Kraiburg TPE is back again for CHINAPLAS with two innovative thermoplastic elastomer (TPE) products, notably the UV/HF and UV/HF/SF series for automotive industry, as well as the COPEC series for wearable personal devices.
The UV/HF Series parked under its THERMOLAST K is the material solution for applications requiring high UV resistance and high flowability, particularly automotive exterior components.
Based on styrene block copolymers, this type of TPE has the advantage of production flexibility that are applicable to a diverse range of products and can be customized via the choice of additives, dyes and other thermoplastics.
They are also less demanding in terms of processing parameters than other TPE materials, such as thermoplastic vulcanizates (TPV) and thermoplastic polyurethane TPU). As a result, they do not experience significant loss of UV resistance at critical processing parameters, such as high shear rates or elevated temperatures. Its use is not only confined to the automotive sectors, but for the consumer, industrial and medical sectors as well.
The material advantages of the UV/HF Series are easy flowability, superior processing behavior, and strong adhesion to polypropylene (PP). It is tested according PV3930 for outdoor use on typical applications such as cowls, gaskets, roof rims, water deflectors and window encapsulations. It uses injection molding as its processing method and meets the specifications of Volkswagen PV 3930 with hardness ranging from 52-92 Shore A.
Like the UV/HF Series, the THERMOLAST K UV/HF/SF Series is targeted towards automotive exterior components requiring high UV resistance, high quality surface finish and high flowability. Typical applications include cowls, gaskets, roof rims, water deflectors, window encapsulations and other exterior automotive applications.
Its hardness ranges from 49 to 86 Shore A and conforms to Volkswagen standard Kalahari dry heat PV 3929 and Florida moist hot climate PV 3930 weathering resistance.
In view of the demand for comfort, silky soft and irritation-free material in wearable devices, Kraiburg TPE has rolled out a new COPEC that is free of latex, polyvinyl chloride (PVC) and heavy metals.
It resists dirt and withstands the everyday external stresses such as UV radiation, skin oils and lubricating greases. More importantly, it is irritation-free for the end user in the wearable consumer electronics segment.
COPEC can be processed as part of dual-component injection molding with polycarbonate (PC) using a production approach which simplifies manufacturing, slashes cycle times and eliminates the need for additional work procedures.
The material is colorable with high stability and is being used on the flexible ear pieces of the new astrospec 2.0 safety glasses produced by uvex.
