Medical & Biotechnology Applications Ductile, High-Performance Thermoplastic 45678 ARLON 1000 ® ARLON exhibits excellent creep resistance. In two tests (1450 psi tension at 302°F for one week, and 725 psi tension at 356°F for one week) creep was less than 1.75%. (Polyetheretherketone) Ductile, High Performance Thermoplastic ARLON 1000 is a tough, high-temperature, semi-crystalline thermoplastic offering a unique combination of mechanical, thermal, chemical and electrical properties. A comparison between ARLON 1000 and competitive materials appears on page 4.

As a semi-crystalline thermoplastic, ARLON 1000 has a different coefficient of expansion above and below its glass-transition temperature. The values are 2.6 x 10¯5 in/in/°F below 302°F and 6.0 x 10¯5 in/in/°F above 302°F. As with other physical properties, these values can be significantly improved with the addition of reinforcing agents (Figure 3).

Beyond this, ARLON 1000 will continue to deform, but will not break until it has been stretched beyond 35% (Table 1). ARLON offers high shear strength and good resistance to creep. At room temperature, it has a shear strength greater than Nylon 6, and at 500°F exceeds the shear strength of PTFE at room temperature (Figures 1 and 2). ARLON 1000 has excellent fatigue properties, making it an ideal candidate for applications requiring a material that performs well under repeated high stress loads. Not only will ARLON sustain high loading, but because of its crystalline nature, will withstand loads below the critical level of 11,000 psi indefinitely. Amorphous materials, on the other hand, will not exhibit this ability, and show a decline in the level of stress they can handle with an increase in the number of times stressed (Refer to Figure 4).

A Taber abrader was used with a 1000g loading on the abrader arms, with a CS 17 wheel. Results are shown in Table 2. APPLICATIONS ARLON 1000 shows potential in a broad range of applications. TABLE 2 TABER ABRADER RESULTS ARLON is also becoming the number one choice for design engineers when working on surgical instruments. It exhibits excellent fatigue and impact resistance and will not degrade following steam autoclave cycles (see Table 3).

ARLON is recommended for most environments other than strong oxidizers; it exhibits compatibility with acids, bases, aliphatic and aromatic hydrocarbons. Unlike many competitive thermoplastics, ARLON will not hydrolyze and is recommended for use in steam or other high-temperature aqueous environments (Table 3). ARLON 1000 generates no extractables, therefore it is ideal for use in food, pharmaceutical and other industries where microcontamination is a problem. ARLON is frequently specified for liquid chromatography, components such as guard columns, fittings and pump heads. We are also seeing components being evaluated for use in drug discovery equipment, for example microfluidic substrates.

Some limitations exist in diameters and lengths of stock shapes. ELECTRICAL ARLON has excellent dielectric strength, and shows good insulating properties at elevated temperatures. On combustion, ARLON produces low smoke and non-toxic emissions (Table 4). RADIATION RESISTANCE Radiation resistance is a common weakness of PTFE and other thermoplastics; it’s one of ARLON’s strengths. ARLON offers excellent resistance to embrittlement when exposed to gamma radiation, and has outperformed polystyrene, a common radiation resistance material. In addition, this resistance is maintained in both acid and alkali media (Table 5).

PROCESS AND DESIGN While the ultimate performance of any thermoplastic component is limited by the inherent properties of the basic polymer, crystalline materials, such as ARLON, are extremely processing-sensitive. Greene, Tweed exercises tight control over preconditioning, molding and post-molding operations which can affect the level and type of crystallinity of the resulting material. In addition, Greene, Tweed custom designs take full advantage of ARLON’s strengths while minimizing trade-offs. Typical Engineered Grades include: ARLON 1160 – glass reinforced – higher mechanical strength at elevated temperatures ARLON 1260 – carbon fiber reinforced – ultimate mechanical strength at elevated temperatures ARLON 1555 – carbon fiber/lubricated – higher mechanical strength at elevated temperatures, lubricated for lower friction and improved wear resistance ARLON 1330 – lubricated – lower friction, improved wear resistance Greene, Tweed uses only virgin raw material. For information on Engineered Grades, contact Greene, Tweed. ENGINEERED GRADES Greene, Tweed materials specialists continue to develop special grades of ARLON to meet specific requirements. Reinforced grades are available to assure better wear and high strength at elevated temperatures and to improve dimensional stability. Lubricant is also added to certain grades to minimize friction and improve wear resistance. 45678 Corporate Headquarters 2075 Detwiler Road, P.O.Box 305 Kulpsville, PA 19443 USA Tel: (215) 256-9521 Fax: (215) 256-0189 SPECIALTY GRADES AVAILABLE Property Data are typical averages and, therefore, should be used only as a general guide and not for specification purposes.
