Vimcro Talc is a metamorphic hydrated magnesium silicate with a soapy feel and pearly luster. Its lameller structure and the platyness give excellent opacity to the end products.
Distinct Features:
Composites filled with VIMCRO TALC enhance the performance properties of the compound. It exhibits higher stiffness, creep resistance at both ambient and elevated temperature.
Advantages for Polymer:
* Good surface quality
* Lower mould shrinkage
* Easier processing
* Better transperancy.
Applications:
* PP compounds used in automotive and appliances
* Ps compounds
* Additive masterbatches for paper like LLDPE & HM, HDPE films
* Additive masterbatches for PP & HDPE box strapping.
Calcite is a natural form of calcium carbonate widely used in plastics, paints and rubber as a filler due to its high dispersibility, low oil absorption, higher impact strength, smooth surface finish, easy processing and excellent dimensional stability.
Vimcro Carb is available in controlled particle size to give better results to the end products.
Effects on properties of polymers:
* Increase in flexural modulus
* Increase in dimensional stability
* Reduces Creeping
* Increase in HDT
* Lower melt viscosity
* Improved electrical properties
* Improved processing characteristics
* Good dispersion.
Recommended Application:
* PP compounding for furniture, automobiles and home appliances
* Antifabrilliant Masterbatches for PP and HDPE woven sack
* Colour Masterbatches and other Additive Masterbatches
* PVC Cable compounding
* Paints
* Paper Coatings
* Thermoset plastic - SMC, DMC, RTM, Pultrussion
* Vinyl floorings
* PU foam (Flexible and Rigid).
Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite. To be classified as a quartzite by the British Geological Survey, a metamorphic rock must contain at least 80% quartz by volume

Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods
