Features Of Dow DOWSIL 9546 Silicone Elastomer Blend

  1. Soft, skin-friendly durometer (Shore A 10–20) for enhanced tactile comfort and conformability.

  2. Excellent thermal stability across –50 °C to 200 °C, maintaining integrity under repeated thermal cycling.

  3. Low compression set (<20% after 72 h at 150 °C), ensuring long-term sealing and rebound performance.

  4. Good adhesion to common substrates including plastics, metals, and glass without primers.

  5. Biocompatibility aligned with ISO 10993-5 (cytotoxicity) and USP Class VI testing protocols.

Typical Applications Of Dow DOWSIL 9546 Silicone Elastomer Blend

  1. Medical wearable devices requiring soft, flexible, and skin-contact-compatible elastomers.

  2. Sealing and gasketing solutions for automotive sensors and EV battery module enclosures.

  3. Consumer electronics housings and protective overmolds for buttons, grips, and interfaces.

  4. Food-grade appliance components including dishwasher seals and blender gaskets.

  5. Industrial soft-touch control panels and human-machine interface (HMI) overlays.
