What is p-tex base material?
Many skiers erroneously refer to the base material as P-Tex—a brand name for the polyethylene created by the European company International Mountain Sport. In fact all base materials are Ultra High Molecular Weight polyethylene (UHMW)—a close cousin of the opaque milk jug—and made from number two High Density Poly Ethylene (HDPE).
What is Gore-Tex made of?
Gore-Tex is a membrane made from a stretched polymer that has over 9 million pores per square inch. These pores are small enough that water droplets cannot fit through but large enough that condensation inside can evaporate.
What do the different colors of PEX pipe mean?
Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold. Red PEX pipe carries hot water. Blue PEX pipe carries cold water.
When did PEX become used for water supply systems?
While PEX use for water supply systems has been widespread in Europe since the 1980s, it was a latecomer here because some early versions deteriorated slightly when exposed to the high chlorine levels common in US water supplies.
What is ski PTEX made of?
Sintered p-tex is made by packing ultra high molecular weight polyethylene powder into a cake that is heated and compressed (sintered) to form a log or billet (see diagram below). A lathe or mill is then used to shave (scive) off a thin layer to the desired thickness.

Does PTEX absorb wax?
Often referred to by the trade name p-tex, it's a strong and impact-resistant substance with a low friction coefficient. Because p-tex is porous, almost like a sponge, it can absorb wax time and time again.
What can you use instead of PTEX?
I use a combination of a razor, file, and metal scraper. You can also run it over a grinder at your shop, I'm sure they will do it for free. Wax your skis and be on your way.
Can you use a hot glue gun for PTEX?
No a hot glue gun will not work.
Is PTEX toxic?
If you're holding it high enough to actually drip, that's bad, you'll see the drips light up with the yellow flame as they fall, not good. You can also try texturing the inside of the gouge with a file first, this can help the p-tex stick better. Also work somewhere well ventilated because the p-tex smoke is toxic.

If you look closely at picture, you can see the cutout outline and 2 horizontal lines where the edge peak is.
How to dripping P-Tex?
Before starting the process of dripping p-tex, remove any flammable cleaners from the work area to a safe place. Sharpen the end of the p-tex candle so it will light easier. Light one end of a P-Tex candle with a match/torch; hold the candle above the flame. CAUTION!
What to do if P-tex burns?
If the p-tex continues to burn on the base, blow the flame out so the base does not overheat. Deeper gouges should be filled in multiple passes, allowing each layer to cool before adding the next. Any repairs on damage near the edge or very deep should begin with metal grip and a soldering iron (see video below).
How to repair a carbon base?
To repair base bubbles (from overheating a base): Either 1) First, drill a small hole or make a small slit with a razor knife through the p-tex in the center of the bubble.
How to prevent carbon buildup in p-tex?
Structure if needed with a coarse metal brush and gray pad. To prevent carbon formation when using p-tex: The key is to maintain a blue flame (don't let it burn orange). To do this, keep it low to the base or close to a metal scraper. This will minimize carbon buildup.
Can P-TeX candles withstand snow?
Keep in mind that p-tex candles are too soft to withstand snow abrasion and will wear out; you may wish to consider a professional repair job. Slightly overfill the gouges. After repairs have cooled, remove excess material by planing it off with a metal scraper.
What is Gore-Tex?
Gore-Tex is a breathable, waterproof membrane that keeps you dry from the outside and from the inside. We will get into the technical details shortly, but for now, think of it as an advanced fabric layer that is glued between the lining and the outer of a waterproof garment.
What is Gore-Tex Made of?
Gore-Tex is made from a stretched polymer. Well, what is a polymer, you might be wondering? Synthetic Polymers like polypropylene and PTFE’s are thermoplastics which means they soften when heated and all have similar chemical properties.
How is Gore-Tex Made?
But what about specific Gore-Tex fabric? How is that polymer turned into the waterproof and windproof jackets and pants we wear on the mountain? Gore-Tex fabric tends to come in three main styles, 2-layer, 3 layers, and Z-layer that all have different compositions and are made in slightly different ways.
How Does Gore-Tex Work?
Gore-Tex is a membrane that has more than 9 million tiny pores in a square inch. These perforations are almost 2000 times smaller than your average water droplet molecule, but 700 times larger than those of water vapor.
How long does it take for UHMWPE to cool down?
When UHMWPE is annealed, the material is heated to between 135 °C and 138 °C in an oven or a liquid bath of silicone oil or glycerine. The material is then cooled down at a rate of 5 °C/h to 65 °C or less. Finally, the material is wrapped in an insulating blanket for 24 hours to bring to room temperature.
What temperature does UHMWPE melt?
Its melting point is around 130 to 136 °C (266 to 277 °F), and, according to DSM, it is not advisable to use UHMWPE fibres at temperatures exceeding 80 to 100 °C (176 to 212 °F) for long periods of time. It becomes brittle at temperatures below −150 °C (−240 °F).
Why does UHMWPE feel slippery?
For the same reasons, skin does not interact with it strongly, making the UHMWPE fiber surface feel slippery. In a similar manner, aromatic polymers are often susceptible to aromatic solvents due to aromatic stacking interactions, an effect aliphatic polymers like UHMWPE are immune to.
What is UHMWPE made of?
UHMWPE is a type of polyolefin. It is made up of extremely long chains of polyethylene, which all align in the same direction. It derives its strength largely from the length of each individual molecule (chain). Van der Waals bonds between the molecules are relatively weak for each atom of overlap between the molecules, but because the molecules are very long, large overlaps can exist, adding up to the ability to carry larger shear forces from molecule to molecule. Each chain is bonded to the others with so many van der Waals bonds that the whole of the inter-molecular strength is high. In this way, large tensile loads are not limited as much by the comparative weakness of each van der Waals bond.
How many monomers are in HDPE?
These molecules are several orders of magnitude longer than those of familiar high-density polyethylene (HDPE) due to a synthesis process based on metallocene catalysts, resulting in UHMWPE molecules typically having 100,000 to 250,000 monomer units per molecule each compared to HDPE's 700 to 1,800 monomers.
What is Spectra used for?
In these blends, the UHMWPE fibers are blended with, for example, Vectran . In skydiving, Spectra is one of the most common materials used for suspension lines, largely supplanting the earlier-used Dacron, being lighter and less bulky.
What is fluoropolymer cable?
Fluoropolymer / HMWPE insulation cathodic protection cable is typically made with dual insulation. It features a primary layer of a fluoropolymer such as ECTFE which is chemically resistant to chlorine, sulphuric acid and hydrochloric acid. Following the primary layer is an HMWPE insulation layer, which provides pliable strength and allows considerable abuse during installation. The HMWPE jacketing provides mechanical protection as well.
What type of fittings are used for PEX?

What color is PEX?
Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
What type of PEX pipe is used for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
What is PEX pipe?
Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects. You’ve probably seen rolls of blue and red PEX pipe in the plumbing aisle of your local home improvement store, but might not know that this colorful tubing now makes it possible for enthusiastic DIYers to replace their own leaky water lines instead of calling a pro. Read on to learn more about PEX—what it is, where it can be used, and all the pros and cons of this popular plumbing material.
