ABOUT QSi | Quantum Silicones

QSi was founded in 1997 by its two current principals, Tom Loman and Phil McDermott.  Both Loman and McDermott have extensive experience in the silicone industry.

Loman held several management positions with GE Silicones in sales and marketing. McDermott started his career at the GE Research & Development Center and then transferred to GE Silicones as an elastomer chemist specializing in two component silicone elastomers.  They have since put together a great team of chemists, technicians, chemical operators, sales individuals, etc. to emerge as a leader in specialty silicone technology.

The manufacturing site in Richmond, Virginia utilizes the latest in silicone compounding and equipment.  The state of the art laboratory is fully equipped for testing and development.

QSi’s original vision was to manufacture specialized silicone elastomers.  This vision remains constant today.  We are dedicated to our customers in development, supply, service and quality.  QSi has a full line of industry proven mold-making products for a wide range of applications such as architectural, statuary, special effects, prototyping and many more.  Our extensive line of silicone gels are currently used in aerospace, automotive, lighting, and electronic applications just to name a few.  We also offer silicone encapsulants, potting compounds, adhesives, conformal coatings, fabric coatings and optically clear elastomers.  These products can be made to enhance or transmit light, conduct heat away from a device and withstand extreme temperatures with high dielectric integrity.  QSi also offers products for optical systems with high refractive indices.  In addition, we currently have 15 UL listed products for a variety of applications.
