Neoprene Latex

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  

Gloves are the most commonly used protective tools in the laboratory besides goggles. There are many types of gloves, and different gloves have different uses.     1. Natural rubber (latex) Latex gloves, made from natural rubber, typically lack a lining and are available in both clean and sterile versions. These gloves can provide effective protection against alkalis, alcohols, and a variety of chemical dilution aqueous solutions, and can better prevent corrosion from aldehydes and ketones.   2. Polyvinyl chloride (PVC) gloves The gloves do not contain allergens, are powder-free, have low dust generation, low ion content, strong chemical corrosion resistance, can protect almost all chemical hazardous substances, and also have anti-static properties. Thickened and treated surfaces (such as fleece surfaces) can also prevent general mechanical wear, and thickened types can also prevent cold, with an operating temperature of -4℃ to 66℃. Can be used in a dust-free environment. PVC gloves grading standards: Grade A products, no holes on the surface of the gloves (PVC gloves with powder), uniform powder, no obvious powder, transparent milky white color, no obvious ink spots, no impurities, and the size and physical properties of each part meet customer requirements. Grade B products, slight stains, 3 small black spots (1mm≤diameter≤2mm), or a large number of small black spots (diameter≤1mm) (diameter>5), deformation, impurities (diameter≤1mm), slightly yellow color, serious nail marks, cracks, and the size and physical properties of each part do not meet the requirements.   3. PE gloves PE gloves are disposable gloves made of polyethylene. These gloves are waterproof, oil-proof, anti-bacterial, and resistant to acids and bases. Note: PE gloves are safe to use with food and are non-toxic. It is better to keep PVC gloves away from food, especially if it's hot.     4. Nitrile rubber gloves Nitrile rubber gloves are usually divided into disposable gloves, medium-duty unlined gloves and light-duty lined gloves. These gloves can prevent erosion by grease (including animal fat), xylene, polyethylene and aliphatic solvents; they can also prevent most pesticide formulations and are often used in the use of biological components and other chemicals. Nitrile rubber gloves do not contain protein, amino compounds and other harmful substances, and rarely cause allergies. They are silicone-free and have certain antistatic properties, which are suitable for the production needs of the electronics industry. They have low surface chemical residues, low ion content and small particle content, and are suitable for strict clean room environments.   5. Neoprene gloves Similar to the comfort of natural rubber, neoprene gloves are resistant to light, aging, flexing, acid and alkali, ozone, combustion, heat and oil.   6. Butyl rubber gloves Butyl rubber is only used as a material for medium-sized unlined gloves and can be used for operations in glove boxes, anaerobic boxes, incubators, and operating boxes; it has super durability against fluoric acid, aqua regia, nitric acid, strong acids, strong alkalis, toluene, alcohol, etc., and is a special rubber synthetic resistant liquid gloves.   7. Polyvinyl alcohol (PVA) gloves Polyvinyl alcohol (PVA) can be used as a material for medium-sized lined gloves, so this type of gloves can provide a high level of protection and corrosion resistance against a variety of organic chemicals, such as aliphatic, aromatic hydrocarbons, chlorinated solvents, fluorocarbons and most ketones (except acetone), esters and ethers.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
