Tulsimer® range of filters from Thermax are exclusively used in Investment Casting process. These are available in the form of free flowing powder or beads with very high thermal stability and very low ash content. Tulsimer® polymers are highly inert and are not affected by acids, alkalies, aliphatic alcohol and aromatic solvents.

Advantages

• Low ash content for fine surface texture.
• High melting point for immiscibility with wax.
• High thermal stability for minimum and uniform expansion and contraction.
• Fine particle size for producing high quality precision parts.

Benefits

These products are mixed with wax during the Investment casting process. When wax is heated to liquid state, these filters give minimum and uniform expansion and contraction due to their amorphous structure and hence give a fine surface texture to the finished product.
