Delrin® 500CPE outperforms medium and high
molecular weight acetal copolymers
Delrin® 500CPE delivers superior performance compared to
competitive medium molecular weight (MMW) copolymers, as
well as competitive high molecular weight (HMW) copolymers.
Additionally, the Delrin technical team provides design, technical
and processing support to ensure production of high-quality,
high-performance parts.
Potential applications
Delrin® 500CPE is suitable for a wide range of applications
including but not limited to:
• Automotive components: fasteners, seatbelt components,
levers, brackets, switches and gears
• Sporting goods: buckles, latches and surface parts
Performance advantages
• Window hardware: clips and housings
• >10% higher tensile properties
• Irrigation components: automatic sprinklers and commercial
irrigation systems
• Impact resistance (>25% higher vs. MMW) 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 HDT (heat deflection temperature)
• Retention of all the other typical properties of Delrin:
- low wear and friction
- resiliency
- chemical and solvent resistance
- low-temperature toughness
Plus, Delrin® 500CPE offers low VOC emissions (below 2 ppm in
VDA 275).
