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%.

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.

ARLON’s crystalline melting point of 633°F offers potential for
applications at temperatures above 500°F.
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).

MECHANICAL/THERMAL
ARLON 1000 has a tensile strength at yield of 15,260 psi and an
elongation at yield of 6%. 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).

ABRASION
Tests were carried out to determine the relative abrasion
resistance of injection molded ARLON 1000, UHMW polyethylene,
nylon, acetal and PTFE. 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).

CHEMICAL
Since ARLON 1000 is a crystalline polymer, its resistance to chemical
attack is excellent (its only known solvent is concentrated sulfuric
acid). 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.

AVAILABILITY
ARLON 1000 is available in rod, tube and disc as well as in injection
molded and machined components. 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.
