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).

ACEBE5 SH - Overview

Interstate Plastics is proud to carry Delrin®, an industry-trusted name for acetal homopolymer. Delrin® is a tough, machinable thermoplastic with a high modulus of elasticity, high strength, good rigidity, dimensional stability, and resistances to moisture, chemicals and solvents. It has desirable toughness properties, performing well at extreme temperatures and under fatigue endurance. A low coefficient of friction (COF) alongside excellent wear properties, especially in wet or moist environments, makes Delrin® one of the most widely used engineering thermoplastics on the market today.

Low Moisture Absorption
Acetal plastics are ideal when working in wet environments as they absorb minimal amounts of moisture and, with a high level of heat resistance, can be heated or cooled without affecting form or dimensionality. Delrin® can be used in hot water applications up to 140°F without any hydrolysis effect. Unlike other materials that may erode form acidic water, hard water does not harm Delrin®.

High Strength & Stiffness
Delrin® is highly crystalline and due to its rigidity, resilience, toughness and strength, does not easily become brittle even with long-term exposure to unfavorable conditions including extremely high temperatures.

Easy to Machine
Delrin® is available in extruded rod and sheets for machined parts that are readily machined with standard machining practices. Any machining tool that is capable of high speed without vibration can be used.

Centerline Porosity
Centerline porosity is an inherent characteristic specific to Delrin® and occurs due to gassing during manufacturing. Centerline porosity can be found at the center or surface of all homopolymer extrusions. The porosity can cause problems in machining or moisture permeation through materials. Centerline porosity can also affect Delrin® products because it compromises structural integrity, presents potential routes for leakage of gas and liquids, and provides areas where bacteria can grow in food processing applications.
