We know sealings – and your needs
In addition to tightness, low coefficients of friction and a long service-life are often required to keep maintenance intervals as long as possible. In many industries, globally valid approvals are also required – whether for the food and beverage industry, the pharmaceutical industry and medical technology, the drinking water industry or in the oil and gas sector. In recent years, Angst+Pfister has invested heavily in the development of high-performance elastomers and currently has a wide range of materials available with many of the approvals required worldwide for the highest industry requirements. There, in the area of sealing technology, materials such as FFKM, FKM, EPDM, HNBR, VMQ but also PTFE play an important role. Other important industries we serve with customized solutions are the area of agriculture, the automotive industry and the general machine industry.
