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 OnceSince 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 TapeExtend 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 HookThe 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).
Interstate Plastics is proud to carry Ultem® (PEI), an amorphous polymer that offers outstanding elevated thermal resistance, high strength and stiffness, rigidity and creep resistance. Ultem® is commonly used in the medical field due to its heat and radiation resistance, hydrolytic stability and transparency. It is used to make burn-in sockets, bobbins, printed circuit substrates, automotive lamp sockets and under-hood temperature sensors, and PEI plastics sheeting is used in aircraft interiors. Transparency Heat & Radiation Resistance Strength & Stiffness Environmental Stress & Crack Resistance
Ultem® resin is widely carried in numerous transparent and opaque colors and special effects. Ultem® is also available in glass-filled grades with enhanced strength and stiffness. p>
Due to its amorphousness, Ultem® has no true melting point. Ultem® offers excellent stability of physical and mechanical properties at elevated temperatures due to a high glass transition temperature of 217°C. It comes available with relative thermal indices (RTI) that reach up to 180°C. Ultem® also offers inherent flame resistance without additives in most grades.
With average stiffness and strength up to 200°C, outstanding strength and thermoplasticity make it one of the best polysulfone alternatives on the market today. Ultem® is often used in place of polysulfone in applications where superior strength, stiffness and temperature resistance are required. Unfilled, transparent grades are equal in strength to other thermoplastics with pacifying fillers.
Compared to many other amorphous thermoplastics, Ultem® products retain strength and resist stress cracking when exposed to automotive and aircraft fluids, aliphatic carbonate, alcohols, acids and weak aqueous solutions. Its environmental stress and crack resistance make it an excellent plastic for any outdoor condition.
