| Chemical | Compatibility |
|---|---|
| Acetic Acid 80% | A-Excellent |
| Acetic Acid, Glacial | A1-Excellent |
| Acetic Anhydride | B1-Good |
| Acetone | A-Excellent |
Is polypropylene chemically resistant?
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 acetone compatible with plastic?
Not Recommended. If acetone comes into contact with the plastics below, you can expect a severe effect, especially at a high concentration and over a long time. The acetone will damage the plastic’s surface, softening it, smearing it, or even dissolving the plastic.
Is HDPE compatible with acetone?
While acetone will not dissolve HDPE, it can lead to material failure. If you leave acetone in a Nalgene bottle for long periods, it will eventually develop horizontal (i.e. circumferential) solvent-stress cracks at the level of the liquid-vapor interface, leading to failure when squeezed.
Does polypropylene react with isopropyl alcohol?
Most likely – yes. Making a test by putting a drop of IPA on the surface and waiting won’t hurt – not because of the health concerns, but to make sure it doesn’t damage the surface leaving a stain.
Does polypropylene react with ethanol?
Such nonpolar liquids as benzene, carbon tetrachloride, and petroleum ether have a higher absorption rate with polypropylene than polar media such as ethanol and acetone. HMC PP resins have excellent resistance to environmental stress-cracking.
Is polypropylene resistant to caustic?
Chemical resistance of Polypropylene – PP – to acids, bases, organic substances and solvents. PP (Polypropylene) is a polyolefin available in as homopolymer and co-polymer. PP has superior resistance to sulfur-bearing compounds and is capable of withstanding a wide range of corrosive and sanitary effluents.
Is polypropylene resistant to petrol?
Polypropylene copolymers swell more than homopolymers, indicating greater absorption. Such nonpolar liquids as benzene, carbon tetrachloride, and petroleum ether have a higher absorption rate with polypropylene than polar media such as ethanol and acetone.
Does hydrochloric acid dissolve polypropylene?
It resists most strong mineral acids and bases, but, like the other polyolefins, it is subject to attack by oxidizing agents. HMC PP resins are appreciably affected by chlorosulfonic acid and oleum at room temperature, 98% sulfuric acid, 30% hydrochloric acid, and 30% hydrogen peroxide at 100°C (212°F).
What’s the difference between polypropylene and polyethylene?
Polyethylene has a lower melting point compared to the higher melting point of polypropylene. Polypropylene is stiffer and resistant to chemicals and organic solvents compared to polyethylene. Polypropylene is pure, non-stretching and generally more rigid than polyethylene.
Is HDPE the same as polypropylene?
HDPE is high-density polyethylene while PP is polypropylene. Thus the key difference between HDPE and PP is that the HDPE is made with ethylene monomer whereas PP is made with propylene monomer. Polymers are macromolecules formed from a number of small molecules known as monomers.
What chemicals is HDPE resistant to?
| LDPE & HDPE resistance listed by chemical | |
|---|---|
| 1.4-dioxane | LDPE / HDPE at 20°C: little or no damage after 30 days. LDPE at 50°C: shows some effect after 7 days. |
| Hydrocyanic acid | LDPE / HDPE at 20°C-50°C: little or no damage after 30 days. |
| Hydrofluoric acid | LDPE / HDPE at 20°C-50°C: little or no damage after 30 days. |
What kind of chemical resistance does polypropylene have?
Polypropylene Chemical Resistance. Introduction. Among many of the positive attributes of polypropylene, it is probably best known for its resistance to highly aggressive chemicals. While polypropylene is highly resistant to many chemicals at room temperatures, its chemical resistance decreases with increased temperatures.
How is HMC polypropylene resistance to water?
HMC polypropylene resins have outstanding resistance to water and other inorganic environments. In most aqueous environments, its weight increase is less than 0.2% when it has been stored for 6 months at ambient temperatures. When the temperature is increased to 60°C (140°F), the weight increase is less than 0.5% for a similar period.
Are there any chemicals that are compatible with polypropylene?
What Chemicals are Compatible with Polypropylene? In general, polypropylene is chemically less resistant than polyethylene Polypropylene offers good resistance to non-oxidizing acids and bases, fats and most organic solvents At elevated temperature, polypropylene can be dissolved in nonpolar solvents such as xylene, tetralin and decalin.
How is the melting point of polypropylene determined?
Polypropylene offers good resistance to non-oxidizing acids and bases, fats and most organic solvents At elevated temperature, polypropylene can be dissolved in nonpolar solvents such as xylene, tetralin and decalin. The melting point of polypropylene is 160°C / 320°F) Low temperature threshold: polypropylene becomes brittle below 0°C
