APPLICATION: Laser welding of plastics
FHI has a wide assortment of dyes and blends compositions for effective absorption of laser radiation in the visible and near infrared spectral regions. We can submit custom formulations of dyes blends for blocking laser radiation in any desired spectral area. Our visible and NIR dyes have excellent thermal stability which makes them suitable for solid thermoplastic resin formulations and injection molding.
