Featured Material: PEEK (Polyetheretherketone)

Piper Plastics has become the world leader in providing cost effective finished parts and assemblies from Polyetheretherketone (PEEK). This relatively new high performance material is the fastest growing plastic material of choice in the Semiconductor, Medical, and Aerospace/Defense industries. PEEK's high strength, high temperature resistance, and superior chemical resistance have contributed to the successful replacement of metal, glass, ceramic, and more expensive polymers such as Vespel.

Piper Plastics machines and assembles tight tolerance PEEK components and remains the industry leader in PEEK welding, bonding, and other fabrication techniques. Ask Piper to quote your PEEK parts using our proprietary and cost-effective near net shape molding and machining techniques.

Important Characteristics of PEEK™

High Temperature Performance
A continuous service temperature (UL746B method) of up to 260°C (500°F) with excellent electrical and mechanical properties retained. HDT of up to 315°C for reinforced grades.

Strength & Toughness
Exceptionally high strength properties combined with good toughness over a wide range of temperatures.

Chemical Resistance
Insoluble in most common solvents and being semi-crystalline has excellent resistance to a very wide range of organic and inorganic liquids, at elevated temperatures.

Wear Resistance
Excellent friction and wear properties over a wide range of pressure, velocity, temperature and counterfacial roughness.

Purity
Inherently pure with exceptionally low levels of ionic extractables and excellent outgassing characteristics.

Radiation Resistance
Resistance to gamma radiation at high dose levels is exceptional.

Low Flammability
UL V-O flammability rating down to 1.45 mm (0.057) without the use of additives.

Low Smoke and Toxic Gas Emission
The composition and inherent purity of the materials results in extremely low smoke and toxic gas emission in fire situations.

Hydrolysis Resistance
Can be used for thousands of hours at elevated temperatures in excess of 250°C (482°F) in steam or high pressure water environments without significant degradation in properties.

Electrical Properties
Remains stable over a wide range of temperatures and frequencies.

Processing
Easily processed using a wide range of conventional thermoplastic processing equipment.
