Do essential oils damage climbing ropes?
|
Look Luke, nylon is not degraded by gasoline, another petroleum product. It's a scientific fact. Actually read up about it instead of being a weenie. |

I have always operated with the understanding that gas is very very bad for climbing soft goods. Was told this by several climbers including an AMGA guide. what about dyneema does gas hurt it? |

I'd actualy be a bit surprised if gas managed to hurt dyneema. PP and HDPE have high resistance to gasoline and are used as portable gas containers and tanks. Dyneema is UHMWPE. However, without testing I still would not trust it. |

From the BlueWater Technical Manual: |

solid point fortuna, lets not forget there is 10% alcohol in our gas now too, could play a part? I know it is not good for a lot of the rubber components in motors. ahhhh thank you oil and gassholes for cutting my gas with something that ruins my vehicle... |

Brock B. wrote:From the BlueWater Technical Manual: Testing done indicates salt water, acetone, benzene, chloroform, freon, gasoline, kerosene, motor oil, mineral oil, paints and pine oil do not appreciably affect nylon and should not damage your rope.Yea well that's Bluewater ropes! How do I know gasoline and scented candles won't damage my Sterling rope :) |

Gasoline doesn't damage aluminum. If took online classes instead of trolling MP you would know that |

Was told this by several climbers including an AMGA guide. But the fact remains that both you and the AMGA guides you spoke to are misinformed. And, probably have less of a chemistry background than most people, so really, it's nothing to be ashamed of. I only learned this in the past ten years. Gas is bad for us to ingest, but nylon can resist gasoline, kerosene, etc. quite nicely. It resists other nasty shit as well, which is why many chemicals are stored in plastic containers of a similar structure to nylon. Start here: calpaclab.com/nylon-chemica… Gasoline (high-aromatic) A-Excellent Gasoline, leaded, ref. A2-Excellent Also important. Nylon can be exposed to beer: Beer A1-Excellent en.wikipedia.org/wiki/Nylon_66 From Valley Industries industrial site: "Nylon is resistant to a broad range of chemicals including most agricultural chemicals, ammonium compounds, detergents, diesel fuel, ethanol, gasoline, hexane, magnesium sulphate, most sodium compounds, trichloroethylene and zinc sulphate." Fuel Resistant Plastics: polymerplace.com/articles/a… And that's just what I found in a five minute search. There are of course other threads where this has been discussed ad nauseum (Supertopo, here, rockclimbing.com no doubt) but trust me. I wouldn't make this up or share nonsense.

I'd like to point out that we're interested in a particular property of specially produced nylon. Its elasticity and tensile strength. Even if there is little degredation of other physical properties of nylon we don't know if it retains its full rated strength and dynamic elongation. Soak some rope in gas and do some UIAA fall testing on it. |

Dunno. I bet it ain't good for the belayer 's hands, though. |

LOL, went from me asking about essential oils affected climbing ropes to gasoline to diarrhea. How things get off topic LOL its funny to read :P |

Soak some rope in gas and do some UIAA fall testing on it.May I direct your attention upthread just a bit. BlueWater seems to have done the testing. They are quite clear: gasoline doesn't harm ropes. It's not surprising. Gasoline is known to have no adverse effect on Nylon. Everyone but a few newbie climbers seem to understand this. All the general compatibility publications e.g. Cole-Parmer communicate this reality. Despite Luke's extremely superficial rule-of-thumb, Nylon is not soluble in hydrocarbons for the simple enough reason that it is not a hydrocarbon. It is a polyamide polymer. Automotive fuel system components, like the disposable translucent fuel filter that used to be common on Japanese subcompacts 20 years ago, are made of Nylon. But, whatever. Luke, if you're reading this and you ever get your rope splashed with a little stove fuel, let me know. I'll wager you a new rope that I can whip on the contaminated cord and not die. |

Some essential oils have to be stored in glass. They are corrosive and will eat plastic containers. Wear long sleeves |

It's a government mandate and they fought it for years. Think about it: with the stroke of the legislative (regulatory actually, but let's not split hairs) pen, the Oil Cos. lost 10% of their product volume. |
