Leading Supplier of Silicone Antifoam

Mera Chemicals is one of the leading suppliers of silicone antifoam solutions for a wide range of Australian businesses. Our silicone antifoam product is made right here in Australia.

Silicone antifoam is a preventative product and is added to the process to prevent foam occurring and knocks down foam from building up. In layman’s terms, it is a chemical product that is essential in solving the problem caused by foam.It destabilizes tiny foam bubbles by weakening the wall that supports them. The antifoam makes the small bubbles join up to become bigger foam bubbles which burst over time and disperse.

Silicone Antifoam can be used in food processing or drink manufacture and a wide range of industries such as chemical processing, paper production, fermentation, solvent production, textile manufacture, and waste treatment.

The chemical magic of our Australian Made silicone antifoam product means that for a small additional cost, in so many industries, applications and processes, not much works without it!

If you have a foaming problem in your business, we can help. Get in touch and we can provide a sample silicone antifoam product or help you with a bespoke solution. Don’t lose valuable product due to excess foam, talk to us today.

The applications of silicone antifoams

Silicone antifoams are amongst the most efficient products used to control production foaming issues.  This selector guide describes a complete line of Mera Chemical Silicones antifoams which have been found particularly useful in many applications.

In selecting the best type and quantity of silicone defoamer, each application must be considered separately. In addition to the primary differences of the non-aqueous and aqueous system requirements, there are differences in the same process when formulations are changed.

Some of the factors are:

Chemical nature of the foam foaming agent
Foaming tendency of the agent
Solubility and concentration
Electrolytes, colloids or other surface active agents present
Temperature, pH and viscosity of the system
Processing equipment involved
End use of product containing the antifoam
It is therefore best to evaluate several antifoams in each system to determine type and concentration needed to assure optimum results.

      Excellent local company for Australian-made products. When buying sanitisers, customers can choose from unscented or a selection of essential oils. I asked about the possibility of an alcohol solution without glycerol to use for my masks … More instead of my hands, and both Angela and John, the lead chemist, spent lots of time clarifying exactly what I required. John even called me to check whether I preferred ethanol to the isopropyl I asked for, explaining the difference between the two. Really lovely people and affordable, Australian made sanitisers that I trust.

      Mera Chemicals provides excellent, locally made, bulk antiviral/antibacterial sanitiser and disinfectant required for Covid disinfecting. Essential oils make it smell really nice! The staff couldn’t be more helpful and access is easy.
