        Rilsan? Clear MED Transparent Semi-Rigid Polyamides:

        • Breathing Masks
        • Fittings

        Pebax? MED Range

        Medical grade Pebax? polymers are plasticizer-free thermoplastic elastomers with a wide range of physical and mechanical properties achieved by varying the monomeric block types and ratios.


        Grades within the product range extend from soft, flexible and elastomeric to those with mechanical properties approaching semi-rigid polyamides. 
        The remarkable processing ease of medical grade Pebax? elastomers make them an excellent choice for extrusion of medical grade tubing or film applications. They are often compounded by our customers for additional lubricity or radiopaque properties.

         

        Their lightness and tremendous durability makes them very good candidates for wearable applications such as straps and fasteners.

         

        Typical properties include:


        ? USP Class VI* certification
        ? Sterilization resistance
        ? Bondable by adhesives or RF welding
        ? Easily blended with other polymers and compounded with additives
        ? High torque transference, maneuverability and kink resistance
        ? Excellent impact resistance and low rigidification at low temperature
        ? Consistent durometer and flexibility at room and body temperatures
        ? Good resistance to many harsh chemicals

        ? Lightweight and high maneuverability

        ? Pebax? MV 1074 SA 01 MED: hydrophilic grade with inherent antistatic properties (surface resistivity 3 x 109 Ω / sq.)

         

        Breathable Pebax? MV 1074 SA 01 MED is often considered for breathable wound care, surgical garments (disposable) and bedding materials. (Datasheet US/SI)

         

        * Pebax? MED grades have undergone testing in accodance with certain portions of the USP Class VI and/or ISO 10993 standards. Contact us for details.

        Rilsan? MED and Rilsamid? MED Semi-Rigid Polyamides

        Medical grades Rilsan? MED polyamide 11 and Rilsamid? MED polyamide 12 are used in applications that require the strength and performance characteristics of a true thermoplastic, yet still offer sufficient flexibility and elongation approaching that of some elastomers. Rilsan? and Rilsamid? MED polymers are easy to process by most traditional methods, including extrusion, extrusion blow molding, injection molding and rotomolding. Exceptional properties of these polyamide products include:

         

        ? High strength and mechanical properties
        ? Excellent resistance to chemicals (particularly hydrocarbons)
        ? Ease of processing

        ? Wide range of application temperatures [ -40°—130°C (-40°F—266°F) ]
        ? High dimensional stability and low density
        ? Very low gas permeation

        When High Transparency is Required

        Rilsan? Clear MED grades offer an outstanding combination of transparency, light weight, chemical resistance and flexibility used in applications like BPA free and BPS free breathing masks, tubing, and storage containers.

         

        Rilsan? Clear G170 MED polyamide offers an excellent combination of transparency, light weight, and flexibility of transparent polymers commonly used in medical applications. It is more transparent than glass and more flexible than polycarbonate.

         

        Transparent: Light transmittance of 91% - exceeding that of glass and polycarbonate

         

        Light Weight: Specific gravity of 1.05, Rilsan? Clear G170 MED is about 15% lighter than traditional transparent medical plastics such as acrylics, polycarbonates or PSU.

         

        Flexible: Flexural modulus of 1,980 MPa (287,000 psi), representing an approximate18% improvement in flexibility compared to polycarbonate.

         

        Durable: High temperature resistance (Tg = 168°C), good surface and wear resistance, good chemical resistance.

         

        Rilsan? Clear G170 MED is BPA and plasticizer free, and is sterilizable (contact us for information on Steam, ETO and gamma sterilizations).
