high quality and low price cenospheres for oil wells drilling

 TONTEN ^R cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their density is about 0.4–0.8 g/cm3 (0.014–0.029 lb/cu in), which gives them a great buoyancy.

Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers. Cenospheres are now used as fillers in cement to produce low-density concrete. Recently, some manufacturers have begun filling metals and polymers with cenospheres to make lightweight composite materials with higher strength than other types of foam materials. Such composite materials are called syntactic foam. Aluminum-based syntactic foams are finding applications in the automotive sector.
Silver-coated cenospheres are used in conductive coatings, tiles and fabrics. Another use is in conductive paints for antistatic coatings and electromagnetic shielding.

1. Refractory: Ceramic Hollow Microspheres can be as raw material for thermal insulation refractory products.
2. Construction: Ceramic Hollow Microspheres can be made of roof waterproof insulation coating, road works, modified asphalt 

    etc.
3. Plastics: Polyethylene, polypropylene, nylon, PVC, compounding, film, urethane, potting compounds.
4. Painting & Coating: Ceramic Hollow Microspheress are special additives in the paints and coatings industry due to the lowest 

    surface area. Ceramic Hollow Microspheres can reduce resin demand and increase volume loading capacity.

5. Ceramic Hollow Microspheress can be used in Oil field.
6. Ceramic Hollow Microspheress also can be used for insulant.
