Diaphragms and sealings are complex in structure and have to meet the most difficult applications. They not only have to be resistant to aggressive chemicals, oils and fats, but also have to have very good dynamical and mechanical properties. Good product longevity by a constant usage should be guaranteed. So, PTO offers polyester, polyamide and aramid fabrics (Kevlar or Nomex) coated on one or both sides either cured or uncured. For the production of elastomer coated diaphragm cloths many different kinds of rubber such as NBR, CR, CS, CSM or EPDM as well as high performance materials like HNBR, XNBR, ECO, FKM or silicone rubber are used. You can find diaphragms and sealings made of elastomer coated fabrics produced by PTO not only in fuel injection pumps and gasoline tanks of well-known car manufacturer, but also in the measurement and control technology that works with hydraulic liquids of great plants or chemical companies.
