GTP150 Versatile Heat Sink Silicone Thermal Pad Conductive Rubber Sheet for Notebook Power Supply

With the model number GTP150, this versatile heat sink silicone thermal pad is a moldable thermal interface material built from conductive high temperature silicone rubber, supplying dependable heat dissipation together with reliable electrical insulation. Supplied in thicknesses from 0.5 mm to 15 mm and in grey or black, the pad is soft enough to be hand-cut, die-cut, or molded into complex shapes, and it presses into place with double-sided adhesive so that it stays exactly where the designer intends. Its continuous use window of -40°C to 160°C and a wider operating ceiling of -40°C to 200°C make it suitable for laptops, power supplies, LED fixtures, automotive electronics, and other assemblies where both cold starts and sustained heat are part of the workload. Because the rubber body isolates the component electrically while still conducting heat away to the heat sink, engineers can cool live parts without adding an extra insulator, shortening the bill of materials and simplifying the mechanical stack.

• Conductive Silicone Rubber Body: The filled silicone rubber conducts heat efficiently away from processors, power devices, and LED boards while keeping the joint electrically safe.
• Excellent Electrical Insulation: A volume resistivity of 1.0×10¹² Ohm-cm and a withstand voltage above 4.0 kV/mm let the pad sit directly between live electronics and grounded heat sinks.
• Moldability for Complex Parts: The material can be molded, die-cut, or trimmed to irregular outlines, so unusual board shapes and multi-level stacks are handled without special tooling.
• Wide Temperature Range: Continuous use from -40°C to 160°C and an operating range up to 200°C keep performance steady through thermal cycling and harsh environments.
• Double-Sided Adhesive: Pre-applied adhesive on both faces holds the pad to the component and the heat sink, speeding assembly and preventing shifting during vibration or transport.
• Low Thermal Resistance: A thin, uniform contact layer at modest pressure transfers heat quickly and keeps component temperatures within their design margin.
• Flexible and Easy to Customize: Available in multiple thicknesses and colors, with free samples for evaluation and custom sizing to match each project.

The GTP150 pad fits comfortably into most consumer and industrial thermal designs. In notebooks and desktop computers it cools CPUs, GPUs, SSDs, and power delivery stages. In smartphones and tablets it manages heat around compact processors and battery areas. In LED lighting it carries heat from the LED board to the housing to protect lumen output. In power supplies and adapters it drains heat from switching devices and transformers. In solar panels, automotive electronics, industrial control cabinets, and medical devices, the combination of conductivity and insulation keeps sensitive circuits inside their safe temperature band. Because the sheet is moldable and adherable, it also suits tight, irregular assemblies where a rigid interface would not fit.

Each GTP150 silicone thermal pad is supplied with protective release liner, cushioned with foam, and packed in export-grade cartons, with packaging arranged to customer requirements where needed. The production process is certified to ISO9001, ISO14001, and TS16949, so batch-to-batch consistency is maintained for thickness, color, withstand voltage, and resistivity. Low minimum order quantities and free samples make it straightforward to evaluate the pad before a volume program, and a supply ability of up to 1,000,000 pieces per day supports rapid expansion. With a typical delivery time of about 7 days and a payment term of 30% T/T in advance with the balance before shipment, the pad is ready to slot into your next thermal project, and our team will help you choose the right thickness, color, and adhesive configuration.
