Denka Chloroprene M-130L

Chloroprene rubber (CR), a synthetic material, is a common choice for making timing belts because of its good physical and chemical traits. Neoprene timing belts resist aging well and work best in regular transmission systems, but some situations might need different materials. 1. Aging resistance of chloroprene rubber timing belts Neoprene resists oxidation well, helping timing belts stay flexible and strong during regular use. This prevents the material from getting fragile or breaking down due to oxidation, making it good for machines exposed to air for extended periods, as it reduces the possibility of cracks or surface hardening. Heat resistance: The operating temperature range is generally between -20°C and 100°C, and it can operate for a long time in a medium-high temperature environment; under high temperature conditions, although its performance will decrease slightly, the aging process can be delayed by adding heat-resistant agents. Anti-ultraviolet performance: Neoprene has moderate anti-ultraviolet ability, but the surface may oxidize under long-term exposure to strong light, resulting in color changes and the formation of tiny cracks. Moisture resistance: Neoprene has good resistance to moisture and is suitable for high humidity environments. It is not easy to deteriorate due to moisture intrusion. Chemical corrosion resistance(Chloroprene Rubber SN-236T): It has good corrosion resistance to grease, weak acid, alkali and some chemical solvents, which slows down the aging rate, but is not suitable for contact with strong oxidizing chemicals.   2. Applicable scenarios of chloroprene rubber timing belts Industrial transmission equipment(Chloroprene Rubber SN-244X): Applicable to power transmission of conventional mechanical equipment, such as textile machinery, packaging equipment and general processing equipment. Medium temperature environment: It performs well in medium and high temperature (below 100°C) application scenarios, such as industrial drying equipment or HVAC systems. Indoor environment: Equipment with low requirements for UV resistance, such as indoor automation equipment or low maintenance systems. Medium humidity and chemical environment: It can be applied to equipment that contacts oils and weak acid and alkali environments, such as food processing machinery and light chemical equipment.   3. Limitations of aging resistance of chloroprene rubber timing belt Prolonged exposure to temperatures above 100°C can speed up the aging process, leading to reduced flexibility or hardening of the timing belt. When working in such conditions, fluororubber or silicone rubber belts are the preferred choice. Extended exposure to strong sunlight can cause surface oxidation and cracking, which reduces the lifespan of the belt. Polyurethane belts or those with anti-UV coatings are advisable for outdoor setups. Strong acids, bases, or concentrated chemical solvents can cause corrosion if the material isn't resistant enough.   4. Methods to extend the aging resistance of chloroprene rubber timing belts Reasonable storage: Store in a dry, ventilated, light-proof environment to avoid ultraviolet radiation and high temperature. Regular inspection: Regularly check whether there are cracks or hardening on the surface of the timing belt during use, and remove oil and chemical residues in time. Adding antioxidants: By adding antioxidants or anti-ultraviolet ingredients during the manufacturing process, the aging resistance of the timing belt can be significantly improved. Optimize working conditions: Avoid running the synchronous belt under excessive tension or extreme temperature to reduce the risk of aging.   Chloroprene rubber synchronous belts resist oxidation, heat, and moisture well, so they age slowly and work for many standard jobs. Still, they might not work as well when it's very hot, there's a lot of ultraviolet light, or things are very corrosive. You can make these belts last longer by storing and using them properly and keeping up with regular maintenance. Because of this, they're a solid, affordable choice.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com  

1. Research and development of chloroprene rubber Chloroprene rubber & Neoprene latex is famous for its weather resistance, excellent physical properties, chemical resistance and oil resistance. Therefore, chloroprene rubber is widely used in rubber accessories that are exposed to the air and require oil resistance and high mechanical properties, such as: hoses, conveyor belts, transmission belts, cable sheaths, dust covers, shock pads, air capsules and other rubber products that require weather resistance, oil resistance, high physical properties and good flexural properties. The trade name of LANXESS chloroprene rubber is Baypren, which is translated into Bayer Ping in Chinese. It evolved from the original Perbunan C of Bayer Company and was produced in the Dormagen factory in Germany. 2. Trade names and naming principles of LANXESS chloroprene rubber Trade names of LANXESS chloroprene rubber LANXESS chloroprene rubber has a variety of brands to meet the needs of different products and different application environments. For specific brands, please refer to the LANXESS rubber product brand table. The main varieties of Lanxess nylon-butadiene rubber currently sold in China are: Baypren126 is a molded grade, which is resistant to high and low temperatures, has good physical and mechanical properties, excellent process, and does not burn or stick to rollers. Baypren 116 has a lower Mooney viscosity than Bapren126, and the rubber compound has good fluidity. It is a grade for extruded products, with stable extruded dimensions, smooth surface, and high efficiency. Baypren711 is a vulcanization-adjustable grade, used for adhesive tapes. It has a high sulfur content, good processability of the rubber compound, good adhesion to reinforcing materials, and is wear-resistant. Baypren 210 is a universal brand. It has excellent comprehensive performance and meets the processing requirements of different processes and products. The price is relatively low. Baypren 230 (SN-238) is an extra-high Mooney grade with high mechanical strength. It is suitable for high strength and blending with other grades to achieve special product performance and process requirements. Baypren 114 is a pre-crosslinked grade. It is suitable for extruding high-performance thin-walled and precise-size products, and the extruded products are resistant to collapse. Such as continuous vulcanization production of automotive wiper strips and other products and processes. Naming principles of LANXESS chloroprene rubber LANXESS chloroprene rubber consists of a product name plus a 3-digit number. The product name is: Baypren, which is translated as Bayer Ping. The brand name is represented by a 3-digit number, and Baypren 126 is used as an example as follows: The first digit indicates the crystallization tendency, 1 slight/2 medium/3 strong crystallization (general brand); sulfur content, 5 low sulfur/6 medium/7 high sulfur (sulfur-adjusted brand). The second digit indicates the Mooney viscosity: 1 low Mooney/2 medium/3 high Mooney. The third digit indicates special properties: 4 pre-crosslinking; 5 pre-crosslinking plus xanthogenic acid disulfide adjustment; 6 xanthogenic acid disulfide adjustment. The third digits 1 and 2 indicate the Mooney viscosity of the raw rubber and the tendency to form products. For example, the crystallinity of Baypren 111 is extremely low, while the crystallinity of Baypren 112 is low to moderate.   3. Future Development 1)The high-tech development of automobile products and the strengthening of safety, hygiene and environmental protection concepts have caused fundamental changes in rubber materials. Many general-purpose products will inevitably be replaced by special brands to adapt to their special properties.  2) Modern rubber equipment is becoming more and more advanced and efficient, forcing the manufacturing process to be more and more perfect. Many product processes have consciously or unconsciously shifted from the original molding method to the injection method. This has led to an increase in demand for rubber compounds with good performance, long scorch time, and non-stick rollers. More attention is paid to injection rubber compounds with good fluidity. Lanxess's special Mooney rubber compound (Mooney can reach as low as 28 Mooney) chloroprene rubber brand was developed for this purpose. 3) The development of high-precision and cutting-edge technology requires many products with extremely high physical properties and low temperature resistance. In this regard, LANXESS already has a variety of special-functional chloroprene rubber grades available for selection, which need to be developed and utilized in combination with their functional requirements during product design and development, and explore newer and more scientific uses.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
