Silicones and Perfluoroelastomers...
Silicones (VMQ), Fluorosilicones (FVMQ), Phenylsilicones (PVMQ) and Perfluoroelastomers (FFKM) are mixed in a separate building, in positive pressure clean room environments.
Silicone facilities include a Z-blade mixer (for mixing special additives, eg fine particulate metals) , and a custom designed mill, with variable speed and friction ratio. This enables it to be operated without using the traditional scraper blade- a potential source of contamination. The specialist bearing system prevents oil loss, and interchangeable nylon stock guides are fitted for ease of cleaning.
Colour matching is a speciality, and the colour of every batch is verified by spectrometer before dispatch.
All silicone compounds are heat sealed into polythene bags before packing for transport.
FFKM is produced in a separate clean room, and the mill is adapted to mix batch sizes from 200g to 1kg. All compounds are vacuum packed into foil bags.
