Robust Roller Shutters
Soft-Touch TPEs for Automotive Roller Shutters
In specific instances, OEMs originally designed and prototyped rolling covers using TPU materials. Even though the material passed the scratch resistance test, the UV and chemical resistance assessments failed the validation protocols. Kraiburg TPE, Waldkraiburg, Germany, offered the customer the VS/AD/HM series as material solution. According to the manufacturer these compounds offer not only high scratch and abrasion resistance, they also provide good chemical compatibility and UV-stability.
In addition, the TPE compounds should have efficient injection molding properties such as good flow for high injection rates and short cycle times. They demonstrate good adhesion to polar thermoplastics in two-component applications not only with PC, ABS, PC / ABS blends, PU, ASA and SAN, but also with PA12 and PA6.
The VS/AD/HM series offers a Shore A hardness in the range of 60 to 80 with tensile strength up to 15 MPa and tear strength up to 30 N/mm.
