Silicone antifoams and defoamers are new and efficient modified silicone defoaming agents for water based drilling mud systems. Silicone anti-foaming agents can prevent foam from forming, while silicone defoamers can maked existing foam collapsed rapidly. The primary active ingredients are polydimethylsiloxane (PDMS) and white carbon black. Silicones have low surface and interfacial tensions which enable them to flow easily over the film and make the foam wall thin and collapse. Bichain is a reliable polydimethylsiloxane PDMS manufacturer and supplier of silicone antifoam defoamer in oilwell drilling, cementing and fracturing. We provide high quality defoaming products at low polydimethylsiloxane prices for sale. CAS 63148-62-9.
