• Ceramics

The use of inorganic fillers in resins and sealants such as rubber and plastic is increasing, while problems caused by moisture content are also on the rise. In general, the particle surfaces of inorganic fillers are hydrophilic, which can lead to unexpected issues during use as they adsorb moisture from the air while being stored. The "WAC Series" absorbs moisture in environments that repel it, demonstrating the same effectiveness as when the material is dry, serving as an additive anti-foaming agent. Due to surface treatment, dispersion and compatibility with resins are improved, and enhanced fluidity of sealants can be expected. 【Features】 ■ Absorbs moisture in environments that repel it ■ Demonstrates the same effectiveness as when the material is dry as an additive anti-foaming agent ■ Improved dispersion and compatibility with resins due to surface treatment ■ Enhanced fluidity of sealants can be expected *For more details, please refer to the PDF document or feel free to contact us.

The "AHT Series" is a composite filler made of talc and calcium carbonate. When only talc is added to olefin-based resins to enhance rigidity, it has the drawback of reducing impact resistance. This issue is resolved. The filler is dispersed at the primary particle size, allowing for the expected improvement of both the rigidity of talc and the impact resistance of calcium carbonate, which have opposing mechanical properties. Furthermore, because it is surface-modified with organic agents, it has excellent dispersibility, leading to improved workability. 【Features】 ■ Filler is dispersed at the primary particle size ■ Expected improvement of both opposing mechanical properties of talc and calcium carbonate ■ Excellent dispersibility and improved workability *For more details, please refer to the PDF document or feel free to contact us.
