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

High-Temperature UHMW Rod for Machined Parts

TIVAR® H.O.T. (Higher Operating Temperature) rod is engineered for fabricating cylindrical components that must endure high heat. Formulated with specialized additives to resist oxidation, this UHMW rod operates in environments up to 275°F—outperforming standard UHMW-PE by nearly 100°F.

When machined into rollers, bearings, or sprockets, TIVAR® H.O.T. resists thermal degradation and extends part life up to 10 times longer than standard plastics in thermo-cycling applications, all while maintaining its signature low friction and wear resistance.

Don't need extreme heat resistance? If your machined components operate below 180°F, explore our Natural Virgin UHMW Rod for a cost-effective, FDA-compliant alternative.

Why Fabricate with TIVAR® H.O.T. Rod?

Engineered to excel in the "Heat Zone," this rod stock is ideal for turning and milling parts used in high-temp food processing and packaging lines. Choose this material when you require:

275°F Thermal Limit:
Maintains structural integrity and wear properties well past the 180°F threshold of standard UHMW rod.
Oxidation Defense:
Resists thermal degradation in baking and thermo-cycling environments to prevent premature part failure.
FDA Compliance:
Meets FDA requirements for use in high-temperature sanitation and food processing applications.
Extended Part Longevity:
Turned parts outlast standard plastics by up to 10x in high-heat environments.
Washdown Ready:
Very low moisture absorption combined with strong resistance to many caustic cleaning chemicals.

TIVAR® H.O.T. vs. Standard UHMW: Which Do You Need?

While both materials share the same extreme wear resistance and low-friction properties that characterize UHMW, their thermal limits define their ideal environments.

  • Choose TIVAR® H.O.T. (This Rod) to machine custom rollers, high-temp bearings, pulleys, and sprockets for baking ovens, dehydrators, or chemical washdown systems. It is essential when your parts will face continuous operating temperatures exceeding 180°F.
  • Choose Natural Virgin UHMW Rod for general-purpose turned parts, guide pins, and rollers in ambient temperatures. It provides similar impact strength and sliding abrasion resistance at a lower cost for non-thermal environments.

Turning & Machining

TIVAR® H.O.T. rod turns exceptionally well on CNC lathes and can be milled using standard metalworking equipment. While it drills and cuts cleanly, its low friction surface and thermal expansion properties mean coarse threads are recommended if tapping or mechanical fastening is required.
