Product Features and Performance
Ultra high heat deflection temperature ≥240 ℃ maintains structural stability under long duration high temperature service, resisting softening for heat dissipation related components.
Ultra high Barcol hardness ≥70 delivers outstanding wear and knock resistance; balanced mechanical properties resist cracking under thermal cycling conditions.
Low water absorption guarantees stable dimension under hot humid working environments.
Good flow ability enables molding of complex parts with cooling ribs, securing precise dimensional control.
Reliable electrical insulation with thermal barrier effect protects surrounding electronic components; UL94-HB for general heat dissipation equipment without V0 flame retardant requirement.
Supported by in house BMC production lines for stable bulk supply; formula adjustment available for heat resistant component projects.
Applications
Suitable for components requiring continuous heat resistance and heat dissipation structures: lamp heat sinks, motor thermal insulation housings, power supply heat dissipation brackets, heater insulation supports, industrial heating module casings, thermal insulation shells for home appliance heating units, inverter heat bases and other general heat dissipation & thermal insulation products.
