Notice of participation in the '2026 NAGOYA Automotive Technology Exhibition' from June 17 (Wednesday) to June 19 (Friday), 2026.

Starting from April 2023! Introducing a new model that enables 3D modeling with silicone rubber!

"SILICOM" is a product that expands the new possibilities of silicone rubber (silicon) 3D printing, utilizing a UV (ultraviolet) curing liquid layered manufacturing method (LAM method). It features excellent transparency and achieves a reduction in the layer marks characteristic of 3D printing. The material supply adopts a cartridge system, simplifying the setup for changes in hardness and other adjustments. With our proprietary slicing software, it is easy to perform printing simply by selecting the material, and further complex shapes can be created through cross-linking. 【Features】 ■ Stable supply and guarantee system through domestic production in Japan ■ A planned lineup of various hardness levels from low to high hardness ■ Excellent transparency ■ Achieves the removal of layer marks characteristic of 3D printing ■ Color tone compatibility is also possible ■ 100% silicone rubber *For more details, please refer to the PDF materials or feel free to contact us.

Non-halogenated, environmentally friendly flame-retardant elastomer foam equivalent to UL-94 V-0!

We have developed an "Eco Nannen Elastomer Sponge" that is highly flexible and does not contain halogens, using our unique compounding technology. Compared to conventional rubber-based flame-retardant sponges, the amount of carbon dioxide emissions during production can be significantly reduced. Additionally, being non-halogenated makes it suitable for electronics products and automotive products, which face stricter environmental regulations and flame-retardant standards in recent years, as well as for flame-retardant sponge tubes and pipes used in construction materials. We are currently making diligent efforts to further reduce hardness and develop irregular shapes. Samples are available for those who are interested. 【Features】 ■ Flame Retardancy: Has performance equivalent to V-0 in UL94 standard testing ■ Excellent Environmental Properties: A product that is environmentally friendly as it does not use RoHS regulated substances ■ Flexibility: Lightweight with a specific gravity of 0.57±0.2, offering excellent flexibility *For more details, please download the PDF or feel free to contact us.

Achieving electrostatic flocking equivalents at low cost.

"HP Flock" is a revolutionary extruded product that enables the electrostatic flocking process, which has been used in automotive weather strips and other applications, through a special processing method, allowing for cost reduction and improved environmental performance. Electrostatic flocking involves applying adhesive to the product and using static electricity to insert fibers into the product's surface, making it a labor-intensive process that can dirty the work environment and lead to increased costs due to secondary processing. Thanks to its unique processing method, this product eliminates the need for drying operations like those required in electrostatic flocking, allowing for cost savings. Additionally, by not using large amounts of solvents such as primers or adhesives during manufacturing, and by reducing drying processes, it can decrease CO2 emissions, making it possible to create products with lower environmental impact. The standard flock is made of nylon with a density of 3.3 dtex and a pile length of 0.5 mm, but other options for density, pile length, and material changes to polyester are also available. Moreover, the creation of colored products, multiple processing points on a single cross-section, and depending on the shape, molding with our special low-friction resin "Sube Up" is also possible. *For more details, please refer to the PDF document or feel free to contact us.*
