Thermoplastics soften at 50-300°C depending on material. Laser cleaning requires pulse durations under 20 ns and fluence below 0.5-2 J/cm² to remove surface contaminants without reaching glass transition temperature (Tg) or melting point (Tm).
Wavelength Selectivity for Plastics
Many thermoplastics are transparent to 1064nm IR laser light, allowing contaminants to absorb energy while the substrate transmits it. UV wavelengths (355nm) are strongly absorbed, creating surface heating risk better suited for thermoset plastics.
Mold Release & Contaminant Removal
Injection-molded thermoplastics carry silicone and fluoropolymer mold release residues that block adhesion for painting, bonding, or plating. Laser cleaning removes these micron-thick layers without surface etching or solvent residue.
Medical & Automotive Applications
Polycarbonate lenses, ABS dashboards, and nylon components require contamination-free surfaces for bonding. Laser cleaning meets ISO 10993 (biocompatibility) and automotive OEM standards without chemical residues or abrasive damage.
