井上石灰工業 Product Lineup

"VESTA" is a rubber dewatering agent that improves dispersion in rubber through various surface treatments and masterbatching, while also contributing to the prevention of scattering during roll operations. We offer five different grades in our lineup. Please feel free to contact us if you have any inquiries. 【Features】 ■ Suitable activity level for rubber ■ Coarse particle cut ■ Good dispersion ■ Product grades tailored to needs ■ Low impurities (heavy metals, SiO2, etc.)

We would like to introduce "fine particle calcium hydroxide" that we handle. It is a calcium hydroxide, which has antibacterial effects due to its alkalinity and gas adsorption effects for hydrogen sulfide, hydrochloric acid, and other gases. As a result of evaluating a product with 10% added to LDPE sheets, we confirmed an antibacterial effect with a reduction rate of over 99.9% against E. coli. It is also available as a masterbatch. 【Features】 ■ Antibacterial effect due to alkalinity (slightly soluble in water: pH 12.4) ■ Substance used as a food additive ■ Gas adsorption effects for hydrogen sulfide, hydrochloric acid, and others *For more details, please download the PDF or feel free to contact us.

"Slalric" is a high-concentration calcium hydroxide for slurry that is surprisingly smooth despite its high concentration. It features excellent dispersion when dissolved in water and has high dispersibility that makes it resistant to settling over time. It maintains low viscosity even at a high concentration of 50% w/w. Since the main component is slaked lime, there is no need to handle hazardous materials or toxic substances. It is provided in powder form, allowing for concentration adjustments tailored to the equipment and applications at the usage site. 【Features】 ■ High dispersibility: Resistant to settling over time ■ Low viscosity: Maintains low viscosity even at a high concentration of 50% w/w ■ Flexible concentration adjustment: Provided in powder form, allowing for concentration adjustments based on equipment and applications ■ Safe and easy management: No need to handle hazardous materials or toxic substances *For more details, please download the PDF or feel free to contact us.

"QC2-S" is a highly hygroscopic calcium oxide with small particles and rapid reaction properties. Compared to our conventional products, it has a D50 of 3.2μm, making it a fine particle that supports a wide range of applications, including water absorption and heat generation functions. We also handle calcium oxide that meets food additive standards and pharmaceutical use. The content is 20kg, and the packaging consists of an inner bag made of aluminum and an outer box made of cardboard. 【Features】 ■ Small particles with rapid reaction ■ D50: 3.2μm, Dmax: less than 23.5μm ■ Supports water absorption and heat generation functions *For more details, please download the PDF or feel free to contact us.

"Shimonko Light" is a white powder for deodorants that has a unique layered structure. It physically captures bad odors in the "interlayers" where crystals overlap and traps them inside. The ions in the interlayers and surface layer can bind with odor components both physically and chemically, making it possible to suppress the re-release of bad odors. It exhibits a high deodorizing effect against hydrogen sulfide, ammonia, and others, significantly reducing the "re-release" of absorbed odors compared to activated carbon. [Features] ■ Physically captures and traps bad odors inside due to its unique layered structure ■ Adsorbs odor components from both physical and chemical perspectives ■ Capable of controlling particle shapes such as hexagonal prisms and nanoparticles ■ Exhibits a high deodorizing effect against hydrogen sulfide, ammonia, and others ■ Significantly suppresses the "re-release" of absorbed odors compared to activated carbon *For more details, please download the PDF or feel free to contact us.

"META-Z L40" is a composite active zinc oxide that uniformly combines active zinc oxide with calcium carbonate. Due to its small primary particle size and high specific surface area, the contact efficiency with foaming agents is significantly improved. It enables foaming promotion at lower temperatures, reducing the foaming temperature of PVC by 30°C. Compared to general zinc oxide, it can reduce zinc content by 60%, and due to its high activity, it exhibits equivalent performance with a smaller amount of addition, thus reducing the overall raw material costs of the formulation. [Features] ■ Promotes foaming at low temperatures ■ Excellent dispersibility ■ Cost reduction *For more details, please download the PDF or feel free to contact us.

"META-Z 102" is a high-purity active zinc oxide synthesized by a wet method. Compared to regular zinc oxide, it has a smaller primary particle size and a higher specific surface area, resulting in high reactivity. The reaction efficiency with acidic substances such as stearic acid and vulcanization accelerators is significantly improved. Due to its high reactivity, it can form a dense and uniform crosslinking within rubber, enhancing the tensile strength of the rubber. It also creates a dense crosslinking network, improving compression set (C-set). 【Features】 ■ Improved reaction efficiency ■ Increased crosslink density ■ Improved compression set *For more details, please download the PDF or feel free to contact us.

The "META-Z L Series" is a composite active zinc oxide that uses calcium carbonate as a core (base) and is densely coated with zinc oxide on its surface. Due to its small primary particle size and high specific surface area, it exhibits equal or superior rubber properties even when blended with the same amount of general zinc oxide (equivalent substitution). By replacing the high-density zinc oxide with calcium carbonate, it contributes to the overall lightweight of the product. Additionally, calcium carbonate serves as a base, suppressing "agglomeration" in the rubber and improving the processability of the rubber. 【Features】 ■ Low specific gravity and lightweight product ■ Excellent dispersibility ■ Cost reduction *For more details, please download the PDF or feel free to contact us.
