What is PDMS?

Polydimethylsiloxane (PDMS) is the older technical term for silicone. The chemical formula for PDMS is CH3[Si(CH3)2O]nSi(CH3)3.

PDMS can also be referred to as dimethylpolysiloxane or dimethicone. PDMS is the most widely used silicone-based organic polymer. PDMS is optically clear, and non-toxic, and non-flammable. It is one of several types of silicone oil. Its applications range from contact lenses and medical devices to elastomers.

PDMS is also present in household items like shampoos (dimethicone is what makes your hair shiny and slippery), food (antifoaming agent), caulking, lubricants and heat-resistant tiles. Learn more about PDMS on Wikipedia.

We specialize in rapid PDMS prototypes

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.

Why use PDMS?

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.
