1) High efficiency of heat transfer: the thermal conductivity is 150-300W/m.k;
2) Easy processing: flexible diaphragm, easy cutting and processing into any shape, can be repeated bending.
3) Light weight: density is 1.5-2.1g/cm3 ( about 1/3-3/4 of the aluminum and equivalent to 1/5-1/4 of the copper);
4) Low resistence: can be used for electromagnitic shielding.

Q1. Can we get some free samples from you?
A: Yes, you can get some free samples, but the shipping cost of samples should be paid by you.
A:We have obtain UL, SGS, ROHS ISO and REACH certificattes, approved by third party with testing report. we can provide you with the testing report of thermal conductive matrials to ensure our product quality.
A: We have thermal conductive silicone pad with different thermal conductivity including HC100, HC150, HC200, HC250,HC300,HC400,HC500, HCP100. And we have thermal conductive adhesive tape: HCT with PET as base material and HCTM without PET as base material. We also have thermal conductive graphite sheet apply in different electronic industries. GSH is apply on smart phone, GSB is for laptop , and GSM is for LED.
A: Yes , all the thermal conductive materials except HCP series, thickness no more than 0.5mm can add fiberglass as carrier.
A: Our products are widely used in various industries, including poower supply, LED lights, laptop, LED TV, Set top box, communication, heat transfer, chip IC, automotive electronics and photoelectricity etc.
A: Our thermal conductive silicone pad use silicone rubber as based material. The service life of silicone pad depend on the service life of silicone rubber. The silicone rubber industry recognizes a 20-year life for silicone rubber when used within specified operation parameters.
A: The shelf life is a measurement of stable storage life in specified storage conditions. Shelf life for thermal conductive gap filler pad is one year after date of manufacture. For thermal conductive gap pad with adhesive, the shelf life is six months after the date of manufacture. After these dates, inherent tack and adhesive properties should be re-characterized.
A: Yes, all our thermal conductive materials are isolating with the voltage endurance over thousands of volt.
