Is polycarbonate resistant to oil?
Polycarbonate is resistant to mineral acids, many organic acids, oxidizing and reducing agents, neutral and acid salt solutions, many greases, waxes and oils, saturated, aliphatic and cycloaliphatic hydrocarbons and alcohols, with the exception of methyl alcohol.
Is EPDM fuel resistance?
Ethylene-propylene diene monomer (EPDM) is valuable synthetic rubber for its excellent thermal aging and ozone resistance due to a highly unsaturated backbone. Nevertheless, it exhibits unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons due to nonpolarity.
Is Nitrile oil resistant?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
Is Santoprene oil resistant?
Results of these tests demonstrate that Santoprene rubber is inherently resistant to a wide variety of oils, solvents and chemicals. Santoprene rubber is not readily soluble in any common solvent, but will swell in aromatic solvents, halogenated organic solvents and hot petroleum oils.
What is the pH of polycarbonate?
Polycarbonate is synthesized mainly by interfacial polycondensation of bisphenol and phosgene [67]. Initially, bisphenol and phosgene are dissolved in aqueous and organic phase, and low pH values (9–11) are maintained to produce carbonate oligomers.
Can isopropyl alcohol damage polycarbonate?
Other chemicals such as Isopropyl Alcohol and Ethanol have very little effect on the surface of the Polycarbonate. However, the hard-coat will not protect against all chemicals and if there is a minor scratch in the hard-coat, chemicals can still attack at that point.
Is EPDM OK for oil?
EPDM is compatible with polar substances, e.g. fireproof hydraulic fluids, ketones, hot and cold water, and alkalis. It is incompatible with most hydrocarbons, such as oils, kerosene, aromatic compounds, gasoline, and halogenated solvents. EPDM exhibits outstanding resistance to heat, ozone, steam, and weather.
Is EPDM suitable for oil?
Operating Temperature Range. Resistance To Heat, UV, Oxygen, Ozone & Miscellaneous Chemicals….Which Elastomer Offers The Best Oil & Fuel Resistance?
| Elastomer | Oil Resistance | Fuel Resistance |
|---|---|---|
| EPDM | Poor | Poor |
| Natural Rubber | Poor | Poor |
| SBR | Poor | Poor |
What is difference between EPDM and Nitrile rubber?
What is the difference between NBR and EPDM? NBR and EPDM are two types of rubber materials. NBR stands for nitrile butadiene rubber, while EPDM stands for ethylene propylene diene monomer rubber. The main difference between NBR and EPDM is that NBR is a non-aromatic polymer compound while EPDM is an aromatic polymer.
Is Santoprene an EPDM?
Santoprene™ is a high performance thermoplastic elastomer (TPE). More specifically, Santoprene™ is a thermoplastic vulcanizate (TPV), meaning Santoprene™ is fully dynamically vulcanized EPDM (ethylene propylene diene monomer) rubber in a thermoplastic matrix of polypropylene (PP).
What is the difference between neoprene and Santoprene?
Both Neoprene and Santoprene TPV exhibit a high degree of chemical resistance. Conversely, Santoprene exhibits a poor performance against grease and oil while Neoprene fares better in the face of these substances. Both forms of synthetic rubber are resistant to oxidation and UV radiation.
What kind of chemical resistance does EPDM have?
It is the most economical choice of elastomer and has excellent all round chemical resistance to acids as well as alkalis, salts, alcohols and oxidizing chemicals. EPDM cannot be used on petroleum oils. The temperature range of EPDM is 70ºF – 300ºF [-57ºC – – 149ºC].
What kind of chemical resistance does polycarbonate have?
Polycarbonate is resistant to mineral acids, many organic acids, oxidizing and reducing agents, neutral and acid salt solutions, many greases, waxes and oils, saturated, aliphatic and cycloaliphatic hydrocarbons and alcohols, with the exception of methyl alcohol.
What kind of rubber is a NBR seal made of?
NBR is not resistant to solvents. This sealing ring is black and made of ethylene propene rubber. This is BLÜCHER’s standard sealing ring and it is suitable for all rainwater and waste water installations where there is no oil or no petrol residues in the waste water.
Is the NBR lip seal resistant to solvents?
The NBR lip seal should not be used where there is a risk of temperatures above 80ºC. NBR is not resistant to solvents. This sealing ring is black and made of ethylene propene rubber.
