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.
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:
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.
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.
Manufacturers are increasing charging speeds of smartphones, laptops and tablets. When fast charging devices have a charging standard of more than 18 Watts, they are charged much quicker and the cables and connectors used must be able to handle the higher voltage and be compatible with the device’s and charger’s fast charging standard. Connector manufacturers need to select insulating materials specifically developed to minimize the risk of fires that can potentially lead to serious accidents, costly recalls and severe damage to the brand’s reputation.
The USB-C connector outperforms traditional cable performance and is convenient—you can flip the connector to both sides, making it much easier to use. Plus, one standard means less cables will be produced, ultimately reducing e-waste overall.
