Decreasing the risk ​of fire in USB-C Connectors

USB-C connectors are becoming the consumer electronics industry’s most widely used data and power interface. As their usage grows, so do the risks of premature failures or fire hazards if manufacturers choose the wrong materials.

Modern consumer electronic devices, such as notebooks and docking stations, are designed to process more power faster. While standard USB 2.0 or 3.0 connectors process 10W of power, USB-C cables process 27W

The smaller pitch in USB-C connectors creates insulating walls between connector pins of only 0.2mm (thinner than those in previous generations). Thin-walled insulating materials need to demonstrate superior resistance to electrical tracking in high voltage environments to prevent potentially serious fire hazards. Consequently, tracking resistance of insulator plastic becomes key for product reliability.

Learn why Stanyl is trusted in USB-C connectors

Stanyl is a high-performance polyamide that provides best-in-class wear and friction properties, excellent processability with high flow, and superior mechanical strength in high temperature applications. The material offers:

  • High retention force between contacts and plastic housing
  • High stiffness, toughness and weldline strength
  • Up to 50% more wear resistance than competing high-temperature polyamides
  • High flow needed for 0.1mm wall thicknesses
  • Processing window that enables second insert molding
  • Lead-free reflow soldering without blistering

With a proven track record of success with more than 300 million USB-C connectors manufactured using Stanyl, DSM is a trusted material science partner for the world’s leading electronics manufacturers.

USB-C innovation insights

  • DSM and Samsung Electronics work together to develop a smartphone made with recycled ocean-bound fishing nets

    DSM partnered with Samsung, a leading company in the mobile industry, to develop innovative and eco-conscious technology. The incorporation of Akulon® RePurposed into Samsung’s latest flagship device, the Galaxy S22 series smartphone, Galaxy Tab S8 series tablet, and Galaxy Book2 Pro series PC, marks an incredible achievement and a milestone in both companies’ sustainability journeys.

  • Manufacturing safe and reliable fast-charging connectors for smart devices

    Fast-charging smart devices are increasingly important to consumers. USB-C connectors rapidly restore electronic battery life, yet these cables can create a fire hazard if manufacturers select low-performance insulating plastics. Learn about proven materials solutions that decrease safety risks and enable you to deliver high-performance fast-charging connectors with stringent design requirements.

  • Enhancing USB-C connector performance and reliability with Stanyl®

    Since USB-C connectors process power levels from 40 to 100 Watts, they’re also more susceptible to electrical tracking, which may lead to premature part failure, or eventually create a fire hazard. As a result, consumer electronics developers need assurance that connectors designed to charge their devices won’t need to be recalled or frequently replaced.
