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).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
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.

Works great in cold weather, very durable with no cracking or other problems for over two years now. We just re-ordered for a new project and I wanted to leave a review per the great customer service Bruce provided us and all the help from the folks at Interstate Plastics.

Expensive! Good, but expensive. Thought this would be a lot cheaper. The delrin is real high quality with reasonable in-transit time.

This was my first time ordering from your site and I was quite impressed. Easy to find what I was looking for and the cut to size calculator made my shopping experience even better. I will visit again for my next plastic purchase

I bought this to work on for my genesis coil set up, make sure that you are careful to not let it touch as the as the average dry coil temp is 500!! Material came quick and customer service was awesome :)
