What is the difference between EPDM and FKM?
What is the difference between EPDM and FKM?
EPDM (EP, EPR, Ethylene-Propylene Rubber) Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures.
Is polypropylene compatible with sulfuric acid?
Description: Polypropylene resins, like most polyolefin resins, are highly resistant to solvents and chemicals. They are appreciably affected by strong inorganic acids such as fuming nitric acid at room temperature and 98% sulfuric acid at 600C.
Is EPDM good for glycol?
A = Excellent. B = Good. Minor Effect. Slight corrosion or discoloration….Guide to Impact of Chemicals on EPDM Rubber.
| Chemical | Compatibility |
|---|---|
| Ethylene Chlorohydrin | B-Good |
| Ethylene Diamine | A-Excellent |
| Ethylene Dichloride | C-Fair |
| Ethylene Glycol | A-Excellent |
Is FKM and Viton the same?
These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.
Is Viton better than FKM?
Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same.
What will dissolve polypropylene?
At elevated temperature, polypropylene can be dissolved in nonpolar solvents such as xylene, tetralin and decalin.
What plastic can withstand sulfuric acid?
1. PTFE (or Teflon™) – PTFE, also commonly known as Teflon™, is one of the most acid resistant materials available and is commonly used in chemical and pharmaceutical lab applications.
Does h2so4 react with plastic?
Storage Challenges Sulfuric acid presents serious storage issues because it’s a very heavy chemical, especially at high concentrations. At 93-98% concentration, it is nearly twice the weight of water. It’s also an aggressive chemical that oxidizes plastic and corrodes metals.
What is the difference between TPO and EPDM?
TPO roofing reflects sunlight, allowing commercial air conditioners to work more efficiently; whereas EPDM has a dark surface, which in summer conditions will absorb heat, forcing cooling systems to work overtime. TPO offers reduced cooling costs and energy savings for facilities located in warmer climates.
