NEW ‘Y’ ELASTOMER INCREASES THE SERVICE LIFE OF THE PROVEN ARCUSAFLEX COUPLING BY 7-TIMES Published on 28 November 2017 - category Product. Successful Initial Use in a Combined Heat and Power Plant: Highly Stress Resistant 'Y' Rubber Compound from REICH Increases the Life of Arcusaflex Couplings in Thermally Critical Applications. REICH has usually employed silicone rubber for highly flexible power transmission components to be used at high temperatures. This silicone rubber type is listed as 'X' compound and suitable for temperatures up to +120 °C, or in some cases up to +130 °C. This material, however, has limited mechanical properties and tends to heat up additionally under extreme conditions including operation close to resonance speed. This can lead to earlier-than-expected overloads and failures. This is why the 'Y' rubber compound has been developed for high temperatures and specific operating conditions. The 'Y' elastomer is extraordinarily heat-resistant and can be used at service temperatures from –25 °C to +120 °C. The new 'Y' elastomer was employed for the first time in 2014 in a combined heat and power (CHP) plant of a central purification plant where an Arcusaflex coupling with a standard elastomer made of natural/synthetic rubber compound had originally been in use ‑ the right choice for a temperature range from –40 °C to +80 °C. But the temperatures occurring directly at the coupling were actually higher, last but not least due to the specific mode of operation of the CHP plant, so that initial incipient cracks began to show in the rubber disc coupling after just 3,000 hours of operation.
