At the K show this week, Venator will be promoting SACHTOLITH® TC additive – an innovative, soft, white, zinc sulfide that can improve the heat management capabilities of polymer systems, without adding electrical conductivity.
Continuing growth in the consumer electronics sector, and the rise in popularity of LED lighting systems, is increasing demand for polymers that can conduct heat. With products becoming smaller and lighter, designers are actively seeking out plastics that can mitigate the damage that heat can do in confined spaces – to replace the use of metals.
Compatible with Polycarbonate, ABS, Teflon™ and other resins, SACHTOLITH® TC additive is an ideal filler for plastics used in applications where a moderate amount of heat is created. With the ability to dissipate heat quickly and efficiently, applications for SACHTOLITH® TC additive include heat sinks for LED lighting systems, components and housings for consumer electronic devices such as phones, laptops and smart watches; plus switch boxes, fuses, and coverings for small electric motors and battery systems.
In addition to being a good conductor of heat, SACHTOLITH® TC additive has metal deactivating properties, which can improve polymer system longevity. As a result, this novel additive is suitable for use in applications where oxidative degradation can be accelerated by the presence of trace metals – for example, in wire and cable insulation. Chemically resistant on the pH scale between 4 and 12, SACHTOLITH® TC additive can be used in abrasion sensitive systems. It can also be used in glass reinforced plastic products, where it can provide a bright white color and heat conductivity, without breaking delicate glass fibers.
Commenting, Jorg Hocken, Global Application Manager at Venator, said: “Traditionally, the low thermal conductivity of polymers has held back their use in some applications. The development of SACHTOLITH® TC additive can help increase the number of applications polymers can be used in . Where product designers would historically have been reliant on the use of metals, they can now switch to using plastics – confident in their mechanical stability and their ability to disperse heat.”
During K, Venator will also be promoting TIOXIDE® TR 29 – a brand new titanium dioxide (TiO2) pigment. Venator’s highest performing white pigment for low moisture applications and demanding processing conditions, TIOXIDE® TR29 combines ultra-low moisture content, with excellent dispersion properties and a high packing fraction – and is designed for use in the manufacture of highly technical thin films, and in engineering polymers where moisture sensitivity is a consideration.
