PEI (Polyetherimide) is a high-strength amorphous polymer often branded as ULTEM.

Characterized by excellent heat and flame resistance with a flammability rating of 94-V-0, ULTEM can perform continuously up to 340°F (171°C). ULTEM is also hydrolysis resistant, as well as highly resistant to most acidic solutions.

Additionally, ULTEM has one of the lowest thermal conductivity ratings and the highest dielectric properties of thermoplastic materials, outperforming both Nylon and DELRIN.

Characterized by excellent heat and flame resistance, ULTEM has the highest dielectric strength of any thermoplastic.

ULTEM is commonly used for a variety of structural components requiring high strength and rigidity at elevated temperatures.

PPS (Polyphenelynesulfide) offers the broadest resistance to chemicals of any advanced engineering plastic.

Several grades of PPS exist, including RYTON (Unfilled or Bearing-Grade) and TECHTRON (Unfilled, 40% Glass-Reinforced or High-PV). Additional grades include SUSTATRON (Unfilled or 40% Glass-Reinforced) and TECATRON (Unfilled, Bearing-Grade or Hydrolysis-Resistant).

These various grades of the PPS resin allow for chemical resistance, high temperature stability, zero moisture absorption, excellent dimensional stability, ultra-low wear factors and structural strength. PPS materials also offer low flammability ratings of V-O/5VA.

PAI (PolyamideImide) is the highest performing, melt-processible plastic, built from TORLON Resin. TORLON materials maintain strength and stiffness to 500°F (260°C), have excellent wear resistance and are able to endure harsh thermal, chemical and stress conditions.

There are several TORLON grades available for PAI, including TORLON 4203 (electrical and high strength), TORLON 4301 (general purpose wear), TORLON 4XG (glass-reinforced) and TORLON 4XCF (carbon-reinforced).

The compressive strength of TORLON PAI (unfilled) is double that of PEEK, and about 30% higher than that of ULTEM PEI. However, special engineering attention should be used when designing TORLON components in wet environments, as its moisture absorption rate is not as low as other high performance plastics.

PSU (Polysulfone) is an amber semi-transparent, heat-resistant, high performance thermoplastic made from UDEL Resin.

Offering above-average mechanical and electrical properties, as well as improved chemical resistance properties, UDEL PSU is able to retain its properties in temperatures ranging from -150°F (-100°C) to 300°F (150°C).

Additionally, PSU has excellent radiation stability and maintains high resistance to acidic and salt solutions, is hydrolysis-resistant for continuous use in hot water and steam at temperatures up to 300°F (150°C) and its flame resistance is UL 94-V-0 at 1/4th inch thickness (6.35mm) and UL 94-V-2 at 1/8th inch thickness (3.175 mm).

PSU 1000 is a suitable replacement for PC 1000 (Polycarbonate) in higher temperatures or when improved chemical resistance is required.

In many applications, UDEL PSU is preferred over stainless steel parts or aluminum as the material is 7 times lighter than stainless steel and can also be steam-cleaned in areas like chemical labs.

PPSU (Polyphenylsulfone) is an amorphous high performance thermoplastic made from RADEL R Resin.

Offering improved impact and chemical resistance over Polysulfone (UDEL) and Polytherimide (ULTEM), this material has also been tested for notched izod impact resistance as high as 13 ft.-lbs/in.

The impact resistance, coupled with a heat deflection temperature of 405°F (207°C) and virtually unlimited steam auto clave resistance, make RADEL R PPSU the material of choice for many reusable medical components.

RADEL R PPSU is FDA and NSF-compliant under standards 51 and 61.

PEEK (PolyEtherEtherKetone) comes in several different grades, each offering excellent chemical and hydrolysis resistance. Very similar to PPS, PEEK has inherently good wear and abrasion resistance, but outshines PPS with its ability to be used continuously to 480°F (250°C). PEEK carries a V-O flammability rating, exhibits very low smoke and toxic gas emission when exposed to flame and is available in several different grades.

PEEK does not operate as well as PAI or PBI at extreme temperature (above 500°F, 260°C), but it is a much better choice in situations requiring chemical resistance, steam resistance or a low moisture absorption rate.

A wide range of extruded and compression molded shapes and sizes are available for machining.

Acetal (Polyoxymethylene) is a semi-crystalline material that provides high strength and stiffness while maintaining a low coefficient of friction and good wear properties in wet environments. Excellent for high moisture or submerged applications, Acetal significantly outperforms Nylon in these environments.

Acetal also has a high resistance to a variety of chemicals and is used for electrical insulators, industrial bearings, rollers, gears and scraper blades. However, unmodified Acetal does not perform as well as nylons in general abrasive wear applications.

Several different grades of Acetals are available: PTFE-filled Acetals with lower coefficients of friction (ideal where impact strength and wear capability are needed), glass-reinforced Acetals with a much higher strength and greater heat resistance and FDA-compliant Acetals for medical- and food-related applications.

An acceptable material for a broad range of general applications in the Aerospace & Defense, Medical and Power & Energy industries at temperatures below 250°F (121°C), there are a wide range of extruded shapes and sizes available for machining.
