STAR Pumice Powder is used in both cartridge and open multi-media filters. In cartridge filters, STAR Pumice Powder can replace sand, zeolites, and carbon based filter media. The narrow particle size range and rough surface texture of STAR Pumice Powder provide an open void volume, which increases flow rates while maintaining excellent adsorption and impurity trapping capabilities.

In multi-media filters, STAR Pumice Powder, effectively replaces anthracite coal on top of the sand layer.STAR Pumice Powder, like anthracite, has a low density, which facilitates trapping the impurity particles in the open void volume of the larger pumice particles thus preventing the blinding of the top of the sand filter media. This leads to longer run times and reduced back-washing.

In addition to its standard products,STAR Pumice Powder  can provide custom grades as requested. All STAR Pumice Powder  products

Printed circuit board manufacturing is a complex industry requiring numerous processing steps to produce single or multi-layer printed circuit boards.

The unique abrasive/polishing characteristics of STAR Pumice Powder can be used during printed circuit board manufacturing.

Brush scrubbing with pumice has been the industry standard for many years. 
The use of nylon brushes with a suspension of pumice in water results in excellent surface topography. STAR Pumice Powder, with its narrow particle size and Mohs hardness of 5.5 to 6.0, provides uniform abrasion/polishing.

During the panel preparation step, the panels are subjected to anti-oxidant baths, cleaners, and pumice scrubs similar to the core preparation.

Mechanical scrubbing methods include abrasive brush scrubbing and pumice scrubbing. Brush scrubbing removes a thin layer of surface copper, thus ensuring a clean surface, but tends to impart stress to a thin core material by deforming it during the scrub. Brush scrubbing can also produce a surface not compatible with fine-line circuit designs.

Scrubbing with STAR Pumice Powder imparts less or no stress to the material and produces a favorable surface.

Chinchilla and other small furry animals should not be bathed in soap and water. Instead, their fur should be cleaned in a manner consistent with their natural instincts, which is to take a dust bath that absorbs the oils and dirt attached to their fur. 
Fine particles of pumice provide an excellent dust bath. The animal rolls around in the pumice dust, and the pumice attaches to the fur, absorbing oil and dirt. The dust then falls off the fur during normal activity.

STAR Pumice Powder is employed in many seed coating applications, and provides several benefits.

Coating plant seeds prior to planting is a common practice in modern agriculture. 
Seed is coated when growers need a precision-sown crop and the non-coated ("raw") seed is too small, too light, or too variable in size or shape to be sown accurately with existing equipment. The objective of coating is to deliver the seed in a form that is larger, rounder, smoother, heavier and more uniform than the original seed. 
Precision sowing is desirable when growers need singulation, e.g., for cell-tray plant production in a greenhouse or strict control of spacing or depth of placement. 
For example, onion spacing is critical to achieve desired bulb size at harvest. Singulation and controlled spacing are also vital for crops that are direct sown and then thinned back to the desired population. The field thinning operation is faster, cheaper and more accurate when coated seeds are used. A further advantage to coating seeds is the additional weight the coating adds to each seed. The additional weight renders the seeds more resistant to water and wind erosion.

As crop protection, seed coatings can also be a carrier of fungicides, bactericides, 
and insecticides that protect the seed and emerging seedling. Seed coating offers many benefits in comparison to traditional methods that require the use of expensive and complex chemical application equipment. Seed coatings also may consist of polymer coatings to delay germination, pH modifiers and various nutrients. Additionally, coatings can contain a coloring agent which provides visibility during seed placement, identification of grade or variety as well as differentiation between sellers. Because of its high level of porosity, pumice serves as an excellent chemical carrier in seed coating.

Seed coating relies on technology developed by the pharmaceutical industry to make medicinal pills. Commercial seed coating operations put seed in a rotating pan, mist with water or other liquid, and gradually add a fine inert powder such as pumice to the coating pan. Each misted seed becomes the center of an agglomeration of powder that gradually increases in size. The pills are rounded and smoothed by the tumbling action in the pan, similar to pebbles on the beach. The coating powder is compacted compression from the weight of material in the pan.

Binders such as polymers and hemicelluloses often are incorporated near the end of the coating process to harden the outer layer of the pill. Binders can also reduce the amount of dust produced by the finished product in handling, shipping and sowing.

Pumice is often used as an excipient, providing body, viscosity and coating integrity to complex seed coating formulations.

Seed coatings produced with an inert powder such as pumice can be of two types:

  • They can absorb water, transfer this water to the seed, and split exposing the germinating seed (“split coats”).
  • The seed coating can dissolve when wet and gradually wash away from the seed freeing the seed (“melt coats”).

Split coats initially retain their shape when wet and, by capillary action, pass moisture through the pill to be imbibed by the seed. The seed swells and cracks the pill by internal turgor pressure. The split coat often permits germination with less water, as the coating splits, allows uniform, rapid oxygen access to the surface of the seed. The moisture retention properties of pumice make it an excellent inert powder in split coat applications.

The melt coats dissolve when wet and gradually wash away from around the seed. The melt coats often require more water to wash the coating material away from the seed, and more time for the oxygen to reach the seed through the saturated coating material. The porosity of pumice allows it to both release water and oxygen to assist in germination of melt coated seeds.

In the United States, the major high-volume vegetable crop being using seed coatings is lettuce. Carrot, celery, endive, escarole, onion, pepper, and tomato also are coated to a significant extent. Begonia is the flower crop most frequently sown in coated form. Impatiens, marigolds and petunias are also coated commercially and the market for coating these and other species is growing. Alfalfa and tobacco are two agronomic crops that are coated.

Pumice can be used as a seed coating to protect against insects. The pumice coating prevents insect damage and will eventually desiccate any insects.

STAR Pumice Powder is a preferred by many seed coaters because it is all natural and contains no artificial ingredients or chemical additives. This allows STAR Pumice Powder to be used in organic cultivation. Many seed coaters also prefer STAR Pumice Powder to other inert powders such as calcined diatomaceous earth because of its lower crystalline silica content and because it contains no deleterious clay.

Rubber Pumice Abrasive Wheels are excellent for many cleaning, polishing, and finishing needs. They are made from natural rubber with imbedded pumice grains that are evenly distributed to assure uniform results. The light abrasive action produces a smooth finish on soft metals.

Pumice-Based Erasers are the standard for almost every office/school grade pencil. They will erase the toughest graphite markings, and they are particularly effective on hard papers, such as photocopy paper.

Mold Release Agents act as an interface between the mold surface and the material being molded. Many specialty mold release agents incorporate a natural abrasive such as pumice into their mold release compounds.
