How To Measure and Cut-To-Size Policy | Close it

Cut-To-Size Items are Non-Returnable!

As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under \"Comments\" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.

Measure Twice, Cut Once

Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.

How to Use a Measuring Tape

Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.

Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2\" has a bigger mark than 1/4\" which has a bigger mark than 1/8\". The smallest mark follows at 1/16\". Please be aware that some measuring tapes may have even smaller increments.

Features of a Measuring Tape: Sliding End Hook

The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

Description

Ultra-High Performance Metal Replacement for High Temperatures

PEEK (Polyether Ether Ketone) sheet is a versatile, high-performance thermoplastic known for its excellent chemical resistance, thermal stability, and fatigue resistance. It is recommended for demanding applications where extreme heat, pressure, and chemicals come into play.

PEEK has a maximum continuous working temperature of 480°F and is a reliable metal and stainless steel replacement in harsh environments. Robust mechanical and electrical properties allow it to perform effectively while serving as an alternative to metals and specialty materials in applications where weight reduction, corrosion resistance, and long-term performance are priorities.

Looking for enhanced structural properties? We also stock Glass-Filled PEEK and Bearing Grade PEEK for specialized high-load wear applications.

Why Choose This Specific Sheet?

PEEK is one of the most established high-performance engineering thermoplastics and is engineered to reduce the risk of failure in severe operating conditions. It is the correct choice if your application requires:

Extreme Temperature Resilience:
Maintains a continuous working temperature of 480°F and offers excellent retention of mechanical properties up to 570°F in steam or high-pressure water environments.
Broad Chemical Resistance:
Excellent resistance to a broad range of chemicals and hydrolysis; insoluble in most common solvents.
High Strength-to-Weight Ratio:
Lightweight compared to steel, aluminum, and titanium, while still providing excellent strength, stiffness, and dimensional stability.
High Wear Resistance:
Offers good wear resistance and sliding performance; bearing-grade PEEK may be preferred for demanding wear or PV applications.
Thermal Degradation Resistance:
Highly resistant to thermal breakdown, ensuring stable performance over an extended lifecycle.

PEEK vs. PTFE: Which Do You Need?

While both are high-performance plastics capable of withstanding extreme temperatures and harsh chemicals, their structural characteristics differ significantly.

  • Choose PEEK (This Sheet) if you require mechanical strength, stiffness, and the ability to bear heavy static or dynamic loads at elevated temperatures.
  • Choose PTFE if your application requires a very low coefficient of friction or outstanding chemical resistance, but does not rely on the material for structural support or high rigidity. PTFE is relatively soft in its unfilled form, though fillers can be added to improve rigidity, wear resistance, and dimensional stability.

Fabrication & Machining

PEEK is highly machinable but requires attention to thermal management. For high-tolerance components, use carbide or diamond-tipped sharp tooling and flood coolants.
