Uncoated Calcite (Vimcro Carb)
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).
Vimcro Barytes is a natural Barium Sulphate having high whiteness. It is also characterised by very high bulk density and inertness to both acids as well as alkalies. Vimcro Barytes is totally insoluble in water.
Vimcro Barytes finds extensive application as an extender due to its high Refractive Index, low Oil absorption, low abrasiveness, easy dispersion and higher temperature stability.
Distinct Features:
* Very low oil absorption
* Excellent compatibility with coloured pigments
* Very high dispersibility
* Good filling Capacity
* High Gloss in Enamel applications
* Imparts impermeability and durability.
Applications:
* Polymers
* Paints
* Drilling Mud
* Construction Chemicals
* Rubbers
* Papers
* Glass.
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.
