For decades, ELASTOSIL® M silicone rubber has been the ideal solution for the production of molds that are highly elastic and have excellent release properties and optimum durability. These invaluable processing properties make ELASTOSIL® M indispensable, to both industrial and artisan mold makers.

Condensation- and addition-curing ELASTOSIL® M silicone rubber products win over professionals in the field of creative mold making, because they faithfully reproduce the original, are highly resistant to various reproduction materials and are easy to process.

Advantages:

  • Exceptional detail accuracy
  • Suitable for high volume series
  • Easy to process without expensive equipment

Applications:

  • Replication of art objects
  • Molds for jewelry production
  • Molding processes in foundries

Industrial applications require a high degree of product reliability, long-term stability and the ability to process the material used efficiently – a tailor-made requirement profile for silicone rubber. ELASTOSIL® RTV-2 silicone-rubber mold-making compounds are just the thing for this and much more.

Advantages:

  • Exceptional detail accuracy
  • Suitable for mass production
  • Easy to process without expensive equipment

Applications:

  • Molds that reproduce shape and surface structures in industrial processes

A neutral effect on taste, long-term stability, precise reproduction of the shape of a wide variety of food products, and compliance with legal regulations are at the heart of the requirements placed on molds used in food production.

Advantages:

  • Neutral effect on taste
  • Highly precise reproduction of details
  • Long-term stability

Applications:

  • Molds for making and decorating cakes, tarts, chocolates, desserts, etc.
