Covestro Makrolon® 6487 RE PC Resin

Makrolon 6487 RE PC Resin Flame Retardant

Makrolon 6487 RE is a partially bio-circular polycarbonate resin (PC) with UL 94V-0/1.5mm and 5VA/3.0mm flame retardancy. Its medium viscosity, UV stabilization, easy-release properties, and opaque color options make it ideal for injection-molded safety-critical parts, combining sustainability (ISCC PLUS mass balance) with robust performance.

Features & Benefits

Uncompromising Flame Safety

It achieves UL 94V-0 at ultrathin 1.5mm and 5VA at 3.0mm, with high oxygen index (36%). Perfect for electrical housings or automotive components where fire resistance is non-negotiable.

Sustainable & High-Performance

Partially bio-circular via ISCC PLUS mass balance, reducing carbon footprint without sacrificing mechanical strength or UV stability. Ideal for eco-conscious industrial designs.

Easy Processing & Durability

Medium viscosity (MVR 9.0 cm³/10 min) and low molding shrinkage (0.6–0.8%) ensure smooth injection molding, while high impact resistance (>50% strain at break) extends product lifespan.
