Application

  • Extrusion: Heavy-duty profiles, electrical conduits, and industrial tubing requiring rigidity.
  • Injection Molding – Electrical: Connectors, circuit breakers (leveraging CTI 175).
  • Injection Molding – Automotive: Under-hood components, sensor housings (heat/impact resistant).
  • Injection Molding – Industrial: Gears, pump housings, and enclosures demanding dimensional stability.

Features & Benefits

Unmatched Impact Resistance

With Charpy impact strength of 600 kJ/m² (23°C), Makrolon 8325 withstands heavy shocks, reducing part failure in high-stress environments like automotive components.

Superior Thermal Stability

Deflection temperature of 142°C (1.8 MPa) and VICAT 150°C ensure reliability in high-heat applications, such as electrical housings near heat sources.

Precision Dimensional Control

Low shrinkage (0.35% parallel) and 20% glass fiber reinforcement guarantee tight tolerances for complex industrial parts, minimizing post-processing.
