When an LCM or FPC hot-press stack must manage heat, pressure, and electrical separation in limited space, a 0.26 mm thin green silicone sheet provides a compact buffer layer. Lixing lists thermal conductivity of 1.0 to 1.5 W/m·K, withstand voltage of at least 4 kV, and an operating range from -40°C to 200°C. Engineers should still review thickness, electrode geometry, and working voltage together.

A thin sheet keeps the press stack compact

The Thin Green Silicone Sheet has a standard thickness of 0.26 mm and is supplied as a gray-green roll. Its thin form suits LCM display bonding and FPC hot-press positions where fixture stack height is constrained. Required dimensions should be confirmed for each build.

One layer carries thermal and insulation duties

The product page lists thermal conductivity of 1.0 to 1.5 W/m·K and withstand voltage of at least 4 kV, with ASTM D5470 and ASTM D149 cited as the respective test methods. These values support a sampling decision, followed by validation at the actual thickness, pressure, and electrical conditions.

A flat, non-stick surface supports precision pressing

Lixing describes the sheet as powder-free, flat, and non-stick for FPC, IC, glass, and LCM hot-press environments. Those disclosed surface properties suit processes that need to limit material transfer, while fixture design, temperature, pressure, and cleanliness still affect the finished assembly.

Use E = V / d to interpret the electric field

For an approximately uniform field, E = V / d. E is electric-field strength in V/m, V is potential difference in V, and d is thickness along the field in m. Monash University explains this field relation, while ASTM D149 states that dielectric-breakdown results must be interpreted with specified test conditions. The relation assumes near-parallel electrodes and uniform thickness. It does not replace evaluation of edge fields, frequency, temperature, humidity, material defects, or the assembled device.

Treat 4 kV as a sampling input

The listed withstand voltage is a material data point, not a guarantee for every assembly. A useful inquiry includes working voltage, waveform and frequency, electrode edges, press temperature, pressure, dimensions, and thickness tolerance. Zhuhai Lixing Compound Material Co., Ltd. can then confirm the available configuration.

Separate thermal and electrical acceptance criteria

This gray-green sheet suits compact press locations that need heat transfer, buffering, and electrical insulation. For thermal-test interpretation, continue with the ASTM D5470 test-condition article, then define electrical validation independently.
