Electronic & Electrical Connectors

Engineering Polymers for Electronic & Electrical Connectors

Electrical and electronic connectors form a vital link in the assembly, structure and operation of electrical and electronic systems. As a result, their performance and reliability is paramount.

DuPont offers a range of engineering polymers with grades developed specifically to address the demanding needs of the electrical and electronic industries.

Applications such as backplane, optical, SIM and PCB connectors can leverage the strong and extensive research and development efforts that DuPont has committed to its DuPont™ Zytel® and DuPont™ Crastin® engineering polymers. Indeed, desginers can in many cases use either of the materials depending upon the final application and the functional and environmental demands that it will face.

Connecting With The Right Material

DuPont ™ Zytel® is an incredibly versatile plastic, which is easy to process, easy to modify to meet specific needs, while being environmentally responsible in production and in reuse. It's tough, light and resilient in hot, chemically aggressive and humid environments.

Zytel® PA66 FR (flame retardant) is available in both halogenated and non-halogen versions; with the non-halogen version using a patented combination of flame-retardant copolymer and stabilizer to improve melt stability, flow and surface appearance and reduce mold deposit.

DuPont™ Zytel® HTN high-performance polyamide resin provides excellent flow and dimensional stability, to help make it possible and cost-efficient to produce thinner and lighter components for the latest generation of electrical and electronic devices.

Zytel® HTN offers the necessary performance characteristics to contain electronic connectors, relays, light-emitting diode components and various other electrical parts.

Zytel® HTN is also available in a halogen-free, flame-retardant grade in compliance with recycling programs for discarded electronic products. It can also withstand high-temperature circuit assembly methods, including those using lead-free solder.

DuPont™ Crastin® PBT thermoplastic polyester resins can be extensively modified to make the suitable for an enormous variety of electrical and electronic applications. Variants include flame retardant, glass-reinforced and hydrolysis resistant versions.

Crastin® PBT grades offer stiffness, toughness, heat resistance, friction and wear resistance, excellent surface finishes and good colorability. They have excellent electrical insulation characteristics, with high-arc-resistant grades being available.

DuPont is also working on renewably sourced variants of many of its engineering plastics helping electrical and electronic companies address stringent sustainability legislation. In addition DuPont is also constantly evolving its range of halogen-free products and is working on the development of halogen-free Crastin® in order to address the electrical and electronic industry's requirements.

Improved Processing Leads to Improved Connectors

In addition to the in-service performance of its engineering polymers, DuPont is also working on the processability of its many materials, giving designers greater flexibility and the chance to specify smaller parts, smaller production runs, higher tolerances and greater product variety all leading to a faster time to market and reduced costs.

DuPont's materials offer flexibility and features that appeal to all levels of the supply chain. Suppliers will appreciate the worldwide supply flexibility, while molders will appreciate the high productivity and reduced manufacturing costs. OEMs and end users can pass on the green credentials to their customers, while appreciating the superior functional characteristics of the entire DuPont range.
