EPX 82

EPX 82 is a robust, epoxy-based engineering material that combines high strength, long-term durability, and functional toughness.

Material Overview

EPX 82 offers outstanding performance in demanding applications. Its heat deflection temperature ranges from 104°C to 130°C (depending on conditioning), making it ideal for automotive and industrial parts requiring high-temperature resistance, stiffness, and impact strength. For enhanced performance, baking EPX 82 in an inert oven significantly improves its toughness and impact strength without sacrificing other key metrics.

Key Features:

  • High Strength and Stiffness: Delivers robust mechanical properties similar to glass-filled thermoplastics, providing durability in demanding applications.
  • Temperature Resistance: Withstands temperatures up to 130°C, ideal for parts exposed to high heat in automotive and industrial settings.
  • Functional Toughness: Engineered to endure impact and mechanical stress, offering resilience for parts that undergo regular handling and wear.
  • Enhanced Toughness with Heat Treatment: Heat treatment in an inert oven improves functional toughness and impact strength, ensuring even greater durability.

DLS Technology

Digital Light Synthesis™ or DLS, is an innovative breakthrough in 3D printing using digital light projection together with oxygen permeable optics developed through Carbon’s CLIP™(Continuous Liquid Interface Production) technology.

Applications

Durable, Tough, and Precise Parts

  • Connectors: Designed for toughness, chemical resistance, and accuracy, EPX 82 is well-suited for durable, precise connectors in automotive and industrial equipment.
  • Brackets: Perfect for structural brackets that need to endure mechanical stress and high temperatures while maintaining dimensional accuracy.
  • Housings: Ideal for consumer-facing and industrial housings, where toughness, heat resistance, and a smooth surface finish are essential for aesthetics and performance.

Advantages:

  • Long-Term Durability: Retains mechanical and thermal properties over time, ensuring parts maintain their integrity and performance.
  • High Heat Tolerance: Capable of withstanding temperatures up to 130°C, making it reliable for high-heat applications.
  • Superior Toughness and Strength: Offers excellent resistance to impact and stress, ideal for structural and functional components.
  • Smooth Surface Finish: Provides a high-quality finish that requires minimal post-processing, suitable for consumer-facing parts.

Disadvantages:

  • Heat Treatment Required for Optimal Toughness: While EPX 82 performs well without treatment, baking it in an inert oven enhances its toughness, adding a processing step.
  • Specialized Equipment Required: Compatible primarily with Carbon’s DLS technology, which may limit accessibility for some users.
  • Limited Color Options: Available primarily in black, which may restrict design flexibility for applications needing color variety.
