Expert Application Engineering

Pure and Stable Pharmaceutical Sealing Solutions


Our Chemraz® SD517 and Chemraz® SD625 PTFE-like sealing materials perform against the most challenging pharma manufacturing and processing conditions:

  • Resistance to Q3C Class 3 solvents
  • Minimale extrahierbare Stoffe in wässrigen bis unpolaren Systemen
  • Herstellung und Verpackung im Reinraum (nur SD517)
  • Sehr hohe thermische Stabilität (bis zu 260 °C)
  • Long service lifetime compared to silicone, EPDM, or Viton™
  • Langzeit-Stabilität bei gewöhnlicher Sterilisation, Pyrogeninaktivierung und Prionen zerstörenden Bedingungen (nur SD625)

Carbon Fiber PEEK


Cut out risk of strain, injury, and life-threatening errors caused by heavy stainless steel alloys. And not by relying on weak plastic replacements.

Our Orthtek® WF 50% carbon fiber PEEK composite outperforms metal and other plastics:

  • Sehr leicht (1,54 g pro cm3), wodurch Belastungen und die Verletzungsgefahr reduziert werden
  • Strahlendurchlässig, wodurch die Klarheit von Röntgenbildern verbessert und die Exposition der Patienten reduziert werden
  • Vergleichbare Stärke zu Metall
  • Structural material for insertion jigs, fixator rings, and other external medical devices
  • Available in small custom batches (10s of units) or larger mass quantities (100,000s of units)

Long-Term Performance


Dichtungen sind ein Schwachpunkt in vielen HPLC- und SEC-Instrumenten und Sensoren in Prozessen. Find the reliability you need in your analytical instruments with our sealing solutions. 

Our products perform under extreme chemical, pressure, and temperature conditions. They extend the life cycle of your instruments and help avoid preventative maintenance.

Greene Tweed offers Chemraz® 605 in standard parts, custom designs, or sheets. Its excellent compression rate and extrusion resistance ensure lasting performance.

Industry-Proven Products

Pharmaceutical Sealing Solutions

The most common type of elastomer seal, o-rings provide cost-effective, flexible sealing solutions across a wide range of demanding applications. Greene Tweed offers Chemraz® SD517 and Chemraz® SD625, high-performance PTFE-like sealing materials that offer unparalleled stability and lifetime service to nearly all pharmaceutical manufacturing and processing conditions.

High-Performance, Low-Friction

Greene Tweed’s low-friction, ultra-durable rod and piston seals offer an outstanding combination of easy installation, low leakage, and longer service life for exceptional performance in static and dynamic sealing applications.

They are constructed of superior elastomers and thermoplastics designed to withstand harsh conditions, O-ring roll, and spiral failure in the most challenging conditions.

High-Strength, Lightweight Medical Technology

Greene Tweed offers precision-molded thermoplastic components for a wide range of x-ray applications, medical tools, surgical instruments, and other hospital equipment.

Available in three patented materials (Orthtek®, Xycomp® DLF®, and Arlon® 1260), our custom designed medical components provide superior strength to weight ratio, chemical resistance, and service life to their metallic counterparts.

Extreme Temperature and Corrosion Resistance

If you’re looking for wafer handling and cleaning components built to function in high-temperature and corrosive environments, Greene Tweed will work with you to find the right material and solution for the job.
