NaturForm™ 60 Molding Latex Rubber


Polytek® NaturForm™ 60 Molding Latex Rubber is a 58-62% solids natural latex with excellent tear strength and elongation properties. To make a mold, multiple layers of this latex are brushed (spray application is not recommended) onto an original model to form a tough rubber blanket mold (each layer must dry before the next layer is applied). These thin molds are typically backed with a supportive mold shell.

Molds made with natural latex are often used for casting plaster, concrete (e.g., veneer stone manufacturing and statuary) and limited casting with some resins.

For a latex with internal mold release, select NaturForm™ 60-R Molding Latex Rubber. For a high solids (70-74%) option, select NaturForm™ 74 Molding Latex Rubber
