Polydimethylsiloxane (PDMS) is the older technical term for silicone. The chemical formula for PDMS is CH3[Si(CH3)2O]nSi(CH3)3. Albright Technologies provides rapid prototypes made of PDMS (silicone). When provided with a solid model, we can provide Polydimethylsiloxane (PDMS) parts in as fast as 5 business days. PDMS can be compression or injection molded. The material is commonly used for BioMedical and Medical applications, including components for microfluidics, catheters, implants, valves, punctual plugs, orthopedics and micro gaskets. We can also overmold Polydimethylsiloxane (PDMS) to various thermoplastics, metals and silicone rubbers.
There are a few reasons why Polydimethylsiloxanes (PDMS) are used in these applications, including the ability to reproduce features down to the submicron level, they are available in optically clear grades and they are generally considered to be inert, non-toxic and non-flammable. Most Polydimethylsiloxane (PDMS) use a platinum catalyst for curing, which allows processing at high temperatures and reduced curing time.
Polydimethylsiloxane (PDMS) can be supplied in various grades by major manufacturers such as Dow Corning, Wacker, Bluestar, Shin-Etsu, NuSil, Momentive and others. Albright stocks Polydimethylsiloxane (PDMS) in most durometers.
