Proven performance in key areas
From proprietary FDA compliant and chemical resistant Turcon® compounds to engineered, high wear resistance Zurcon® materials, Trelleborg Sealing Solutions can design products from a range of high-performance engineered plastic compounds optimized for specific applications to provide proven performance in key areas.
Fluorinated Ethylene Propylene
Typical Healthcare & Medical Applications: Labware and tubing where highly corrosive processes are used.
Products Available: Tubing and coatings
Fluorinated Ethylene Propylene (FEP) is a copolymer of hexafluropropylene and tetrafluroethylene and differs from PTFE in that it is melt-processable using injection molding and screw extrusion techniques. Providing low friction, it is inert to most chemicals and is also highly transparent and resistant to sunlight. FEP is slightly more flexible than PTFE but has higher friction and lower tensile strength.
High Modulus Plastic Materials
Typical Healthcare & Medical Applications: Wheelchair hub bearings, actuators, valve seats, reciprocating and oscillating applications
Products Available: Bearings, Flatseal™, Slydring®, Wear Rings, Back-up Rings, Custom Shapes
HiMod® refers to a range of high-modulus plastic materials that Trelleborg Sealing Solutions has developed for applications demanding high wear and chemical resistance performance. The materials also exhibit low friction performance through the use of a unique balance of internal lubricants and wear inhibiting agents. These materials can be machined or injection molded, providing engineers the design freedom to develop the most economical manufacturing method.
The HiMod® Flatseal™ range consists of flat gaskets from the proprietary HiMod® material offering superior performance compared with conventional polytetrafluoroethylene (PTFE) flat gaskets. They are compliant with virtually all relevant standards including FDA. The product is die cut and is available in any standard or customer specified dimension. The HiMod® Flatseal™ products are manufactured in facilities that comply with ISO/TS 16949 and ISO 14001, meaning complete transparency in all degrees of production and a high degree of reliability and security for customers.
Typical Healthcare & Medical Applications: Catheters, fluid dispensing, laboratory use
Products Available: Tubing
Nylons are a family of synthetic polymers known as polyamides. They can be used to make mechanical parts such as gears and screws, and can also be extruded. Nylons are lightweight and resistant to corrosion and abrasion. FDA and USP Class VI grades are available. Medical tubing applications include suction, drainage, feeding tubes, dialysis, peristaltic pumps and other surgical procedures.
Polyether Ether Ketone
Typical Healthcare & Medical Applications: Pistons, pumps, valves, fluid transfer
Products Available: Bearings, springs, tubing, custom shapes
Polyether Ether Ketone (PEEK) is a good choice for applications where fluid compatibility is a concern. It is virtually inert and has good mechanical properties, providing low friction and wear. High strength, toughness and biocompatibility make PEEK ideal for many medical device applications.
Medical Grade Polyvinyl Chloride (PVC) Tubing
Typical Healthcare & Medical Applications: Catheters, peristaltic pumps, fluid transfer, oxygen transfer
Products Available: Tubing
Polyvinyl Chloride (PVC) is available in rigid and flexible forms. PVC can be extruded in a wide range of durometers and colors to meet virtually any need. Medical grade PVC tubing is resistant to many chemicals, solvents, corrosion and has a long life expectancy. It is also resistant to most sterilization methods. It’s extremely smooth surface provides maximum fluid flow characteristics, reducing sediment build up which could lead to bacterial growth.
Typical Healthcare & Medical Applications: Single-use systems, peristaltic pumps, bioreactors, sterile filling and filtration
Products Available: Tubing
Thermoplastic Elastomers (TPE) are a copolymer mixture of a rubber and a plastic and exhibit properties of both materials. TPEs require virtually no compounding, reinforcing agents, stabilizers or curing agents, providing consistent batch to batch properties. When extruded into tubing, the material is translucent, flexible, resists kinking, making it ideally suited for pumping and fluid transfer applications.
Provides High Sealing Efficiency
Typical Healthcare & Medical Applications:Static, reciprocating and rotary applications, applications with low downtime requirements (serum and pharmaceutical production), mixed process streams in multipurpose equipments, CIP & SIP cleaning regimes, low and high temperature applications
Inherently, Polytetrafluoroethylene (PTFE) is compatible with almost all chemicals, making it ideal for use in equipment where seals are likely to be exposed to aggressive media, including CIP and SIP regimes. Specific operating properties are achieved by the addition of fillers and special processing technologies.
Incomparable Material Range
Turcon® compounds have very good slide properties with low-friction and no stick-slip, provide high sealing efficiency and a long service life, meet demanding service conditions and provide high-flexibility for easy installation. Our wide variety of Turcon® formulations ensures that we will have just the right material to meet the specific needs of our customers’ healthcare and medical applications.
Trelleborg Sealing Solutions is the world’s largest manufacturer of seals in this type of material, and no other supplier offers such a wide variety of grades.
Engineered Plastic Materials
Typical Healthcare & Medical Applications: Reciprocating and oscillating applications
Products Available: O-Rings, Wipers, Variseals, Glyd Rings, and Pneumatic Seals.
Zurcon® is the brand name for the Trelleborg Sealing Solutions range of engineered plastic-based materials. Its low friction characteristics make it ideal for reciprocating, very slow rotating and oscillating situations where high wear resistance is required.
