Manufactured to our own formulated specifications, containing only the finest raw materials available. Plastic tumbling media is used with finishing equipment for surface preparation and improvement on most metals, such as aluminum, brass, copper, and zinc, as well as plastic. Plastic media will reduce distortion, impingement, and burr roll-over while producing excellent finishes prior to plating and or painting. Fine finishes and aggressive cutting can be achieved.

Low Density Preformed Media

Low density media is used within the metal industry for surface preparation and improvement on most metals such as aluminum, brass, copper, and zinc as well as plastic. Low density media will reduce distortion, impingement and burr roll-over while producing excellent finishes prior to plating and or painting. Fine finishes as well as aggressive cutting can be achieved.

R-1250A fast-cutting plastic tumbler media composed of a blend of coarser abrasives. To be used for rapid cut-down when aluminum oxide impregnation cannot be tolerated and a fine surface finish is not required. Weighs approximately 70 lbs. per cubic foot. Color is black. PH7

High Density Preformed Media

A completely NEW AND IMPROVED line of fast cutting polyester media, designed and formulated to provide a wider range of surface finishes. It contains agents that improve overall performance considerably which are technically superior to resin bonded media and urea formaldehyde media. Our new and improved media also has an average bulk density of 100lbs per cubic foot. This represents over 35% higher density than standard plastic media and 20% higher density than most ceramic media. It has been designed to reduce standard plastic media process time by 50% while improving surface finish, without additional cost. It will also cut as fast as most ceramic media but will produce a superior surface finish without hardening the metal surface. When used with proper water and compound flow rate, our new media reduces foaming and allows faster settlement of solids. It will produce a clean, surface finish on ferrous, non-ferrous, or plastic components. It will not fragment and is currently available in more than thirty shapes and sizes.

CompositionDescription
R1000-HDPLASTIC- CERAMIC HYBRID MEDIA, a completely NEW AND IMPROVED line of fast cutting polyester media, designed and formulated to provide a wider range of surface finishes. With the force and weight similar to ceramic media yet the non-impinging value of plastic media. Formulated with zircon abrasives for fine finishing of all ferrous, non-ferrous, and plastic components. Weighs approximately 95lbs per cubic foot. The color is tan
R-2000-HDDesigned as an extremely fast cutting media suitable for all materials. It produces low R.M.S. surface and superior pre-plate finishes. It contains no aluminum oxide and should be used when the wear rate is not a prime factor. Weighs approximately 100lbs per cubic foot. The color is gray. PH7
R-3000-HDDesigned for use on components such as stainless steel, forgings, and titanium. It is also suitable for use on most base metals, plastics, and produces a very low R.M.S. finish. Weighs approximately 100lbs per cubic foot. The color is Blue. PH7
R-4000-HDDesignated for low Ra finishing, especially aerospace turbine and compressor blades. This media is very clean in process and can be used on all metals and plastic components. Weighs approximately 95lbs per cubic foot. The color is Ivory. PH7

Synthetic Preformed Media

Synthetic Media is a blend of urea formaldehyde resin and abrasives. It is acidic with a PH3. If running non-ferrous metals, correct compounding is required to eliminate corrosion. Very clean non-foaming, non-surface residue. Good for pre-plate finish and a very low Ra surface can be obtained. Recommended for high energy processing and finishing delicate parts.

Note: Keep from freezing

CompositionDescription
