The DuPont Washington Works site manufactures hundreds of products specifically for the automotive industry.  Some of the trademark products produced at Washington Works include Delrin®, Crastin®, Rynite®, Zytel®, Butacite®, Dymetrol®, Hytrel® and Teflon®.

If you unbuckled your seatbelt today, you likely pushed a red button made from Delrin®, a tough, stiff polymer valued for its consistency in properties over a broad temperature range. Delrin® is also used in other interior applications such as the grille on the sound system speakers, seatbelt post loop (helps the seatbelt glide in and out), switch buttons on instrument panels, gears on electrical motors such as window lift, windshield wiper and seat adjustment motors.  Delrin® is also used for automotive upholstery attachment clips.  It also has exterior uses such fuel tank lids, fuel pump flanges and door handles.

Crastin® is a polymer that is easily molded, high performing and competitively priced.  Its use includes the decorative automotive applications such as interior trim.  For example, overhead lights in your car may have trim manufactured at Washington Works from Crastin®.

Rynite® is a thermoplastic resin valued for its high heat resistance.  It has tremendous “under the hood” applications such as fuse box covers and headlamp components.

Zytel® products are also used under the hood in air intake manifolds, heat exchangers, radiators and clips.  Wires ties on hoses and cable ties on headlamps are also made from Zytel®.  Zytel® is also used in car-top carrier racks.

Butacite® is an invisible material that adds a high degree of safety to a vehicle.  It is the polymer that is placed between two sheets of glass used in automotive windshields.   It will hold glass together on impact reducing shattering – thus keeping the individuals in the car in the event of an accident.

The same place where fishing line and paint brush filament is manufactured at DuPont Washington Works is also home to Dymetrol® -- a material that replaces springs in vehicle seating.  Since Dymetrol® weighs less than the steel in springs, it increases fuel efficiency.

Hytrel® is a polymer material used for CVJ boots on front wheel drive cars.  DuPont has nearly 100% of the market for this specialty material.

Most people know about Teflon® and its uses in house wares but there are at least 51 automotive uses for Teflon® manufactured in the fluoropolymers area of the DuPont Washington Works site. You can find products made at Washington Works in the fuel system, powertrain, electrical system, interior, brake system and chassis.  Oh, and yes, the same material used to create the stain protection in carpeting also provides superior protection to automotive interior fabric.
