Find the perfect polymer for you…
We have dedicated mixing facilities along with an exclusive workforce to compound speciality polymers such as FKM (including Viton™), FFKM and a wide range of different Silicone grades.
These compounds are at the forefront of our business and our technical staff have an extensive range of knowledge on the grades we have available and how to effectively formulate with them to achieve the desired results you require from the compound. Due to the increase in cost of such speciality materials we understand how important it is to meet your requirements first time and working alongside us, we can achieve that together.
Clwyd Compounders supply materials for use in a wide range of industries, information about widely used polymers in a selection of our main markets is given below:
Perfluoroelastomers - FFKM
The ultimate elastomer for applications where only outstanding performance is good enough; suitable for use over a temperature range of -40 to 320°C.
- Seals for cabinets used in the manufacture of semiconductors, where plasma resistance is essential
- Reaction column seals for the chemical industry
- Deep well drilling applications, requiring prolonged performance at temperatures > 250°C and resistance to high pressure steam and amines
- Food industry applications where there is a requirement for high performance whilst undergoing high pressure steam cleaning
Clwyd Compounders have extensive experience of compounding these materials, and will take into account the full range of factors which may affect compound performance under these extreme conditions, so that you can order these very expensive materials with confidence.
All perfluoroelastomers compounds are produced in a dedicated clean room facility, and vacuum packed into foil bags for dispatch to avoid contamination.
Fluoroelastomers - FKM
Clwyd Compounders have been at the forefront of fluoroelastomer compounding for over 20 years. We have a dedicated internal mixer for fluoroelastomer compounds which uses dry PEEK seals to eliminate oil contamination, and extensive use is made of 2-stage mixing to enhance compound consistency.
Fluoroelastomers are often considered to be a single polymer type, but fluoroelastomers can be further subdivided on the basis of their monomer type(s). Different fluoroelastomer subtypes offer different compound properties (dependent on their constituent monomers and cure systems), which can lead to significant differences in compound performance. This large family of elastomers include polymers that are capable of resisting oils, methanol, caustic or corrosive chemicals, steam and extremes of temperatures (as low as -50°C or as high as 320°C). As fluoroelastomer specialists, we can help guide you to the most suitable fluoroelastomer subtype for your needs.
High Performance Silicone Compounds
We can supply silicone (VMQ), fluorosilicone (FVMQ) and phenyl silicone (PVMQ) compounds suitable for applications ranging from medical to aerospace.
We also offer a range of specialised silicone and fluorosilicone compounds which contain specialist materials or additives. This range of compounds offers additional special properties, and includes:
- Conductive Silicone Compounds (loaded with graphite, carbon nanotubes or other specialist composite materials)
- Antimicrobial and antifungal silicone compounds
- Metal-loaded silicone compounds
- Magnetic silicone compounds
