Chemical-Resistant Slippery PTFE Powder

Color: White
Temperature Range: -300° to 500° F
For Use On: Carriages, Multipurpose, Slides, Ways, Track, O-Rings, Seals, Chutes, Guide Rails, Locks
For Use Outdoors: Yes

Often used in assemblies that rub against each other, this powder blends into plastic, rubber, composites, and lubricants to keep them from sticking. Because it is slippery, it decreases wear and dissipates heat caused by friction—it will not break down in extreme temperatures. It repels water, which keeps rust, dust, and debris from building up and causing abrasion between moving parts. This powder won’t react to most corrosive chemicals, but it will break down when exposed to alkali metal.

Diamond Lapping Grains

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains. Mix with oil, grease, or water to create your own lapping compounds. Grit and microns are approximate.

Natural diamonds are sharper and cut faster than synthetic diamonds.

Metal 3D Printer Powders

Produce complex metal parts quicker and with fewer tools and less wasted material than machining. The parts made with these powders look virtually the same as machined parts, are easy to weld, and resist corrosion. However, since they’re rapidly heated and cooled, they can form internal stresses and pores that make them more brittle than machined parts. These powders include a material certificate with a traceable lot number and test report that confirms their material composition. All were produced in facilities that meet ISO standards for quality.

Use them with powder bed fusion (PBF) printing systems, such as direct metal laser sintering (DMLS), selective laser melting (SLM), and electron beam melting (EBM). Their parts cannot be heat treated.

With added molybdenum, 316/316L stainless steel powders create parts that resist rusting and cracking from corrosion better than 718 nickel and AlSi10Mg aluminum. Choose them for parts that are often exposed to acids and chlorides in chemical, food, and marine applications.

718 nickel powders make parts that maintain their high strength even when exposed to extreme heat or cold for a long time, thanks to their added chromium, niobium, and molybdenum. Print them into parts that must stand up to harsh conditions, such as components in gas turbines and cryogenic chambers.

Blended with silicon and magnesium, AlSi10Mg aluminum powders create parts that are lightweight yet strong and hold up to repeated use. They’re often printed into parts with thin walls and components for gearboxes and brackets.

Additives and Reinforcements for Composites

Fiberglass Loose Fiber

Flake

Kevlar Loose Fiber

Mix these additives with melted plastic, epoxies, or adhesives to make parts stronger and more wear resistant without adding much weight. You can use them in batches to tackle repairs and small parts instead of machining your part from a sheet, bar, or other shape.

Fiberglass

These additives increase a part’s strength and ability to withstand frequent blows. But, they’re not as strong or as lightweight as carbon fiber additives. They also block electric currents from passing through. Their short fibers are best for castings and foams to prevent cracking as resin shrinks. The amount you use to start should equal about 10-35% of your composite’s weight.

Carbon Fiber and Recycled Carbon Fiber

Often used in vehicles to increase fuel efficiency, these additives can double your composite’s strength to make stiff pieces that are stronger and lighter in weight than aluminum. The more you add to your mixture, the stronger it becomes. These additives also carry electric currents, so they’re good for directing electromagnetic energy away from electrical devices. However, they don’t direct electricity as well as metal. They’re made of chopped fibers, which makes them ideal for repairs and intricate parts. But, they’re not as strong or as stiff as materials with continuous fibers, such as fabric and tow.

The size of carbon fiber’s particles affects its ease of use and strength. The smaller the particle size, the less effort it requires to mix. On the other hand, larger particles make parts stronger and stiffer. Choose carbon fiber with smaller particle sizes when making intricate parts and repairs.

Carbon fiber additives for thermoplastics bond with most melted plastic pellets, except PVDF. Shape your mixture into parts with compression and injection molding or 3D printing. You can shape your finished product multiple times without losing its strength. Start by adding 10% by volume to your mixture. Carbon fiber additives for thermosets mix with epoxies, adhesives, vinyl compounds, and phenolic. Use compression molding to turn your mixture into parts, or fill in cavities after curing without adding weight. You can’t shape your product once it’s cured. Begin with 5% by volume in your mixture.
