Polymer melt: custom filter elements made to measure
HYDAC supplies candle filters, filter discs and spin pack filters
The polymerisation of plastic produces impurities that need to be filtered. At our production facility in Germany, we develop and manufacture filter element technology at the highest level. Discover how our polymer filter elements can improve your process efficiency. We design elements that are tailored to your needs – find out more about our expertise here.

High-performance filters for polymer melt and solvent filtration for critical processesDesign & production in Germany
In plastics processing plants, for example in granule, fibre, cable or film production, small particles and gels can lead to major problems. Thanks to our decades of experience in the fields of stainless steel element technology and polymer filtration, we have extensive expertise ranging from design (material selection, layer structure, computational fluid dynamics) and production (pleating technology, cleaning processes, welding technology, quality assurance) to filter analysis and in-house testing.

Optimise your polymer melt filtration
Experts since 1992 – at our production facility in Germany, we develop and produce highly efficient filter elements that are tailored to your needs. In doing so, we rely on resistant mechanical connections (crimping) and sustainable materials (cleanable filter materials). Thanks to our decades of experience in the field of polymer element technology, we have extensive expertise, especially in the welding technology sector, which opens up possibilities for function integration (e.g. seal-less designs). This enables us to provide you with a broad product range – whether it's candle filters, filter discs (screen discs) or spin pack filters.
The secret to success: Chemicron®High contamination retention capacity and porosity up to 90 %
Chemicron®metal fibre fleece consists of a large number of very thin and homogeneously distributed stainless steel fibres (316L, special materials on request), which are firmly bonded together via a sintering process.
The main advantages of the highly porous filter material over other materials, such as wire mesh and sintered metals, are its high contamination retention capacity and porosity of up to 90 %.
Applications in the polymerisation of plastic
Our high-performance filter materials are used in polymer melt filtration and solution filtration, e.g:
- XLPE compounds for the production of high-voltage cables
- Polysulfone in medical technology
- Polypropylene for packaging films
- Reactive resins (e.g. epoxy resins, polyols and polyisocyanates)
