High heat resistant, high-speed markable and tamper-proof
Product Features
Meets Chinese GB/T 25978 (P.R.C.) Type A to F, European KBA and American NHTSA
High heat resistance for applications on engine or transmission (F-type label, 1600h@150°C, according to GB/T 25978)
High energy absorbing layer for high-speed marking to meet short cycle times
All product featuresProduct description
tesa® 6950 is a high heat resistant two-layer, brittle acrylic laser markable film with a special adhesive system. The “UV-Footprint” adhesive leaves an UV-detectable trace on most surfaces as required by GB/T 25978 (P.R.C.) and NHTSA §541.5 (USA) The label is destroyed upon any attempt of removing and tampering and leaves a visible trace (damage of information and label) to prevent re-using and cloning. tesa® 6950 is specially designed to also fulfill the requirements of GB/T 25978 (P.R.C.) for A to F-Type labels (incl. engine and transmission). Marking and cutting are achieved by laser in one step, which makes it possible to realize any desirable label variation and format using only one material
