For outdoor environments, you should choose EPDM. Nitrile suits oil and fuel contact best. For mixed chemical resistance, select neoprene and chloroprene. Evaluate your project’s environmental exposure, chemical compatibility, and temperature requirements. These factors will help you make the right material choice for reliable, long-term performance.   1. Comparison Overview   Key Properties When you compare Chloroprene Rubber(such as Polychloroprene Rubber CR2440) , EPDM, and Nitrile Rubber, you need to focus on several critical properties. These include oil resistance, weathering, ozone/UV resistance, fire performance, temperature range, and cost. The table below summarizes how each material performs in these areas: Property Property Chloroprene Rubber EPDM Nitrile Rubber Oil Resistance Moderate Poor Excellent Weather Resistance Excellent Excellent Fair-Good Ozone/UV Resistance Poor Fair-Good Good Temperature Range (°F) -40 to 225 -60 to 300 -40 to 250 Cost Moderate Low-Moderate Moderate   Ozone and Weathering Resistance Table Rubber Type Ozone Resistance Weather Resistance Chloroprene Rubber Poor Excellent EPDM Fair-Good Excellent Nitrile Rubber Good Fair-Good   Fire Resistance Classification Table Material Fire Resistance Classification Chloroprene Rubber Not a fire retardant, but less flammable than other commercial rubbers; melts when aflame but can be extinguished. EPDM Good level of flame resistance; requires compounding with blockers to meet fire standards. Nitrile Rubber Not rated   2. Pros and Cons You should weigh the advantages and disadvantages of each material before making your selection. Chloroprene Rubber Pros: Offers balanced resistance to oil, chemicals, and weathering; Performs well in outdoor and marine environments; Less flammable than many other rubbers. Cons: Faces supply chain risks due to regulatory restrictions; Ozone resistance is lower than EPDM or Nitrile; Cost can be higher than EPDM. EPDM Pros: Excels in outdoor, UV, and ozone-exposed applications; Maintains flexibility at low temperatures; New formulations provide flame resistance and self-healing properties; Cost-effective for large-scale projects. Cons: Poor resistance to oils and fuel; Requires additives for optimal fire performance; Not suitable for applications involving petroleum-based fluids. Nitrile Rubber Pros: Outstanding oil and fuel resistance; Enhanced heat resistance in modern compounds; Can be blended for specialized performance, such as static dissipation; Eco-friendly options are emerging. Cons: Weathering and ozone resistance are lower than EPDM; Not inherently flame retardant; Flexibility decreases at low temperatures.   3. Choosing the Right Material Environmental Factors You need to assess the environment where your rubber material will operate. Outdoor exposure, sunlight, ozone, and weathering can quickly degrade some rubbers. EPDM stands out for its excellent resistance to ozone and sunlight, making it the top choice for outdoor applications. You benefit from EPDM’s ability to withstand harsh weather, UV rays, and temperature swings. This material can last up to 20 years or more in outdoor conditions. If your project involves exposure to oils or solvents, Chloroprene Rubber (such as Neoprene AD-20) offers good oil resistance and performs well in parts exposed to chemicals. EPDM is also more environmentally friendly because it is non-toxic and recyclable, while Neoprene (Chloroprene Rubber) is less sustainable.   Chemical Resistance You must match the rubber’s chemical resistance profile to your application. Each material reacts differently to oils, fuels, and industrial chemicals. Nitrile Rubber provides high oil resistance but performs poorly against weather and ozone. Chloroprene Rubber offers moderate oil resistance and excellent weather resistance. EPDM does not resist oils but excels in weather and ozone resistance. Rubber Type Oil Resistance Weather Resistance Flame Resistance Ozone Resistance Nitrile Rubber High Poor Poor Poor Chloroprene Rubber Moderate Excellent Very Good Excellent EPDM N/A Excellent N/A Excellent You should always check the chemicals your project will encounter. Select Nitrile Rubber for oil and fuel contact. Use Chloroprene Rubber for balanced resistance to chemicals and weather. Choose EPDM for applications with no oil exposure but high weathering demands.   4. Summary Choosing the right rubber material for your project depends on matching its properties to your application’s demands. You need to consider oil resistance, weathering, ozone and UV exposure, and the specific environment where the rubber will perform. Each rubber type offers unique strengths that make it ideal for certain uses.   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
