3 Materials (sealing elements) Materials of construction meant for use in sealing and guiding applications are expected to have outstanding mechanical and chemical characteristics. 1. Low permanent deformation (good compression set behaviour) 2. High abrasion resistance and low wear 3. Good temperature stability 4. Compatibility in most of the pressure medium as used in hydralics. 5. Excellent mechanical characteristics. Materials used in manufacture of ACCOFLUOR sealing systems undergo constant and stringent quality checks. This assists in enhancing the function and service life of the seals. ACCOFLUOR seals are regularly produced from one or more of the following materials: Fiber elastomer combinations These materials are used in very demanding application environments. They display good pressure, abrasion and flow resistance and good anti stick slip behaviour. Elastomer blends from natural or synthetic rubber These materials are used in the manufacture of sealing elements that give high elasticity and ease of assembly . Flexible thermoplastics These materials (polyurethane, polyester elastomers) are used in sealing elements, wipers and back-up rings with very high elasticity, abrasion resistance and compressive strength. Rigid thermoplastics Highly resistant materials (polyamide, polyacetal) are used in the manufacture of sliding elements and back-up rings. Fluorine containing thermoplastics with and without reinforcements This group mainly comprises of PTFE and related compounds. Seals, wipers and guides manufactured from these materials primarily relate to applications that require low friction and high resistance and stability. Thermosetting plastics These composites (phenolic, polyester resins and fabrics or polyester fiber) are used in peripheral components of sealing systems such as supporting components and strip material.
