Thermo Materials' Thermo-Sil® Castables are individually formulated for customer specific refractory applications. All castable products consist of the highest quality fused silica and cements and are designed for ease of use with 30 to 40 minute "working" times. Thermo-Sil Castables are noted for their superior performance in areas requiring resistance to thermal shock, precision and durability. Thermo-Sil Castables are packaged in 50 lb. (22.7 kg) plastic-lined paper bags, 40 per pallet.

Thermo-Sil® Castable TG

Thermo-Sil Castable TG (Technical Grade) is a low cost, industrial grade castable for general industrial uses requiring extreme thermal shock resistance and general toughness. Castable TG is formulated using high quality fused silica grog and hydraulic setting, high purity calcium aluminate cement. Castable TG is also available in a low cement version resulting in higher strengths.

Thermo-Sil® Castable 120

Thermo-Sil Castable 120 (Precision Casting) is a low cost, fused silica based castable designed for use as a durable insulating material in induction heating units. This castable is a thermal shock-resistant nonreceptor that directs all the energy to the product being heated. Thermol-Sil Castable 120 exhibits very low shrinkage and is sometimes employed as a high temperature tooling material.

Thermo-Sil® Castable ICL

Thermo-Sil Castable ICL (Induction Coil Lining) is a modified version of Castable 120 that employs a small amount of abrasion resistant ceramic. Castable ICL is used in areas where abrasion in an induction heating system may be the primary mode of failure.

Thermo-Sil® Castable 220

Thermo-Sil Castable 220 (Tooling Castable) is primarily employed as a precision high temperature tooling material. Specific applications include the high temperature forming of glass and titanium products. The castable is comprised of precisely sized, high purity fused silica and silicon carbide ceramic materials and employs a calcium aluminate binder. This castable is designed to produce highly accurate tools ranging in size from less than ½ cubic foot to more than 70 cubic feet. Cast shrinkage is negligible and the tools remain true and accurate through 1,000° C.
