Flame Retardants
We are known name in manufacturing expandable graphite based flame retardant additives to various industries. Our products comprise Anti-dripping property which prevents base material from dripping during burning. These additives are single Non-Halogenated, non toxic, Eco-Friendly and Cost-effective Flame Retardant additive. The provided grades are used to manufacture Flame Retardant products such as Mattress, Seat Cushion, Seats for Buses, Trucks, Car, Train, Aeroplane and many more applications. We supply customized product grades as per customer requirement. These additives have shelf life more than the base material, so that these additives do not get deteriorated. We are offering the following products:

Covering Compounds Additives The insulating compounds are actually used for covering the casting risers to confine shrinkage cavities to safe level in riser. The hot topping compounds is added on the surface of liquid metal and then it burns immediately. Later on it forms an insulating and porous crust and therefore heat loss due to radiation is minimized. The powder spreads evenly on the liquid surface. The crust so formed is powdery in nature and the fumes are very low. It requires less powder as it has good expanding properties. This actually helps to maintain the metal in liquid state for longer time so that feeding to the casting is more efficient.
The temperature required for liquid steel in the riser is maintained very well. The rate of cooling of liquid metal in the riser is longer due to high insulation properties of the insulating compounds. In precise, the insulating compounds keep metal more hot in riser area for a long time for efficient feeding so as to eliminate casting rejection due to shrinkage, porosity, piping etc. and casting produced are sound and pressure tight. Following are its advantages:
Advantages :
- Easy in addition.
- Efficient feeding.
- Insulating Compounds do not introduce any impurities in the riser metal.
- Riser heads can be easily and safely remelted.
- Rejection due to shrinkage cavities totally avoided.
- Cost effective
- No obnoxious fumes
