FAQ

What is Poly(dimethylsiloxane) (CAS: 9016-00-6)?

Poly(dimethylsiloxane), also known as PDMS (CAS: 9016-00-6), is a synthetic polymer with the chemical formula (CH3)2SiO)n. It is a viscous, clear liquid with high thermal stability, hydrophobic properties, and low surface tension. PDMS is inert, non-reactive, and commonly used as a silicone-based material in various industries due to its flexibility and chemical resistance.

What are the main uses of Poly(dimethylsiloxane) (CAS: 9016-00-6)?

Poly(dimethylsiloxane) (CAS: 9016-00-6) is widely used in pharmaceuticals as a drug delivery medium, in industrial applications as a sealant and lubricant, in food-grade coatings, and in research for microfluidic devices and laboratory equipment. It is also found in cosmetics, medical devices, and as a component in silicone-based products due to its biocompatibility and versatile properties.

Is Poly(dimethylsiloxane) (CAS: 9016-00-6) safe?

Poly(dimethylsiloxane) (CAS: 9016-00-6) is generally considered safe when handled properly. It is non-toxic and inert, with low reactivity. However, direct skin contact may cause irritation, so gloves are recommended during handling. Food-grade PDMS is approved by regulatory bodies like the FDA, and safety standards ensure its use in medical and industrial applications without harmful effects.

How should Poly(dimethylsiloxane) (CAS: 9016-00-6) be stored?

Poly(dimethylsiloxane) (CAS: 9016-00-6) should be stored in a cool, dry place away from direct light. Keep it in a sealed, airtight container to prevent contamination and maintain stability. Storage conditions typically require temperatures below 25°C and minimal humidity. Avoid exposure to extreme heat or UV radiation to preserve its chemical integrity and prolong shelf life.
