5/2/2016· As Viton® properties are quite different from nitrile rubber properties. It is crucial to consider the pros and cons of both materials, specifically in the context of their appliion. You can also consult our chemical compatibility guides or call Polymax on 01420 472000 for more information. This entry was posted in Viton® O-rings, Nitrile
High-temperature tolerance— between 150°C (302°F) and 204°C (400°F) in water or steam)—makes EPDM an excellent steam hose, and it is also a great choice for conveying low and high pH fluid. However, EPDM is not oil resistant—thus unsuitable for fuel transfer hose—and can also be very costly. Nitrile Rubber (NBR)
EPDM rubber and natural rubber differ in the sense that EPDM is a 100% man-made material whereas NR is a plant-based material that is harvested. EPDM rubber sheeting is made of a blend of strengthening chemicals while natural rubber is made from the latex sap found in rubber trees. These different components used in their production gives each

Poor. Poor. For the best oil and fuel resistance, the options from the above are clearly Nitrile, Epichlorohydrin and Viton and on balance, all three elastomers will perform adequately in this environment. Nitrile is regarded as the ‘industry workhorse,’ a general commodity material which performs very well in environments where there is an
Multiple plies of synthetic textile. Cover: Grey EPDM. Length: 100 ft. WP 250 psi. Temperature Range: -40°F (-40° C) to +225° F (+116° C) (Cleaning In Place to 248° F (+120° C). Not for use with steam. EPDM Food Suction & Discharge Hose Novaflex 6400 Flexibile and rugged, built with a clean white FDA tube. This food grade EPDM hose is
14/1/2019· Both silicone and EPDM have a lower compression set, however. EPDM beats SBR in tensile strength and resistance to heat aging and weathering. Nitrile butadiene rubber (NBR): Nitrile is king of elastomers when it comes to oil- and fuel-resistance. One attraction to NBR is its stability in low temperatures, with the ability to survive extreme cold of -30˚C/ -22˚F, which …
The outer layer or cover is either Nitrile or EPDM but both are fine and the difference is small on the inner tube it makes more difference. There are three common "rubber" materials used in brewers hose, nitrile, butyl and EPDM. The two biggest differences are: 1) Temperature resisitance, * nitrile 180 F * butyl 220 F * EPDM 300 F
As an outdoor rubber, EPDM rolls are often used outdoors whereas nitrile rolls are generally used indoors. An EPDM elastomer is better able to withstand harsh environmental factors than nitrile making it the ideal outdoor rubber; however, nitrile rubber holds the upper hand when it comes to resisting oil, grease, and gasoline.
When compared with silicone rubber, EPDM is significantly inferior with a maximum temperature of 130°C (266°F). Silicone can reach constant temperatures of 230°C (446°F) and up to 270°C (518°F) for special high temperature silicone grades. Elongation is how stretchy a material is and how it performs when being expanded and contracted.
It’s easy to see why there’s some confusion. Both EPDM and silicone: Offer excellent weathering resistance. Are excellent as electrical insulators. Maintain flexibility down to around -50°C/-58°F. Stand up to some chemicals. To a varying degree, have great compression set. Are popular as water-system seals, O-rings, hoses and meranes.
EPDM Tubing. Custom Advanced offers EPDM tubing and EDPM hoses among many other types of rubber tubings. EPDM is a terpolymer of ethylene, propylene and a diene monomer making EPDM tubing an outstanding resistance to oxygen, ozone, and sunlight. It is resistant to polar materials such as phosphate esters, many ketones and alcohol.
3/3/2020· While NBR and FKM have similar chemical resistance, EPDM is completely different. It is incompatible with petroleum (oil and gasoline), but it is compatible with alcohols (ethanol, methanol, and nitromethane), water, and glycol-based fluids such as brake fluid. Click to see full answer. Similarly, it is asked, what does FKM material mean?
13/12/2019· Deceer 13, 2019. PGC converts materials like EPDM, neoprene and nitrile into custom gaskets for your appliions. We work with companies in the medical, heavy duty, fluid power, electronics, defense and aerospace industries. Our engineers will help you in the development process to ensure you have the highest quality and best performing part
In a nutshell, here are the primary differences: Weight - The rubber hose weighs twice as much as the polyurethane hose. This is most noticeable while pulling the hose out and reeling it back in. Durability - The outer cover on the polyurethane hose is made of the same material as the wheels on in-line roller skates.
17/10/2020· EPDM gaskets vs. TPE gaskets is a comparison that engineers who design environmental seals need to make. Ethylene propylene diene monomer (EPDM) and thermoplastic elastomers (TPE) both resist water, weather, ozone, and sunlight. These gasket materials also withstand a wide range of outdoor temperatures and are available in compounds that meet
21/4/2021· Due to this, while EPDM is used frequently in braking systems in vehicles, Nitrile finds better use in the fuel systems. Another difference between EPDM and Nitrile is that EPDM is an aromatic polymer but Nitrile, on the other hand, is non-aromatic. And when it comes to cost, Nitrile is the more expensive one out of the two.
Silicone. Excellent. Thermoplastic Elastomer. Excellent. Vamac. Excellent. Viton. Excellent. Whilst clearly faced with a nuer of options in terms of elastomers offering ‘excellent’ Ozone and weather resistance, the following examples showcase commonly used base materials which help to minimise the impact of harsh weather conditions upon a
15/2/2021· Steam hose, to an extent, runs the gamut when it comes to construction: there’s EPDM, nitrile in instances where oil resistance is needed, and chlorobutyl in more premium varieties, like when you need a hose that is going to stand the test of time. Most of these will handle temperatures north of 406°F for saturated steam and 450°F for
3/10/2021· Two common synthetic rubber compounds are known as EPDM and nitrile rubber. The main differences between these two rubber products are their resistance to petroleum-based fuels and lubricants and their resistance to weathering. The main difference between NBR and EPDM is that NBR is a non-aromatic polymer compound while EPDM is an aromatic polymer.
5/2/2016· Appliions: After NBR (nitrile) o rings are most commonly available in Viton® polymer which has excellent oil and chemical resistance and is used extensively in the petrochemical, chemical and food industries. EPDM is good in steam appliions and has moderate chemical resistance, but should be avoided with petroleum agents and solvents.
Ethylene-propylene compounds are prepared from ethylene and propylene (EPM) and usually a third monomer (EPDM). These compounds are used frequently to seal in brake systems, and for sealing hot water and steam. Ethylene propylene compounds have good resistance to mild acids, detergents, alkalis, silicone oils and greases, ketones, and alcohols.
EPDM’s properties make it a great choice for outdoor appliions because of its resistance to the effects of ozone, heat, and temperature. One example of a smart use for EPDM is the cover of a typical garden hose you might use at home. Appliions: Outdoors Products: Parker Dragon Breath hot air blower hose, Parker GST 11, Parker 7211 Super-Lok
23/1/2018· Key Difference – EPDM vs PVC EPDM (Ethylene Propylene Diene Monomer) and PVC (Poly-Vinyl Chloride) are widely used polymers owing to their unique set of properties. The key difference between EPDM and PVC is that the EPDM is a synthetic rubber, which is synthesized from petroleum byproducts whereas, PVC is a thermoplastic, which can be melted down at …
2 days ago· EPDM and silicone are two commonly used rubbers in industrial appliions, with silicone acting as a general use rubber while EPDM is more specialized. Here, we’ll be covering the basics of what EPDM and silicone rubber are, as well as their similarities and differences, to help you get a better grasp of which rubber works better for certain appliions.
5/6/2022· For certain appliions, EPDM is the cheaper option of the two rubbers. EPDM functions better in higher temperatures, with a maximum of 300-350 degrees F, while neoprene handles only up to 225 degrees F. It’s also steam resistant and more ozone resistant.
