丸釜釜戸陶料 Product Lineup

The crystalline silica filler wet grinding product category includes the SNOWMARK SP series and the Yukijirushi Silica Grade series, both made from high-purity "white silica" produced in India and Sri Lanka, utilizing the grinding technology and manufacturing know-how developed by Marugama to create crystalline crushed quartz. "White silica" is characterized by its low content of alkali metal elements and excellent electrical insulation properties. Other properties include arc resistance, acid resistance, chemical resistance, and wear resistance. Additionally, SNOWMARK SP-3, SP-5, and Yukijirushi Silica Special Grade No. 4 comply with the positive list of the Polyolefin Hygiene Council. ◆ SNOWMARK SP Series 　(SP-3, SP-5, SP-10, SP-20) ◆ Yukijirushi Silica Grade Series 　(Grade 1, Special Grade No. 2, Special Grade No. 4)

• Ceramics

Crystalline silica filler dry ground products include the Snow Brand Silica CVG series, which is made from high-purity "white silica" produced in India and Sri Lanka. It is dry ground, classified to adjust particle size, and then dried to produce crystalline crushed quartz. ◆ Crystalline silica filler dry ground products Snow Brand Silica CVG series (CVG-5, CVG-6, CVG-7, CVG-20)

• Ceramics

The category of wet-ground fused silica fillers includes the M.Quartz MS series, which is produced using high-quality fused silica ingots and powders as raw materials, leveraging the crushing technology and manufacturing know-how developed by Marugama to create crushed fused silica. ◆M.Quartz MS Series (MS-1, MS-2, MS-4, MS-7, MS-12)

• Ceramics

The category of dry ground fused silica filler includes the M.Quartz TF series, which is made from high-quality fused silica ingots and powders that are dry ground and classified to adjust particle size, followed by drying to produce crushed fused silica. ◆M.Quartz TF Series 　(TF-15, TF-22, TF-35, TF-200)

• Ceramics

This is a product group of relatively larger powder particles adjusted to a particle size range of 4mm or less through dry classification of raw materials for fused silica. ◆ Macro Size Series (4-0.84, 3-1, 2-1, 1-0.5, 0.84-0.3, 0.5-0.2, 0.5-0.1, 0.3-0.1, 0.2-0.1, 1-0, 0.5-0, 0.2-0, 0.1-0)

• Ceramics

This is a group of relatively small powder products with adjusted particle sizes achieved through the crushing, classification, and mixing of raw materials for fused silica. ◆Micro Size Series (F-40, F-44, F-90, F-105, F-160, L-44, L-90, L-105, L-149, L-250, LS-44, Y-44, Y-74, 100 Mesh under)

• Ceramics

This is a surface treatment product that adds various properties by adding a coupling agent to silica filler as a raw material. Additionally, since silane-based coupling agents need to be selected based on the type of resin used, all surface-treated products are made to order. Furthermore, the surface treatment series not only combines "inorganic and organic" but also allows for the treatment that disperses the aggregation of fillers.
