Insulating Pads & Films
These cost effective thermally insulator pads and films provide electrical insulation between devices and their heat sinks or enclosures. Their superior breakdown voltage makes these interface materials ideal for high power electronics. The pads and films are easy to use and apply while optimizing the thermal joint between heat sink and heat source.

Products Features:

◇Thermally conductive insulators are designed to be clean, grease-free, flexible and convenient assembly .The combination of a tough carrier material such as fiberglass or Polyimide and silicone rubber which is conformable, minimize the thermal resistance from the case of a power semiconductor such as MOSFET to the heat sink.
◇All TCI materials electrically isolate the semiconductor from the heat sink and have sufficient dielectric strength to withstand high voltage. They are also strong enough to resist puncture by the facing metal surface by screw driver and clip mounted application
◇Excellent Reliability

How To Select the Right Thermal Interface Materials for your new application?

Pls feel free to contact us as Thermal Management Solutions available in SinoGuide.

Q1: Can I get free sample?

A1: Yes, SinoGuide is glad to offer free samples if you are a qualified and returning customer, however, if the sample is expensive, like large size , SinoGuide has to charge some basic cost of the sample. For the new customer, samples fee will be deducted from the initial bulk order.

Q2: Are you a factory or a trading company?

A2: We are the professional manufacturer of the thermal materials for over 10 years.

Q3 : How to ship the order?

A4: SinoGuide usually sends packages by air, which is fast. There are many good international couriers for options; DHL, UPS, FedEX, and EMS are the most popular. If a buyer has any DHL, UPS, FedEX account, we can ship the package under your account. For bulk order, SinoGuide usually ship by sea, a sea shipment will require much more Customs and shipping documentation than air shipment.

Q4: Is there promotion price for big buyer?

A4: Yes, if you are a big buyer in a certain area, SinoGuide will offer you a promotion price, which will help you to start our business there. Long term cooperation buyer will have better prices.

Q5: Does your product have any certificate?

A5:Yes, our product has ROHS, UL certificate.

Q6: Can I get the customized sample?

Q6: Yes, we can offer different thickness and different thermal conductivity for you.

If you do not have clear idea, you can inform us the product application and the power of your product, we can recommend right thermal pad for you.
