Life Science areas such as pharmaceutical, medical packaging and the food and beverage industries require the highest standards of safety, temperature and chemical resistance in production.

To achieve this they need high performance seals that can ensure efficiency and cleanliness. PTFE has been the material of choice. However, PTFE can creep and cold flow, which can lead to a loss of sealing functionality. Kalrez® perfluoroelastomer parts offer the best in class FDA-compliant seals that have elastomeric properties and sealing capabilities.

Kalrez® Perfluoroelastomer (FFKM) parts provide the highest levels of chemical resistance, outstanding thermal & steam resistance and low contamination from extractables for demanding applications in the life sciences sector where FDA compliance is required.

Kalrez® parts deliver optimal sealing solutions through longer seal life versus lower performing elastomers, cleanliness, and high levels of resistance to chemicals and high temperatures. They are resistant to 1800 chemicals and solvents and retain high levels of elasticity and recovery, even after long-term exposure to elevated temperatures. All this results in longer, more effective performance and increased safety and efficiency in production.

Kalrez® Parts include: O-Rings, Sanitary Seals and Custom Parts

Kalrez LS390 Data Sheet

The pharmaceutical and medical packaging industry requires the highest level of safety, cleanliness and efficiency in the production process. Kalrez® parts long seal life improve productivity and process optimization create a safer environment for medical packaging, disposable device handling and as well as creating a safer environment in the day to day running of a pharmaceutical manufacturing facility.

Pharmaceutical manufacturing can often involve the use of aggressive chemicals and high temperatures in the process and because of this Kalrez® parts, with their high temperature and chemical resistance, and long seal life, are the perfect fit for the industry.

Kalrez® is the only elastomer that combines the excellent chemical resistance, including steam cycling, with the cleanliness standards required for pharmaceutical production.

Applications in Pharmaceutical Production Include:

  • Safety Valves
  • Butterfly Valves
  • Mechanical Seals
  • Granulators
  • Sanitary Seals

Applications in Medical Packaging Include:

  • Aerosol rings
  • Microvalves
  • Needle covers
  • Serum stoppers
  • Plungers
  • Infusion hangers

 

 

Kalrez® for Food and Beverage

Kalrez® LS390 for Food & Beverage Applications

The food and beverage industry, as a producer of products for consumer consumption, must meet the highest standards of safety and cleanliness.

Due to the nature of the production process, highly reliable and efficient sealing solutions that are resistant to chemicals and temperatures are needed. Kalrez® parts, which are the most chemically resistant elastomers are the ideal solution. They offer longer lasting, resistant and secure seals which also minimize fluid absorption so taste and smells are not carried over between batches of different products.

Applications in Food & Beverage Include:

Modern Factory Production Line
  • Homogenizing equipment
  • Stirrers
  • Sterilization processes
  • Seals for filling equipment
  • O-rings and sanitary gaskets
  • Bottling and filling equipment
