Potting and protection for chips and high-precision electronic components require not only physical shielding but also flame-retardant and insulating electrical safety. Ordinary potting materials often suffer from poor insulation (leading to circuit failures) or low flame resistance (posing fire risks), making it difficult to meet electronic equipment safety standards. A silicone rubber specially designed for chips combines UL94 V‑0 flame retardancy and ultra-high insulation, together with low shrinkage, low water absorption and low oil bleeding. It builds a safe and durable protective barrier for electronic components, fully solving electrical safety and protection pain points.
Its electrical safety performance sets an industry benchmark. With a flame-retardant rating of UL94 V‑0, it self-extinguishes quickly upon contact with open flame, without sustained burning or molten drips, effectively preventing fire spread and reducing the risk of electrical fires caused by short circuits.
Its insulation performance is exceptional:
-
Volume resistivity reaches 1.0×10¹⁴ Ω·cm, strongly isolating current conduction and avoiding leakage or short circuits in chips and components;
-
Dielectric strength of 18 kV/mm and breakdown resistivity ≥ 20 MV/m ensure resistance to breakdown even under high voltage;
-
Stable dielectric constant of 3.2 (at 1 MHz) ensures no interference with signal transmission, perfectly meeting the electrical requirements of high-precision electronics.
In terms of physical performance, it delivers triple guarantees: low shrinkage, low water absorption and low oil bleeding.
-
Shrinkage after curing is less than 1.5%, far lower than ordinary potting materials, avoiding gaps and maintaining tight bonding with components to prevent moisture and impurities from intrusion;
-
Water absorption after long‑term immersion is below 1%, resisting humidity without compromising insulation or protection;
-
Extremely low oil bleeding prevents oil precipitation that could contaminate chips or corrode precision circuits, ensuring long‑term stable operation.
As a solvent‑free two‑component system, it forms a gel‑like material that effectively relieves stress from thermal shock and mechanical vibration, maintaining stable mechanical and electrical performance in complex environments.
From potting of various electronic chips and semiconductor components to filling and sealing of industrial precision sensors and automotive electronic sensitive parts, this silicone provides dual advantages of flame retardancy and insulation, safeguarding the safe operation of electronic equipment.
