          Momentive launches products that address the challenges of LED lighting to create heat transfer and heat dissipation

          Momentive Advanced Materials has introduced a new line of thermally conductive silicone products, including TIA series of cured hot melt adhesives and adhesives, as well as TIS series of thermal greases to help LED lighting manufacturers address the current heat transfer of LED lighting components. Heat dissipation problem.

          Momentive's TIA hot melt adhesives, including the TIA221G and TIA216G, are liquid materials for heat dissipation that can be used in a variety of thermal conductivity levels, viscosities and cure profiles to meet a wide range of design needs. New hot melt adhesives are easy to use and help extend the life of LED bulbs by helping to manage the heat generated by the voltage regulator driver. Since the driver is a three-dimensional design and is typically packaged in a bulb fixture, it is often necessary to use a liquid heat sink material that conforms to the illumination assembly design and can flow into the driver cavity to form a slave to the bulb fixture. Hot channel. Because the liquid hot melt adhesive fills the gap between the driver and the peripheral fixture and can be cured at room temperature or by accelerated thermal curing to form a soft elastomer, the TIA series absorbs thermal stress due to its soft material and can Provide a heat sink.

          TIA thermal adhesives, including TIA250R and TIA600R products, are designed for applications requiring mechanical adhesion with room temperature and thermally accelerated curing formulations that adhere strongly to a wide variety of substrates.

          The TIS series of thermal greases, including the TIS380C, cure at room temperature and can be used to minimize thermal resistance in LED lighting assemblies. Eliminates stress for precision fittings and ensures that oil leaks and volatiles are kept to a minimum, helping to achieve stability in high temperature environments.

          Momentive's TIA hot melt adhesives, adhesives and thermal grease form a heat dissipation path between the LED display panel and the heat sink to help protect the LED during heat dissipation. TIA products are in liquid form, making it easy to accurately apply a precise amount of material to a specific location, and finally solidify into a thin glue line. This helps to increase the overall efficiency of the heat transfer process. The new product offers a thermal conductivity of 1 ? 6 Watt/mK and can be applied by drop or screen printing depending on the grade.

          In addition, Momentive offers the InvisiSil* LED Silicone product line to help address performance and reliability issues in LED packages. InvisiSil materials can be used as a secondary sealant or as a plastic grade for injection, compression or transfer molding systems. The sealant has an extremely high light transmittance (>98%) even after being heated (150 ?° C) and irradiated with ultraviolet light (400 nm, 800 nm) irradiated with a refractive index of 1.4-1.5 which can obtain the maximum amount of light for 1000 hours.

          Momentive also offers silicone adhesives that can be used to glue lighting components such as spherical caps. These adhesives resist heat and yellowing under a variety of different operating conditions.
