In order to reproduce objects – for example, sculptures, models, surface textures or body parts – a mould must be made from the so-called “master pattern”. Elastic materials are the most suitable for making these moulds. We have assembled a list of them under the heading “Moulding materials” which can be found under the category “Modelling, Moulding, Casting”. They are:
• RTV 2 mould silicone rubber
• elastic polyurethane resin
• Latex milk
The following tables can provide you with an overview of the advantages and disadvantages of the various moulding materials.

All the information refers primarily to the materials on offer at Modulor.
1) depending on the type of crosslink
2) Some hardeners require a hazardous label
3) at room temperature (annealing possible if applicable)
4) As long as pouring takes place within 20 minutes of making the mould
The listed materials can of course be used for other purposes – for example, silicone is used to make temperature resistant seals, elastic polyurethane to make foams and latex to make examination gloves.
Then again, hard, elastic materials like plaster are often used to make casts of objects. As a rule, very intricate moulds must be made for this work (see also the entry “Undercuts” in the “Small Lexicon” in the chapter “Silicone”).
