Combining the industry standard properties of a Delrin® 300CP
with state-of-the-art low emission technology
General information
Delrin® 300CPE is a medium-high viscosity low emission grade
acetal resin family and is part of the low-emission CPE group.
Excellent balance of properties
When all these benefits are considered, designing with Delrin®
300CPE will lead to lower cost per part.
Additionally, the Delrin technical team provides design, technical
and processing support to ensure production of high-quality,
high-performance parts.

Delrin® 300CPE outperforms high molecular weight acetal copolymers
Delrin® 300CPE delivers superior performance compared to competitive high molecular weight (HMW) copolymers.
Performance advantages
Properties
• Higher tensile properties (>10% vs. HMW)
Tensile modulus
• Impact resistance (40% 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
