With over 200 engineers working across three continents, Greene Tweed has the expertise and knowledge to support critical Life Sciences applications. 

Greene Tweed collaborates with our customers to design and develop modern solutions for harsh conditions and extreme environments. 

Our engineering experts combine application knowledge with best-in-class materials like Chemraz®, Orthtek®, and Avalon® and provide the documentation, testing, and expertise to support your application. 

Expert Application Engineering

Proven Pharmaceutical Sealing Solutions 


Chemraz® SD517 and Chemraz® SD625 are PTFE-like sealing materials built to handle the most challenging pharma manufacturing and processing conditions: 

  • Resistance to Q3C Class 3 solvents
  • Minimal extractables in aqueous to nonpolar systems
  • Cleanroom production and packaging (SD517 only)
  • Very high thermal stability (up to 260°C)
  • Long service lifetime compared to silicone, EPDM, or Viton™
  • Long-term stability in common sterilization, pyrogen inactivation, and prion-destroying conditions (SD625 only)

Carbon Fiber PEEK Performance 


Our Orthtek® WF 50% carbon fiber PEEK composite outperforms metal and other plastics while reducing risk of strain, injury, and life-threatening errors: 

  • Lighter than metallic counterparts (1.54 g / cm3) for reduced strain and injury risk
  • Radiolucent to improve x-ray clarity and limit patient exposure
  • Comparable strength to metal
  • 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)

Reliable Performance 


When it comes to HPLC and SEC instruments and in-process sensors, equipment failure is not an option. 

Greene Tweed solutions are built to perform under extreme chemical, pressure, and temperature conditions, extending the lifecycle of your instruments and reducing costly downtime. 

Boasting excellent compression rate and extrusion resistance, Chemraz® 605 is available in in standard parts, custom designs, or sheets.

Industry-Proven Products

Proven Pharmaceutical Sealing Solutions 

The most common type of elastomer seal, O-rings provide affordable, flexible sealing solutions for industry’s most demanding applications. Chemraz® SD517 and Chemraz® SD625 deliver high-performance PTFE-like sealing with 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. 

These high-performance elastomers and thermoplastics are designed to withstand harsh conditions, O-ring roll, and spiral failure in the harsh operating conditions. 

Lighter, Stronger 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), these custom designed medical components deliver superior strength to weight ratio, chemical resistance, and service life to their metallic counterparts. 

Extreme Temperature and Corrosion Resistance

For wafer handling and cleaning components built to function in high-temperature and corrosive environments, our experts work directly with you to develop a solution tailored to your needs.
