Moulding compounds

The natural silicone moulding compounds, conventionally two-component, are available in two curing systems – adhesion and condensation. Adhesive curing compounds are characterised by very low shrinkage (<0.1%) and easier handling, but due to the platinum catalyst they are more expensive and more sensitive to contamination. Condensation compounds, unlike adhesion ones, are less sensitive to contamination but have higher shrinkage on cure (approx. 1.5-2%) and are more difficult to handle. The available products have excellent mechanical properties, including high flexibility, which allows very complex parts with so-called “negative angles” to be deformed. They are used for moulding various materials from very hard ones such as concrete and the so called “decorative stone”, to very soft ones like chocolate confectionery decorations. Moulds made of silicone masses are not only mechanically and chemically very resistant, but also work well in high temperatures. Our offer also includes products that enable making moulds for casting metals with low melting temperature.
