Delrin 300CPE

General Information

DuPont™ Delrin® 300CPE is a new medium-high viscosity lowemission grade in its acetal resin family, part of the low-emission CPE group.

Excellent Balance of Properties

• Tensile modulus (stiff without the use of fibers)

• Yield Strength

• Impact Strength (including low temperatures)

• Creep resistance

• Fatigue resistance

Without compromising performance, the new

DuPont™ Delrin® 300CPE adds:

• Low emission (below 2 ppm in VDA 275)

Performance Advantages

• Higher tensile properties (>10% vs. HMW)

• Impact resistance (45% higher vs. HMW) over a large

temperature range

• Significantly better flow, which permits:

- better fill of thinner-wall cavities

- more effective design of thin-wall parts

• Superior fatigue resistance

• Higher heat deflection temperature

• Retention of all the other typical properties of Delrin®: low wear and friction, resiliency, chemical and solvent resistance,low-temperature toughness and more

Plus, Delrin® 300CPE offers low VOC emissions (below 2 ppm in VDA 275).

Customer Benefits

• Greater design flexibility to use lower wall thicknesses

through easier tool filling

• Ability to make durable parts at possibly higher

production rates (faster molding cycle time)

• Greater safety factor in impact resistance

• Higher part performance and reliability

• Consistent part performance over wide operating temperature range

When all these benefits are taken into account, designing with Delrin® 300CPE will lead to lower cost per part.

DuPont™ Delrin® design, technical, and processing support to ensure production of a high quality part that delivers on its promise.

Potential applications

A wide range of potential applications including:

• Automotive components: fasteners, seatbelt components, levers, brackets, switches, gears

• Sporting goods: buckles, latches, surface parts

• Window hardware: clips, housings

• Irrigation components: automatic sprinklers, commercial irrigation systems
