Processing technology 3 Resins for Composite Materials 〜Rigolac™, Ripoxy™〜 Product Example Our technologies Synthesis technology With a focus on unsaturated polyester resin, vinyl ester resin, and urethane-acrylic resin, we own resin synthetic technology meeting such requirements as flexibility, hardness, high strength, and high heat resistance. We can also develop new resin systems. Compounding technology Chemical tank FRP waterproofing While considering the final usage environment and purpose, we can propose usage methods such as compounding additives, including fillers, curing agents, and accelerators, while also drawing up construction specification proposals, for example. Physical property evaluation We can evaluate the basic properties of products and make various measurements while considering the actual usage conditions. Technical guidance Resin concrete Pipe lining To prevent troubles when the products are used, we can attend and provide technical guidance as required when the products are used. If any trouble arises, we will study countermeasures.

Product Example Application that utilize the biodegradability Our technologies of Binolle™ (PBS: polybutylene succinate), as well as its physical properties similar to Mulch films those of polyethylene. ■High molecular ■Degradability and weight products No need to collect the films after harvesting flexibility control Using our unique polymerization Degradability and flexibility can be technology, we successfully adjusted according to the application manufactured high molecular by selecting a raw material weight PBS. monomer and adjusting its Now, various products can be formulation. manufactured using a general machine for polyethylene. Four months later, films Improvement of have biodegraded into processability tatters. Alteration of the molecular Packaging materials structure makes it possible to (Plastic shopping bags, garbage bags, etc.) manufacture the grade suitable for foaming and In various countries, there are lamination process. restrictions on the use of non- biodegradable single-use bags to protect the environment.
Long-branched structure ™ Bionolle™ has been authorized Bionolle 1903MD the international certifications that prove its biodegradability. ■ Blending with starch and polylactic acid We have established technology to blend starch in a high Biodegradability in compost concentration (>30wt%). We named the product STARCLA™. It is not necessary to separate kitchen garbage and garbage The biomass ratio not only reduces the cost, but also increases bags in composting facilities. the tear strength significantly. Of course, the bags also degrade in nature. The biomass feedstock, polylactic acid, which is poor in flexibility, brittle, and hard to mold, as blended with Bionolle™, and established the compound showing good moldability and 1 week later 2 weeks later 3 weeks later 4 weeks later physical properties. We named the product KIYOYUKI™ 6 Solder Mask for Flexible Board
