The increase in conductivity is about four times that of PG-SN grade or more than four times better than copper. EMI shielding protects sensitive applications. High in-plane thermal conductivity up to 1800 W/m-K. High Thermal-Conductivity Material Opens Up Future Opportunities. We have made thermal and electrical transport measurements of uncompressed pyrolytic graphite sheet (uPGS), a mass-produced thin graphite sheet with various thicknesses between 10 and 100 μ m, at temperatures between 2 and 300 K. Compared to exfoliated graphite sheets like Grafoil, uPGS has much higher conductivities by an order of magnitude because of its high crystallinity confirmed by … Pyrolytic graphite sheet (PGS) is a synthetically made thermal interface material with high thermal conductivity and a thin graphite film structure (thickness measured in microns). Extremely thin: offered in thicknesses of 0.017mm to 0.100mm (17 microns to 100 microns). <> Graphite's sheet-like crystals known as graphene are stacked on top of each other, allowing for extremely high in-plane thermal conductivity (x-y direction) compared to its through-plane thermal conductivity (z direction). Thermal Conductivity Watts/m ºC 300 ‘a b’ direction 3.5 ‘c’ direction Electrical Resistance Ohm*cm 0,5x10-3 ‘a b’ direction 0,5 ‘c’ direction Crystal Structure — Hexagonal Melting Point ºC Sublimes at 3650 This material is RoHS compliant and can be die-cut, press-formed, or laminated with polyester to improve electrical insulation and/or pressure-sensitive adhesive tape for easy attachment to a surface. Offered with adhesives for fast installation (peel-and-stick attachment). PGS(Pyrolytic Highly Oriented Graphite Sheet) is made of graphite with a structure that is close to a single crystal, which is achieved by the heat decomposition of polymeric film. endobj Testing the Thermal Conductivity of Pyrolytic Graphite Sheets The use of graphite dates back many hundred years, and may possibly have been used in some cases before the advent of written records. PGS is used in many electronic devices as a heat spreader. Panasonic PGS or Pyrolytic Graphite Sheet is a heat spreading material with high thermal conductivity. A wide variety of high conductivity graphite sheet options are available to you, such as type, grade. However, compared to natural graphite, the more perfect lattice comes at a higher price. It can be cut into custom shapes, making it extremely useful for applications with limited space. H‰ÄUM‹ãF½òê(CÜÛßÇì–MÈB°a»KĞÈm[A–IŞa! Eliminates the need for fans and heat pipes. endobj Lightweight when compared to its metallic counterparts such as aluminum or copper. PGS is a competitive conductive sheet with high thermal conductivity and high flexibility. Pyrolytic graphite thermal interface pads provide heat spreading for engine management, electronic suspension, braking systems, communication and multimedia systems, and vehicle lighting and controls. This material is lightweight and highly flexible. Recently, a new exible graphite sheet, pyrolytic graphite sheet (PGS) [9, 10], has been invented. Property Unit Pyrolytic Graphite. 2. It provides superior heat spreading for battery cooling and digital displays in mobile devices and electronics. Can be laminated with plastics, metals, or foam to improve performance. Pyrolytic graphite sheets can be used in many industries, including but not limited to Mobile Electronics, Aerospace, Automotive, and Telecommunications, all of which benefit from the improved thermal conductive performance.

HPMS pyrolytic graphite sheets offer thermal conductivity up to 1800 W/m-K and are very thin, which allows for easy attachment to a variety of heat sink or component surfaces. This option is ideal for applications where both electrical isolation and thermal management are required. It has a function to absorb heat by resin and release the heat by utilizing high thermal conductivity of PGS Graphite sheet. ë4F†sã¹Ò-¾tD(lÖòÕ{•²¦¢œÕşgÌü—a:%E4©˜(ZÙÆ“kŞ:�M:H…‰ò±RÊR¶Ä\¥` s•‚uÔÑôÈ EMI shielding and absorbing to protect sensitive electronic parts.
