PBT
LASER WELDING PBT(Panasonic)
Panasonic has developed laser welding grade (PBT) that will improve the long-term reliability of sensor product part which is required "waterproof "and "airtight".
① Laser transmittance 72% (Wavelength：1064nm, Thickness:1mm)
② Hydrolysis resistance strength retention >90% (85℃×85%RH×1,000h)
③ VIS light transmittance (*Less than 600nm area) <3% (MBS230H33L Brown)
