High performance plastics for thin and reliable USB-C connectors

Thinnovation is the design challenge in mobile. On average smart phones become 12% thinner every year, resulting in connector designs like USB Type-C. With USB Type-C connectors being so small, the performance properties of the materials used for their housings are especially critical. Reliability is a key requirement, so the industry is looking for a plastic that has the magic combination: tough, reliable, rigid and with high flow.
USB Type-C connectors with high performance plastics

Approved by global connector producers 

Stanyl® and ForTii® and ForTii Eco have been approved by global producers for use in USB Type-C connectors. DSM’s materials answer the need for improved levels of safety and reliability.

Stanyl, ForTii and ForTii Eco have high CTI (Comparative Tracking Index) ratings well above 400V, which are a measure of their ability to provide electrical insulation. Alternative materials show a short break during CTI testing, resulting in a serious performance and safety issue for the complete device when in use and exposed to particles, moisture, sweat or other pollution due to electrical tracking. DSM high performance polyamides offer an ideal balance of toughness and stiffness. Furthermore, the flame retardant additive systems that they incorporate to provide a UL 94 V-0 rating contain no halogens.

Super thin

USB Type-C receptacle walls are 25% of the previous generation. For the plug they are even thinner at 0.12 mm. The excellent processability of Stanyl, ForTii and ForTii Eco provides connector designers with flexibility in component structure and tooling design. Stanyl, ForTii and ForTii Eco can be used to produce connectors with wall thicknesses as thin as 0.12 mm and which still have the required high mechanical properties. Their high flow in combination with high weld-line strength ensure the required high pin pull-out strength.

So is now the right time for you to Make Magic with plastics?
