Application

  • Electrical Enclosures: Flame-retardant housings for switches, connectors, and control units.
  • Automotive Components: Engine bay parts, sensors, and structural supports requiring heat/impact resistance.
  • Industrial Equipment: Gears, housings, and machine components needing dimensional stability.
  • Consumer Electronics: Opaque casings for power tools or appliances with strict safety standards.

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.
