QSi Develops its Latest UL Recognized Component for Electronic Potting and LED Encapsulation

December 12, 2013

As the Newest Potting and Encapsulating Silicone Elastomer, QSil 553LV Features Valuable Properties for Heat Dissipation and is UL 94 V-0 Listed.

RICHMOND, Va. – Meeting UL requirements for flame retardancy, the addition curing QSil 553LV is a silicone rubber designed to benefit electronic potting applications, such as power supplies, LED, circuit and electronic modules. Its physical properties enable this material to withstand extreme temperatures, protect sensitive components from moisture and debris, while being readily repairable.

QSil 553LV has a low viscosity allowing convenient dispensing and an easy flow throughout complex parts. This compound will cure in closed environments. It will not outgas or produce any byproducts since it is 100% silicone solids, containing no solvents.  Its long work life of 100 minutes will also allow time for air bubbles, which may be entrapped during dispensing, to dissipate.

“QSil 553LV is a great general purpose thermal management material,” said Phil McDermott, vice president of technology. “It balances both thermal conductivity and rheology, while maintaining a great cost-performance relationship.”

Electronic components often experience thermal expansion during temperature increase or collapse at decreased temperatures. To minimize CTE strain, QSil 553LV is a low modulus material, providing excellent flexibility as well as shock and vibration resistance. It will maintain its physical properties between the temperatures of -55°C up to 240°C.

Potting & Encapsulating Silicones

January 20, 2012

Quantum Silicones’ Potting and Encapsulating products are used to provide a flexible, protective barrier against a variety of environmental factors.  Silicones are used in a wide array of applications – typically electronics – to provide excellent electrical properties as well as protection against moisture, debris, heat shock and vibration.

 

These two-component potting compounds and silicone encapsulants are generally used when a deep section cure is required.  They can be cured at either room temperature or accelerated with heat and are also available in a wide range of viscosities.  QSi’s two-component encapsulants can also be either machine or hand dispensed.  Once cured, its hardness can range from a gel-like consistency to a hardened rubber.

 

Quantum Silicones’ Potting and Encapsulating series are used for many generic applications, but were also  developed for specific applications requiring optical clarity, thermal conductivity, flame resistance, UL rated or extreme service temperatures (-55C to 204C).
