937.299.2782 Home About Us Contact Us RFQ OVER 50 YEARS OF CUSTOM MOLDING EXPERTISE Capabilities Markets Served Projects Resources CUSTOM ELASTOMER COMPOUNDING Previous Next A CHOICE OF HIGH CONSISTENCY AND LIQUID SILICONE C & M Rubber Co. has a longstanding business relationship with many HCR Solid Silicone rubber and LR Liquid Silicone rubber suppliers, including Wacker, Momentive, Dow Corning, and Valley Rubber. Each vendor has a library of silicone compounds to draw from that will meet most if not all material specifications. Using the elastomer of your choice, C & M Rubber Co. has the in-house capability to mix a silicone compound or contract with a supplier to mix the compound for your specific application. This choice is driven by monthly quantity required and locking in the most advantageous price. COLOR MATCHING, DUROMETER, TEMPERATURE RESISTANCE C & M Rubber Co. can color match the Pantone© Formula Guide. We can also produce a custom compound with the durometer (hardness) granularity to ±5 points. With 53 years of experience, we have cataloged a wide breadth of knowledge in developing compounds that can tolerate wide ranges of temperature, tear resistance, and compression set. From one pound to fifty-pound batches, C & M Rubber Co. can recommend and mix just the right elastomeric compound for your application. UL/ NSF CERTIFICATION For applications that require qualified elastomers, C & M Rubber Co. will assist your organization in processing the required documents to apply for UL and /or NSF Certification.

Even under extreme heat, these compounds provide superior tensile strength, elongation and abrasion resistance. Low Temperature Despite extreme temperatures as low as -100°F, most silicone elastomers retain durometer and modulus. Special grades have brittle points below -150*F and remain serviceable at temperatures as low as -130°F. Compression Resistance Silicone elastomers offer incomparable resistance to compression set deformation, even at temperatures as low as -120°F or as high as 500°F. Electrical Properties Silicone elastomers provide unequalled electrical properties over a wide range of temperatures. The rival mica in terms of resistance to high-voltage ionization and corona. Plus, they show far less dielectric fatigue than TFE resins or organic elastomers. Fire Resistance Underwriters Laboratory Flame Test (UL94) is the standard measure of a materials resistance to burning. This UL test is performed on a test sample 5" x 1.2". A 3/4" Bunsen flame is applied for 10 seconds to a vertically supported sample immersed 3/4" into the flame. The time for burning to cease following the initial 10 second exposure is noted. The flame is applied again for 10 seconds and the time for burning to cease including glowing is noted. A total of 5 samples are tested in this manner. 5 additional samples aged for 7 days at 70°C are also tested in this manner. UL Flame Test Ratings and Results 94 V-0: 5 specimens with 10 flame applications, with none exceeding 10 second flame or 50 second total burn. 94 V-1: 5 specimens with 10 flame applications, with none exceeding 30 second flame or 250 second total burn. 94 V-2: Same criteria as for 94 V-1, except some dripping is allowed. 94 V-HB: 3 specimens none of which has either a burn rate exceeding 3 inches per minute or ceases to burn before reaching reference point. Smoke Generation Silicone polymers yield low levels of smoke under normal service or fire conditions. Radiation Resistance At room temperature, silicone elastomers outperform TFE resin and conventional fluoroelastomers on exposure to 10/8 roentgens.
