P-50
Product Information
General Information
P-50 is a two component addition cure silicone rubber mold making material. It has a high durometer, high modulus, superb physical properties, minimal shrinkage and extreme chemical resistance making it an excellent choice for prototyping, casting urethane foam and other plastics. P-50 also serves as an excellent choice for use in trapped rubber molding and pressure intensifier applications when working with composites or Heat transfer.
