a simple substance. Therefore, impregnating a nonwoven fabric base material with it or the like is required for commercialization, as a heat insulation material, due to weak points such as gel falling (powder falling) during use and insufficient heat insulation. Aerogel becomes an excellent product featuring extremely rare powder falling, high heat insulation, processability and flexibility by making a composite (filling in cell) with a special foamed body with a skin layer having a fine cell structure. Aerogel is expected to be utilized in various fields such as automobiles and construction materials in the future.

Low-VOC, heat insulation and light shielding sheet


PureCell "CELL SHADE" is a heat insulation and light shielding sheet made from the low-VOC and eco-friendly foam material PureCell. It excels in thermal resistance and light stability, and has self-adhesive and shock absorption properties as well. With these properties utilized, the surface strength of CELL SHADE is enhanced further by being laminated with PET film. It provides heat insulation and light shielding from outside air if put on window glasses, and therefore has an effect on indoor temperature control (thermal insulation).

Developed version of 'U-Poly Pipe' that utilizes natural energy

Spiral heat exchanger for geothermal heat

Heat Exchange Equipment That Utilizes Geothermal System is a system that performs air conditioning and snow melting by utilizing stable heat (approximately 15 centi degree) 10 m to 100 m underground. "U-Poly Pipe" is a system used for air conditioning by exchanging liquid in the pipes installed underground with geothermal heat. The system utilizes natural energy, and thereby achieves low-consumption power.

Implementation at the same time as pile construction shortens construction period

Buried Work Condition

Further, the "Spiral Heat Exchange Equipment" which was developed based on the "U-Poly Pipe" shortens construction periods and reduces cost through the installation of spiral underground tubes when pile-driving, a part of foundation work, is done. The amount of heat exchange per depth unit of spiral tube is approximately three times greater than when using conventional U-Poly Pipe. The efficiency of heat dissipation and collecting is drastically improved.

Comparison of Heat Exchange Performance

Heat exchange amount 3 times. Increase heat dissipation and heat extraction efficiency


Thermal insulation and sound absorption improved with dual structure

Twin Composite Duct

A cylindrical duct that conducts air that is generated from the air conditioner of an automobile to the inside of vehicle's passenger compartment (the air blow-off port). Conventionally, a polyethylene blow-molded product was used. However, to meet the demand for improved fuel efficiency, a further decrease in weight and improved thermal insulation were required. We developed the "Twin Composite Duct," structured with double layers consisting of fiber and foam. The weight dropped to approximately half of that of the conventional product, thermal insulation improved to approximately 60%, sound absorption improved to reduce blower noise from the air conditioner, and further, dropping of dew condensation was reduced.

Development item: Twin composite duct. fiber + Firing PF 2 layer sheet.Weight reduction: Down by about 50% compared with the current level.

Eco-friendly with no chemical foaming agent used

FOLEC Double-sided Tape

FOLEC is a micro-celled clean roll-sheet product manufactured by INOAC's original foaming technology without using a chemical foaming agent. FOLEC Double-sided Tape is produced using FOLEC as the base material, and therefore provides excellent dust-proofing, water-proofing, and shock absorption. It will lead to a reduction of the chemical substances used and never breed* chemicals even when used for a long period of time, because it does not contain a chemical foaming agent.

*Breed: phenomenon of chemical substances oozing out to the surface.

No use of chemical substances. VOC Generation amount 132ppm.
Use to vibration proof / sound proof of construction heavy machinery. Control 10dB Driving amplitude.


Anti-vibration mat


CELLDAMPER is a foamed polyurethane elastomer developed for use as an anti-vibration material to reduce oscillation. It provides excellent anti-vibration, and its production process includes no silicone or sulfur. It is a clean product with a low environmental load. Among other things, CELLDAMPER is an eco-friendly anti-vibration mat. Large-scale construction generates diverse types of oscillation that continue for a long period of time, which is likely to be an annoyance to others in the neighborhood. Accordingly, countermeasures against noise or vibration source should be taken at construction sites by improving heavy machinery and reducing noise, among other things. The CELLDAMPER mat effectively reduces oscillation just by spreading it out under iron plates at the site. It can reduce running vibration caused by heavy machine by 10 dB. This product is used as anti-vibration material on heliports, roof-top decks, and so on, as well as with equipment and automobiles that generate oscillation.
