Shaft-Seals made of PTFE (Teflon®) are characterised by higher temperature resistance, better chemical resistance and good dry running properties. ttv offers three possible designs: from the mold – under strain – compressed. The design „from the mold" is often selected by our customers due to the technical and economic advantages. „Strained" designs however, are available in different designs, even with lower quantities. Due to the excellent sterilisation properties of PTFE, shaft seals in „compressed" design are especially suitable for the food and pharmaceutical industries. Similar to the strained designs the tooling costs are very low and a variety of designs is selectable.
