Therma DM220

Therma DM220 is a material specially developed for rubber moulding.

It is suitable for the production of master models, both thick and thin, in order to make both vulcanised rubber moulds and rubber moulds with liquid silicones, RTV. Therma DM220 makes models with extremely smooth surfaces and resistant to temperatures up to 200 °C.
