We are producing silicone profiles by the extrusion of material
through a die (template) that defines their required shape. The extruded
profile is then stabilized by a high-temperature thermal shock. The
final heat treatment is made by means of continuous vulcanization in
horizontal and tunnels and in a finishing vulcanizing oven. Our
manufacturing program involves silicone tubes, various shape profiles,
window and door weather-stripping, facade strips and microporous silicon
We can make them in various colour versions. Owing to the properties
of materials used, the application of silicone profiles is particularly
suitable in equipment for which a healthy operation is essential very
good insulation characteristics, resistance against ozone ageing or
is intended for demanding thermal conditions, such as drying ovens, furnaces, engines, electrical household appliances etc.
Production of profiles as per the customer's drawings is a matter of
course. We are capable of producing extruded profiles of any shape,
maximum sectional area being 1 250 mm2.
We also have at our disposal the technology for continuous cutting of profiles and their subsequent jointing to a desired size.
For circular seals, we can obtain outer diameter up to 60 mm. The
dimensions of sectional seals above 60 mm must be consulted with our
The window weather-stripping SILLEN of various shape versions is
intended to seal windows and doors with different installation
technologies. Compared with similar seals from other materials, silicone
rubber seals have a longer service life, feature better resistance to
solar radiation and a very good shape memory.
