Until the mid-1980s, most ski waxes were relatively simple compounds called hydrocarbons, containing exclusively hydrogen and carbon. They effectively reduce (dry friction) but are only fair, or even poor solutions to other (friction) components. Most hydrocarbons are derived from crude oil ?E"natural waxes" ?E or coal ?E"synthetic waxes ?Eand are available in a variety of hardness grades.

A hydrocarbon is any organic compound composed solely of carbon and hydrogen. Hydrocarbons include aliphatic compounds, in which the carbon atoms form a chain, and aromatic compounds, in which the carbon atoms form stable rings. The aliphatic group is divided into alkanes (e.g., methane and propane), alkenes, and alkynes (e.g.
Hydrocarbon molecules that cluster and grow causing molecules to be trapped from air during the combustion process.

Good hot waxes melt just above body temperature so they can be easily spread thinly over the skin. As they harden they trap the hair in the wax so it is removed by the roots when the wax is ripped off. Cold waxes are available in pre-coated strips which can be pressed directly onto the skin. The hair sticks to the wax and is then removed with the quick pull back action.
Introduced in the mid-1980s, fluorocarbon waxes (more correctly called perfluorocarbons) are synthetic products containing exclusively fluorine and carbon. Applied over base waxes, they offer outstanding performance on wet and relatively new snows; they resist oil and dirt, and reduce (wet friction) and (friction from dirt). On the downside, they lack mechanical strength, are easily penetrated by aggressive snow crystals, and tend to "stick" at snow temperatures below -10C (14F).
Fluorinated paraffins -- or fluoros -- became available around 1990. Fluoros can be blended with warm or cold (hydrocarbon waxes) to produce fluorinated waxes in a variety of hardness grades. These waxes reduce wet friction and friction from dirt. A minimum amount of fluoro (2-3%) produces noticeable effects and more (3-15% depending on humidity) provides optimum results. Fluorinated waxes include DOMINATOR's FX series, HyperZoom, RaceZoom, Rocket, and Nordic Gliders.
Despite the antistatic claims of some companies, only graphites address friction from static. Graphite waxes are created by adding graphite, a black powder with antistatic and lubricating properties, to hydrocarbon or fluorinated waxes. Typically, the ratio of graphite to wax is approximately 1 to 99. The grade of graphite is critical; the smallest possible particle size must be used so it does not interfere with the base structure.
Waxes are used more by overland touring skiers than by downhill skiers because waxes are most effective for shorter climbs where the hill is not very steep. When the work well, waxes are much more convenient than skins. This includes using wax for mountain skiing too.
New Energy FAQ
In the New Energy Age, there will still be a market for hydrocarbon substances (oil, natural gas, even coal), at least for a time. These will be used in the chemical industries to make plastics and in many other industrial processes in which these substances have value as feedstocks.
Floor Sanding FAQs
Varnish coats the top surface of the floor, and forms a hard surface when it dries. This is the usual way of finishing wood floors. Oil is sometimes used on hardwoods i.e. oak, walnut, tropical hardwoods etc. It works by being absorbed into the timber and relies on the natural inherent strength of the timber itself to protect its surface. If oil is being used, the floor should be fine-finished in preparation.
Billanti Casting Co., Inc. - FAQ's
Your waxes and originals are very fragile and delicate pieces. Please take great care in packing them; the parcels are often abused in shipping and they can break easily. Use plenty of absorbent packing material around each individual piece, preventing them from movement, and use a large sturdy box. Of course, always include a list indicating the number of pieces enclosed so that we'll know if something arrives broken.
Although a variety of low-cost fluorinated additives, the products wax manufacturers blend with (hydrocarbon waxes) to create (fluorinated waxes), is available, only those developed specifically for waxes are suitable. Some commercial fluoro waxes contain a low-cost ultra-fine fluoro powder -- PTFE, commonly known as Teflon -- whose effectiveness as a wax additive is highly questionable. Some other brands contain 0.

Some fragrance raw materials, inherently, have color. These, fragrances that inherently have color can discolor paraffin. In such case, it is important to work with your dye manufacturer so they incorporate the fragrance's natural color when formulating the dye you will be using.
FREQUENTLY ASKED QUESTIONS: Meguiar's Marine/RV
Meguiar's Marine/RV products are specially formulated for gel coat and linear polyurethane (LP) surfaces, which are chemically different than automotive paints. Modern gel coats and LP coatings are harder and more water resistant than automotive paints. Their unique chemical compositions demand special ingredients that are specific to these marine uses and formulated for use in marine environments. Automotive products will not achieve the same high quality results on boats or RVs.

No. All types of candle waxes perform well, and will burn cleanly and safely when they are of high quality. U.S. candle manufacturers select waxes or blends of waxes based on their suitability for specific types of candles or formulation profiles, as well as their own candle-making preferences.
Perma Sheild Products
THE PERMA SHIELD SYSTEM will outlast wax about 6 to 1, saving you much time & effort! It is also much less effort in application and removal, with no hard buffing required! Unlike waxes, PERMA SHIELD doesn't build up in cracks and become an unsightly mess.
Coolman Corporation Co., Ltd.
Yes. The Cold™ Hydrocarbon Refrigerants line of products is NON-OZONE DEPLETING and NON-GLOBAL WARMING. Only hydrocarbon refrigerants can claim to achieve both of these criteria. GREENPEACE have been long singing the praises of the hydrocarbon techn The propane that is regularly used for barbecues, and general consumer or commercial use is a by product or deritive of the hydrocarbon manufacturing process (the production and refining of raw oil products).
