Electronics Silicones: High-Performance Sheeting Solutions

As electronic devices grow smaller, denser, and more powerful, managing thermal stress, electrical insulation, and environmental exposure becomes critical. Standard elastomers break down under localized heat, high voltages, or aggressive thermal cycling. ElastaPro Electronics Silicones provide the durability, dielectric performance, and thermal endurance required to protect sensitive microelectronics, printed circuit board assemblies (PCBAs), and ruggedized enclosures.

Engineered and manufactured in the USA, ElastaPro produces high-grade solid silicone sheeting designed to meet strict commercial, automotive, aerospace, and defense electronics specifications.

Performance Properties of ElastaPro Electronics Silicones

Silicone rubber offers an inherent molecular structure that excels where traditional rubbers fail. ElastaPro compounds solid silicone sheeting tailored to the exact mechanical and thermal parameters your application demands:

  • High Dielectric Strength: Functions as an exceptional electrical insulator, preventing electrical arcing, short circuits, and dielectric breakdown across high-voltage components.

  • Broad Thermal Range: Maintains flexibility and structural integrity from -103°F to 450°F (-75°C to 232°C), with specialized high-temperature formulations reaching up to 500°F (260°C).

  • Thermal Management: Serves as a reliable substrate for thermal interface pads, heat spreader backing, and dissipation layers to draw heat away from active components.

  • Low Outgassing: Formulations designed to minimize volatile condensable material (VCM), preventing lens fogging and sensor contamination in optical or sensitive sealed electronic units.

  • Flame Retardancy: Available in compounds engineered to meet UL 94 V-0 and UL 94 HB standards for self-extinguishing flame resistance.

  • Environmental & IP Sealing: Highly resistant to moisture, dust, ozone, UV radiation, and outdoor weathering, ensuring long-term IP67/IP68 ingress protection for electronic enclosures.

Outdoor & Ruggedized Enclosures

NEMA and IP-rated electronics enclosures rely on ElastaPro solid silicone sheeting for long-term compression set resistance. Unlike organic rubbers, silicone does not harden or crack when exposed to solar radiation or sub-zero climates, preserving tight seals over multi-year deployments.

Automotive & Electric Vehicle (EV) Electronics

From battery management systems (BMS) to powertrain sensors and autonomous driving radar units, ElastaPro silicone materials provide essential thermal isolation, vibration damping, and high-voltage dielectric protection.

Aerospace & Defense Microelectronics

Where failure is not an option, ElastaPro manufactures military- and aerospace-grade silicone sheeting designed to withstand extreme thermal shock, altitude pressures, and aggressive environmental exposure.
