Ultramid® T 4381 LDS SW23271

About
Glass fibre and mineral reinforced partially aromatic polyamide for injection moulding. Good toughness, stiffness and strength, low water absorption, high melting point (295 °C). The product is especially tailored for laser direct structuring (LDS). The structured areas can be metallized selectively. The compound is intended specifically for the use in the process of manufacturing conducting path designs according to the German application of the patent 101 32 092 of LPKF Laser & Electronics AG (Osteriede 7 – 30827 Garbsen – Germany). The use of this process asserts a claim for compensation. After purchasing a LPKF laser system the claim is satisfied. Please contact directly LPKF Laser & Electronics AG (http://www.LPKF.de).&&
