KRAIBURG TPE offers a range of new thermoplastic elastomers developed specifically for PP adhesion and excellent UV resistance in automotive applications.
The new compounds in the THERMOLAST K series are mainly used in automotive exterior applications such as water deflectors and window packaging.
Plastics used in automotive exterior applications can be affected by severe weather, especially on vehicles. These applications often require weather-resistant plastic materials that can withstand the negative effects of UV radiation on the visual appearance and mechanical properties of automotive parts.
Therefore, it is best for weather-resistant plastics to have a certain UV resistance, because UV radiation will have a particularly large impact on materials used outdoors.
Weather resistance and adhesion to PP
The latest THERMOLAST K UV / HF / SF series has extremely strong UV and weather resistance as well as adhesion to PP. Thermoplastic elastomers can be processed into precise and uniform surfaces without welding.
This is achieved due to the excellent flow properties of TPE. These TPE compounds can be easily and accurately processed through a two-component injection molding process. In this process step, they adhere very well to the hard component PP. Through the multi-component injection molding process, the best bonding performance is obtained; no additional assembly steps are required, and the cycle time of the component is reduced.
Passed the weathering test of Kalahari & Florida
UV / HF / SF THERMOLAST K offers many benefits such as increased design value, economical processing and expansion of product functions. It can meet the typical requirements of different fields of use and the automotive industry, including the PV3929 Kalahari natural weathering test and the PV3930 Florida outdoor use test with a 2-year cycle.
This ultimately provides more possible external applications for the automotive industry, which will need good weather-resistant materials to withstand the changing weather in the Asia Pacific region to ensure vehicles have better performance over a longer period of time, thereby saving User costs for vehicle maintenance.
