DescriptionThis heat sink paste is made of premium material, which can withstand long-lasting use. Features the silicone grease material, which has high durability, not easy to deform. Fine workmanship, ensures practicality.Features-Color:Black-Material:silicone grease -Size:6.00X6.00X6.00cm/ 2.36X2.36X2.36inThermal conductivity: 0.25 Celsius degree - in 2/w Thermal conductivity: >4.8w/mk Specific gravity: >2.5g/cm3 Operating temperature: -50 c to 120 Celsius degree - High thermal conductivity, high insulation, high temperature resistance, low oil content and non-corrosive. - Working principle: Fill the gap between the heating element and the cooling device; increase the contacting area to achieve the best heat conduction effect. - How to use: A small amount of silicone oil floating on it is normal. Please stir well before use. - Note: Keep the coating surface clean and apply directly with tools (such as scrapers, finger cots, etc.). - Special design and it is in fine craftsmanship. It is the best replacement for your old, broken one.
