Name: Dow SYLGARD 535 Silicone Dielectric Gel
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow SYLGARD 535 Silicone Dielectric Gel

Ultra-low modulus silicone gel formulation for stress-free encapsulation and conformal protection of sensitive electronic components.
Excellent dielectric strength and stable electrical insulation properties across wide temperature and frequency ranges.
Non-corrosive, platinum-cured chemistry with no by-products—safe for use with copper, aluminum, and delicate semiconductor surfaces.
Thixotropic behavior enables easy dispensing and minimal flow after application, supporting precise localized coverage.
Outstanding long-term thermal stability and resistance to thermal cycling from –50 °C to +200 °C.

Typical Applications Of Dow SYLGARD 535 Silicone Dielectric Gel

High-voltage power electronics: IGBT modules, inverters, and EV traction inverters.
LED lighting systems requiring thermal management and electrical isolation in compact form factors.
Renewable energy systems: solar microinverters, DC optimizers, and battery management system (BMS) sensors.
Automotive electronics: onboard chargers (OBC), DC-DC converters, and ADAS sensor housings.
