Product Introduction
PBT GF20 GF30 Laser Markable | Halogen-Free FR V0 with Glass Fiber for Permanent Traceability
This PBT laser markable halogen-free flame retardant glass fiber reinforced compound is an advanced engineering thermoplastic that combines three critical functionalities in one material: permanent laser marking capability, environmentally friendly halogen-free flame retardancy, and glass fiber reinforcement for mechanical strength.
Designed for applications requiring traceability, safety, and durability, this material achieves UL94 V0 flame rating while enabling high-contrast laser markings (white mark on black/dark backgrounds) using standard Nd:YAG or fiber lasers (1064nm). The markings are permanent, wear-resistant, and solvent-resistant, making it ideal for automotive, electrical, and industrial components requiring part identification, serial numbers, barcodes, or brand logos.
Key Properties
Laser Markable – High contrast white marking on black base, permanent and durable
Halogen-Free Flame Retardant – Phosphorus-based system, UL94 V0 rated
Glass Fiber Reinforced – Available in GF20 (20%) and GF30 (30%) grades
High Mechanical Strength – Tensile strength up to 135 MPa (GF30)
Excellent Heat Resistance – HDT up to 215°C (1.8 MPa)
Good Dimensional Stability – Low warpage, controlled mold shrinkage
Chemical Resistant – Resists oils, greases, and solvents
RoHS / REACH Compliant – Meets global environmental regulations
Injection Moldable – Good flow for complex parts
How It Works
The laser marking additive in this compound absorbs laser energy and undergoes a controlled photochemical reaction or foaming mechanism, creating visible contrast without damaging the surrounding material. This enables:
