Product Description

Iron-free grinding of selected quartz sand with a high SiO2-content in ball or vibration mills produces silica. The controlled particle size distribution is realized using rotor driven air separators.
It is used as cheap filler in plaster and some plastics to add strength, or just to reduce the amount of (expensive) resin needed to fill a mold.
For polymer systems, silica fillers are mainly used for property enhancements. The major improvements imparted by silica include increases in stiffness, strength, temperature resistance, dimensional stability, surface hardness and scratch resistance. These properties are in ever-increasing demand, as the surface requirements for plastics are growing too stringent for unfilled polymers.
FILLERS:
Low oil absorption, high mechanical strength, chemical inertness and ideal optical characteristics are strong assets for quartz:
  • Floor paints are resistant to wear and tear as a result of the hardness of quartz fillers
  • Transparent silica fillers enable durable wood protection and also allow the decorative structure of the wood to remain visible
PLASTICS:
  • In various polymer applications (PU, Epoxy, PET, PP) micronized quartz provides exceptional benefits. The cycle time reduction in die-casting is a result of the exceptionally high thermal conductivity. The durable optic matting of the surface gives synthetic grass and textile fibers a more natural look.
CHEMISTRY:
  • Silica is an excellent raw material for chemical products and is applicable in acid reactors through inertia, e.g. in the production of titan dioxide.
ADVANTAGES
  • Some of the potential advantages that can be gained are weather and chemical resistance, reduced raw material costs, reduced flammability, water resistance, better thermal conductivity, enhanced electrical properties and improved whiteness.

The introduction of finer particle size silica fillers gives improvements in strength and stiffness, as well as enhancing surface smoothness and gloss. There is also the benefit of reduced wear on contact parts during processing. It should be considered that due to the higher surface area of these products, viscosity will increase and filler loading will not be as high. Potentially this can be addressed by the use of a surface modified product.

    About the Company

    Year of Establishment1998
    Legal Status of FirmPrivate Limited Company
    Nature of BusinessManufacturer
    IndiaMART Member SinceDec 2011

    Minflex Polymers was established in 1998 with the aim and a determined effort to get into plastics and rubber industry.

    Minflex was a second venture of its proprietor first being, Rajasthan Metamin Fertichem Ind. (RMFI), was established in 1974 and since then the company is dealing in Talc, soap stone, calcium carbonate and other minerals with our clients across the globe for the excellent quality and outstanding customer services that we provide.

    Our successful entry and retention in the plastic and rubber industry happened only because we have team of plastic professionals, who are technically qualified and have rich knowledge of their specific domains like injection molding, film extrusion, pipe and profile extrusion, rubber compounding etc., who in turn help us attain maximum customer satisfaction.

    The success of our additives and products can be evaluated just with a fact that in an international exhibition alone we got more than 400 enquires for our product. We have a very strong customer network covering almost 10 states in India and approx 5 countries throughout the world.

    We are always looking to represent global manufacturers of quality products so as to offer our customers even a wider range of additives and products.
