Features & Benefits
Flame Retardant & Safety Certified
Covestro Makrolon 9415 meets stringent UL 94 V-0 (1.5 mm) and 5VA (3.0 mm) standards, reducing fire risks in critical applications like electrical enclosures without compromising structural integrity.
Superior Strength & Impact Resistance
10 % glass fiber reinforcement boosts tensile modulus (3800 MPa) and Charpy impact strength (150 kJ/m² at 23°C), ensuring durability in high-stress environments such as automotive or industrial components.
Dimensional Stability & Easy Processing
Low molding shrinkage (0.4–0.6%) and high viscosity prevent warping, while easy-release properties accelerate production cycles for complex parts like connectors or housings.
