Polycarbonate (PC)
Verifiedpolymer· PC· Lexan· Makrolon
Polycarbonate (PC) is a transparent, amorphous thermoplastic polymer known for its exceptional impact resistance and optical clarity, making it significantly tougher than acrylic or glass alternatives. It is widely used in applications demanding durability combined with transparency—including safety glazing, automotive windows, protective equipment, and consumer electronics—and is preferred where repeated impact, thermal cycling, or dimensional stability under load are critical concerns. Engineers select PC when standard brittle plastics fail, when weight savings over glass are essential, or when processing flexibility and design complexity justify slightly higher material costs.

Regulatory Screening
Environmental
Safety & Biocompatibility
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
