Kalrez LS222 seals are designed specifically for Life Science markets
The LS222 perfluoroelastomer product recently launched in the DuPont Kalrez range of sealing products is available in the UK from Dichtomatik, an official licensee supplier of DuPont products.
This product range has been designed specifically for operation in the Life Science markets including pharmaceutical and medical packaging together with the food and beverage industries.
The qualities provided include operation at elevated temperature levels, combined with chemical resistance to ensure that these sealing products can be used in a range of devices.
This can include aerosol rings, infusion hangers, microvalves, needle covers, plungers and serum stoppers.
Typical applications that include pharmaceuticals production include safety and butterfly valves, granulators and both mechanical and sanitary seals.
Applications associated with food and beverage production include stirrers, together with homogenising, filling and bottling equipment, as well as sterilisation and O-ring seals plus sanitary gaskets and custom parts.
This LS222 (FFKM) range offers FDA-compliant seals, with both appropriate elastomeric properties and high endurance and sealing level capabilities.
The FFKM products feature high thermal and steam tolerance up to 327°C, as well as extensive chemical resistance qualities to more than 1,800 different chemicals.
The LS222 products represent a major expansion to the Kalrez range to meet demands from equipment OEMS who require high volumes of specific high quality sealing components (i.e., applications requiring FDA and/or USP VI certification).
Typically such applications cover more than 10,000 parts per order, with packages of 500 pieces per bag. These requirements are typically for O-ring and custom parts featuring outer diameters up to 50.8mm. Alternative sizes and special shapes can also be manufactured to order.
