Laser Marking of Polypropylene and Polyethylene Plastics Using Fiber Lasers
Laser marking and engraving on polyolefin plastics, such as polypropylene and polyethylene, is difficult due to their polymeric properties, and there are different types ranging from homopolymer and copolymer polypropylenes including HDPE, LDPE, LLDPE and others that intrinsically mark differently. When developing a product to be laser marked, engineers should consider which grade is best […]
Laser Marking PPS Polyphenylene Sulfide Using Fiber Lasers
Abstract Marking and engraving on PPS (polyphenylene sulfide) is very difficult because it can withstand high temperatures when heated with a laser. Recent advancements in colorant technology, laser-specific carbon blacks, and fiber lasers enable high-contrast, light-colored, scratch-resistant marking of black glass-filled PPS, and certified by Yellow Card. This significant advancement enables the marking and micro-marking […]
New Anti-Counterfeiting Authentication Technology in Pharmaceuticals and Cosmetics Packaging
Authentication by a Single Breath Guarantees Genuine Products. SNOWLEOPARD®, developed by The SABREEN Group, is the next generation of anti-counterfeiting and brand protection technology, that requires only a single breath (warm vapor mist) to authenticate hidden indelible covert codes. Invisible inscription and authentication methods are highly engineered to prevent counterfeit products from entering the supply […]
Adhesion Bonding, Contact Angle, and Surface Properties of Polyamide Nylon
Polyamides, also known as nylons, are high-performance plastics with excellent chemical resistance. Nylons are hygroscopic and absorb moisture from the air. Moisture in and of itself causes adhesion problems. Nylon is hydrophobic and has low surface wettability. Question – Is nylon hydrophobic, hydrophilic, or maybe both? A polyamide is a polymer containing repeating amide (–CO-NH–) […]
How to Laser Mark and Engrave Nylon (Polyamide) Plastics with Fiber Lasers
Abstract Users of fiber lasers have difficulty marking or engraving nylon. The key to achieving high-quality marking contrast is to incorporate laser enhancing additives into the nylon material during the molding process, whether using color concentrate or precompounded materials. The benefits of laser marking nylon have transformed many industries, including firearms by enabling unique part […]
