Density (g/cm3) 2.5g/cc High Efficiency Phase Change Thermal Interface Materials
PCM(phase Change Material) is a substance that changes shape with temperature and provides latent heat. The process of changing the material from a solid to a liquid or a solid state is called a phase transition, and the phase transition material will absorb or release a large amount of latent heat.

Product Details
Package And Shipping
Q:What’s the thermal conductivity test method given on the data sheet?
A: All the data in the sheet are tested out by the third party. ASTM D5470 is utilized to test the thermal conductivity.
Q: How to find a right thermal conductivity for your application?
A: It depends on the watts of power source, ability of heat dissipation. For any customers, please contact us for the technical support.
Q: Are thermal pads offered with tacky?
A: Yes, all the thermal pads have its inherent tacky. All the models are natural tacky for two sides, except for the LCP series ,only one side has natural tacky. LCB series thermal pads can be cover 3M glue with strong
adhesive.
Q: Are thermal pads reworkable?
A: It’s depend on the application and the pad being used. Thermal pads have been reused before, however,it’s up to the judgment of product designer, to see whether the pads could withstand reuse.
Q:Will the heat make the thermal pads softer?
A: ShoreC 20~80 ,there is no significant change in the hardness of thermal pads, as gap filler.
Q: What’s the tolerance for the thickness?
A :Normally ±0.1mm.
Q: Are the thermal pads electrical insulating?
A: Yes, all thermal pads are electrically isolated.
Q: What’s the shelf life for thermal pads?
A: Shelf life for thermal pad is one year after the date of manufacture. For the pads with adhesive, the shelf life is 6months after the date of manufacture. After these dates, all the characters should be retested.
Q: Can the thermal pads be with fiberglass?
A: YES, we could have thermal pads with fiberglass center to improve customer specific requirements for the tensile strength.LCP series has fiberglass on its surface, all other models will be made at your requirement.
