LIGHTWEIGHT INSULATIVE MORTARS & PLASTERS

Pumice is widely used as an industrial abrasive where the protection of the surface is critical. Various grades and blended grades of pumice are used to: Polish glass, clean and texturize electronic circuit boards, clean lithographic plates, prepare metal surfaces for electroplating, buff leather and fine furniture woods, act as a tumbling media for things like buttons, cutlery, small metal or plastic parts.

Pumice has a hardness in the range of 5.5 – 6 on the mohs scale which means that it can be used safely in many industrial and consumer applications where a soft abrasion is required to achieve the final sheen without causing damage to surface areas.

Pumice can be ground down to an ultrafine powder and still retain its abrasive quality due to its friability.

ELECTRONICS

Pumice powder is used in the electronic sector, particularly during the final cleansing and polishing of printed circuit boards (PCBs). 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. Scrubbing with Pumice causes minimal stress to the material and produces a favorable surface.

ABRASIVE GRINDSTONES

Pumice is used as an important constituent in many grindstones, the use of different grain sizes allows it to be applied in various industries; such as in magnesite, for MARBLE, GRANITE, and CERAMICS that are assembled in manual or automatic machines, and for pavements, where depending on the hardness of the material to be worked, an appropriate grain size with a renewable cutting surface can be applied to achieve a well-polished, finished product at a very low production cost. Pumice contributes to the high level cutting action, rendering a light, porous and automatically renewable cutting surface.

DENTISTRY

Pumice is used in dentistry during the finishing of dentures. Flour of pumice or fine pumice may be used on natural teeth and coarse pumice is usually limited to laboratory use. According to its particle size, it can be used as an abrasive or a polishing agent. clean and smooth a surface,

It is also used in oral hygiene pastes, prophy pastes, and teeth polishing compounds.

FACIAL MASKS, SCRUBS & HAND SOAPS

The use of pumice in cosmetics scrubs is well established. Pumice acts as a gentle exfoliant when used in facial masks and foot scrubs gently removing dead and rough skin leaving it fresh and revitalised. Pumice is perfect for use in industrial hand soaps to thoroughly clean industrial residue from hands. Due to the unique physical structure pumice has a smooth but energetic abrasive action.

LIGHTWEIGHT INSULATIVE MORTARS & PLASTERS

Soylu pumice comes in several grades which can be used in various formulations depending on manufacturers requirements and desired technical specifications of lightweight insulative mortars and plasters.

PUMICE IN AUTOMOTIVE INDUSTRY

Pumice is used as a filler for hot applied bituminous underflooring as a sound and heat absorbing shield. Soylu production is suitable for suppliers of sound and thermal insulation systems in motor vehicles. Pumice has been incorporated into this process due to the increasing demand for lighter items with improved features. In designing and optimizing complete acoustic systems and solutions for the automotive industry, pumice integration allows to improve the overall acoustic performance of the vehicle. Pumice utilization guarantees both thermal and acoustic protection over the entire surface area.

RUBBER

Pumice-based Erasers. The most important raw material in an eraser is rubber. The rubber may be natura lor synthetic. Natural rubber is obtained from latex produced by the rubber tree. Synthetic rubber exists in a wide variety of forms. Pumice powder is added to rubber erasers to increase abrasivity.

Mould Release Agents act as an interface between the mould surface and the material being moulded. Many speciality mould release agents incorporate a natural abrasive such as pumice into their mould release compounds.
