Silicone

Silicone, cured polydimethylsiloxane (PDMS), is an inorganic polymer. In comparison to organic polymers based on a carbon backbone, silicone is based on silicon and oxygen.

Silicones are duroplastic elastomers, thus after curing they cannot be melt processed. Good non-stick properties, a high degradation temperature and a low glass transition temperature (-120 °C) result in a wide temperature application range (-80 °C up to 180 °C).

Silicone coated fabrics

knife coating process

Silicone coated fabrics are produced mainly via a knife coating process. The uncured high viscous silicone paste is applied on the fabric. A knife bar in a defined distance to the fabric determine the layer thickness of the silicone coating. In a consecutive oven the silicone is cured via a hydrosilylation addition reaction (Pt- catalysed).

The curing temperature is lower compared to PTFE. Therefore, a broad variety of fabrics can be used, such as glass, aramid, polyester, polyamide. Additives in the silicone can change the properties. The temperature stability is improved by Fe 3 O 4 .
