Calcium Oxide Powder

Calcium Oxide Powder
Ask For Price
Our calcium oxides are powerful desiccants that can alleviate problems which develop during the processing of elastomeric and thermoplastic compounds due to the presence of moisture.

Moisture can be present in raw materials e.g. polymers (especially hydroscopic types such as ABS, polyamides etc.), fillers and plasticizers. As little as 0.2% moisture can cause porosity in the end product if it is allowed to expand freely into water vapor at polymer processing temperatures.

Whilst pre-drying raw materials can help, this is often an expensive and time consuming process, and the use of vented processing does not always solve the problem entirely.

Mode of Action :
Calcium oxide reacts exothermically with water, converting to calcium hydroxide. The decomposition temperature of calcium hydroxide is approximately 500°C, well above the typical processing and service temperatures of plastics and rubbers. The calcium hydroxide formed, will act as an inert filler in the end product

Our Calcium Oxide powder grades are available from 300 Mesh particle size to Micronised grades like 15 microns. We have one of the best raw material of Calcium oxide in India. This product is also known as Anti Moisture powder or Moisture remover powder in Local Indian Market.

Packing :
Ashirwad calcium oxide grades are available in 25kg poly-lined bags and pre-weighed sachets of 1 kg.

Application :

PVC Plastisols :
Calcium Oxide Powder Both plasticiser and fillers can contribute to unacceptable moisture levels in plastisol which can lead to a variety of problems in automotive underseals, sealants and mastics, sound deadening compounds, fabric coating, carpet backing and foamed products.

The use of Ashirwad calcium oxide prevents corrosion of plastisol-coated metal parts, improves adhesion to metal and other substrates in foamed products.

Use in Polyolefin Compounds :
Most fillers within Polyolefin compounds contains some moisture and this can cause porosity in compounds where there are high filler levels present (>25%). The use of Ashirwad calcium oxide reduces porosity by the reaction with any moisture present.

Use in Hydroscopic Polymers :
Polyimides and ABS are inherently hydroscopic and the moisture absorbed can lead to surface defects such as "silver streaking" in molded products. To avoid prolonged oven drying, particularly for polyimides where the polymer/water bond is particularly strong,
Our calcium oxide is invaluable to remove any moisture absorbed.

Use in Polymer Recycling :
Reclaimed thermoplastics have often been stored in damp conditions and can contain significant amounts moisture. Oven drying requires capital expenditure, high energy inputs, and extra labor costs. These high potential costs can be reduced by using Our calcium oxide in the recycling process and removing moisture from the polymers the be recycled.

Packing :
Ashirwad calcium oxide grades are available in 25kg poly-lined bags and pre-weighed sachets of 1 kg.
