Because nylon 6 has a higher laser transmission rate than PBT and nylon 66, BASF is optimistic about the application prospects of laser-welded nylon 6 grades and believes that it will help broaden the new application areas of nylon 6. The Nd-YAG laser with a wavelength of 1064 nm (nanometer) has a transmittance of 72% for a 2 mm thick U1tramid B3G6 1T. Therefore, the product has a short molding cycle and is suitable for processing complex shapes and/or thick-walled products.
One application of the U1tramid B3G6 1T is the automotive engine intake assembly, which was previously assembled using vibration welding. This kind of laser welding nylon 6 grade has some products. The advantage is that it will not produce surface weld beads when welding, the surface is relatively smooth, and the air will not generate turbulence at the weld seam. The new black grade has no apparent difference from the normal black nylon 6 U1tramid. The long-term use temperature is also 130°C and the short-term heat resistance is 150°C.
BASF launches black laser nylon 6 brand
BASF, Germany, added black laser nylon 6 U1tramid B3G6 1T to its black laser-welded PBT and laser-welded nylon 66 grades.
