ElringKlinger Kunststofftechnik offers semi-finished products as films/sheets, plates, rings, rods and tubes. The complete product offering is available in four different material versions:
- Virgin PTFE
- Virgin modified PTFE
- Compounds
- Porous PTFE
Compounds-semi-finished products
There is a differentiation made between compounds with anorganic fillers – such as glass fibers, glass pellets, carbon, carbon fibers, bronze, molybdenum disulfide, graphite – and compounds with organic fillers. These include polyimide (PI) polyphenylenesulfide (PPS), polyphenylenesulfidedioxide (PPSO2), polyetheretherketone (PEEK) polyamideimide (PAI) or aromatic polyesters (Econol®, SumikaSuper®).
On request, compounds tailored to virtually any requirement can be produced. Thanks to our in-house compounding we offer app. 500 different compounds. Unless stated otherwise or specified by the customer, semi-finished products are produced on the basis of non-free-flowing compounds. This assures full exploitation of the quality that can possibly be achieved by the basic compound.
Porous PTFE
In case of porous PTFE, density, porosity, air flow value or water column resistance can be varied across a wide range and adapted to specific customer requirements.
Approvals and Regulations
For critical applications, spezial approvals are often required. Thanks to the preferential use of highgrade raw materials – both in terms of the PTFE matrix and the fillers – ElringKlinger Kunststofftechnik supports applications by providing specific certificates, such as for uses involving contact with foodstuffs or the presence of oxygen. In addition, compliance – to the extent applicable – is confirmed for EU Directives, such as 2002/95/EG
(RoHS) and 2002/96/EG (WEEE) as well as many other requirements regulated by KTW, USP Class VI, 3-A Sanitary, NSF, VDA, WRAS or GADSL. |
