OEM PEEK high temperature Injection Molded Parts

Defining the Gold Standard in High-Performance Polymers

Polyetheretherketone (PEEK) represents the ultimate frontier in high-performance thermoplastics, engineered to operate where conventional materials cannot survive. Our PEEK injection molded components deliver unparalleled performance in the most demanding thermal, mechanical, and chemical environments across aerospace, medical, energy, and semiconductor industries. As a semi-crystalline thermoplastic in the polyaryletherketone (PAEK) family, PEEK maintains exceptional properties at continuous temperatures up to 260°C (500°F) while offering chemical resistance comparable to specialty metals.

PEEK's unique molecular structure – featuring a backbone of aromatic rings linked by ketone and ether groups – provides an extraordinary combination of properties typically associated with metals: high strength-to-weight ratio, excellent wear characteristics, and inherent flame retardancy without halogen additives. These capabilities make PEEK the material of choice for mission-critical applications where reliability is non-negotiable and failure carries extreme consequences.

Unrivaled Material Properties for Extreme Applications

Exceptional Thermal Performance

PEEK operates continuously at temperatures up to 260°C (500°F) with short-term exposure to 310°C (590°F). The material maintains its mechanical properties across this entire range, outperforming all conventional thermoplastics and competing with many metals. Its glass transition temperature of 143°C (289°F) and melting point of 343°C (649°F) enable performance in environments where other polymers would soften or decompose.

Superior Mechanical Strength and Stability

Even at elevated temperatures, PEEK retains impressive mechanical properties with tensile strength of 90-100 MPa and flexural modulus of 3.6-4.0 GPa. Carbon-fiber reinforced grades increase these values to 200+ MPa tensile strength and 15+ GPa flexural modulus, rivaling some aluminum alloys while offering 70% weight reduction.

Outstanding Chemical and Radiation Resistance

PEEK demonstrates exceptional resistance to a wide range of chemicals, including acids, bases, hydrocarbons, and steam. It withstands exposure to gamma radiation and electron beam sterilization, making it ideal for medical and nuclear applications. Unlike metals, PEEK is completely immune to galvanic corrosion.

Excellent Wear and Friction Properties

With natural lubricity and excellent resistance to abrasive wear, PEEK performs exceptionally in bearing and sealing applications. When combined with internal lubricants like PTFE, graphite, or carbon fiber, the coefficient of friction can be reduced to levels comparable to oil-impregnated bronze bearings.

Inherent Flame Resistance and Low Smoke Emission

PEEK achieves UL94 V-0 flame rating without halogenated additives and produces minimal smoke and toxic gas when exposed to flame. This combination makes it indispensable for aerospace, mass transit, and other applications with stringent fire safety requirements.
