Is nitrile compatible with methanol?

HNBR (Hydrogenated Nitrile) HNBR experiences some effects from methanol exposure with some loss of physical properties and some swelling. Performance in methanol exposure is similar to that of NBR.

Is methanol compatible with carbon steel?

Copper and Copper Alloys Copper and copper alloy plating and cladding over carbon steel is aggressively attacked and is not recommended for methanol service.

Is PTFE compatible with ethanol?

Teflon® (PTFE) is one of the most chemically resistant plastics and has excellent chemical compatibility with 200 proof ethanol.

Is silicone compatible with methanol?

Silicone/Fluorosilicone Both silicone and fluorosilicone polymers show very good resistance to methanol exposure. These polymers will give the broadest temperature range, but they are not recommended for some dynamic applications due to poor tear strength and low abrasion resistance.

Is methanol corrosive to rubber?

But methanol can have problematic effects on rubber seals such as o-rings, causing rubber swell in methanol-producing equipment as well as in seals where methanol is used as an additive.

Does methanol react with stainless steel?

with small diameter openings are extremely susceptible to corrosion from many reversed- phase blends. Both acetonitrile and methanol solutions reacted with 316 stainless steel surfaces, often resulting in component failure within 24 to 48 hr.

Does methanol eat stainless steel?

Over the course of a one-month immersion in pure methanol, a stainless steel sintered disc contaminates the methanol with about 80 ppb of iron, 3 ppb of chromium, and 10 ppb of nickel. These values are only semi-quantitative as sample preparation may lead to minor contaminations.

Does ethanol react with polypropylene?

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.

Is PTFE chemical resistant?

The chemical resistance of Virgin PTFE is excellent. It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine and other extremely potent oxidisers.

Does methanol degrade silicone?

Silicone/Fluorosilicone Both silicone and fluorosilicone polymers show very good resistance to methanol exposure.
