Polydimethylsiloxane (PDMS) belongs to a group of polymeric organic silicon compounds that are commonly referred to as silicones. The chemical formula for PDMS is CH3[Si(CH3)2O]nSi(CH3)3. Albright Technologies does rapid prototyping using PDMS (silicone). When provided with a solid model, we can provide Polydimethylsiloxane (PDMS) parts in as fast as one day. PDMS can be compression or injection molded and are commonly used for BioMedical and Medical applications, including components for a microfluidics, catheters, implants, valves, punctual plugs, orthopedics and micro gaskets. We can also bond Polydimethylsiloxane (PDMS) to various thermoplastics, metals and silicone rubbers.
There are a few reasons why Polydimethylsiloxanes (PDMS) are used in these applications, including its ability to reproduce features down the submicron level, it is available in optically clear grades and it is generally considered to be inert, non-toxic and non-flammable. Most Polydimethylsiloxane (PDMS) use a platinum catalyst for curing, which allows processing at a high temperature and reduces the curing time.
Polydimethylsiloxane (PDMS) can be supplied in various grades by major manufacturers such as Dow Corning, Wacker, Blue Star, Shin Etsu, NuSil and others. Albright stocks Polydimethylsiloxane (PDMS) in most durometers.
