Poolkemie POLIMOLD HR 25

Poolkemie POLIMOLD HR 25 is a two component room temperature vulcanising fluid rubber which cures after addition and mixing with the appropriate catalyst: it produces an elastic and tenacious mass, free from bubbles and imperfections; it has a good stability to hydrolysis, very good mechanical resistance, is easy to demould and has a percent shrinkage approx. = 0. Poly-urethane rubbers of POLIMOLD HR series, once cured, have a light superficial greasiness caused by proper release agents in order to favor demoulding operations.

Application

Low and medium hardness types (HR 25 – 30) are suitable for reproduction of complex patterns with undercuts; high hardness types are specially suited for reproduction of large-sized patterns. Molds made of POLIMOLD HR are suitable for mass-production plaster and cement handworks, for artistic foundry (loosewax method), in wax industry (decorative candles).
