Birmingham Rubber & Plastics carries the most complete and versatile line of liquid mold rubbers, liquid casting plastics/resins/foams and other specialty molding and casting materials from Polytek Development Corp. These mold materials include two-part, high-performance RTV polyurethane, silicone as well as one-part latex and other specialty systems. These liquid rubbers and plastics are used in countless applications where the flexibility and ease-of-use of rubber molds are needed to create exact, highly detailed reproductions of any original model in concrete, plaster, resin, foam, wax and more. Individual artists, sculptors, hobbyists, model makers and industrial users rely on Polytek products and technical support to accurately mold and reproduce parts quickly, consistently, and cost-effectively.

TinSil 80-15, 80-30

Silicon Rubbers

These two-part, room temperature curing systems offer the greatest flexibility, tear strength and chemical resistance and eliminate the need for release agents when resin casting. Well-suited for almost any casting medium (plaster, wax, concrete, resin and foam) these mold materials are ideal for repeated casting in liquid resins/plastics/foams. More expensive than polyurethane rubbers, but well worth the expense when casting higher volume resin casting is required.
