Superior Design Flexibility
and Performance
Delrin® behaves more like metal than other unreinforced
plastics thanks to its very high crystallinity. It’s the first
choice for designers seeking:

A Problem-solver for Reliable,
Long-lasting Moving Parts
Delrin® offers one of the lowest coefficients of friction,
wear rates and noise when compared with other
polymers. With a wide range of internally lubricated
grades, Delrin delivers better acoustics, minimal wear and
superior friction performance so dynamic systems, like
robotic vacuum cleaners, can keep running with ease.

Assured Safety and Durability
in Food Contact
Delrin® food-contact-compliant grades meet industry
regulations.* For mechanical parts in food contact, Delrin
can survive repeated use in processing equipment
thanks to its superior strength and wear resistance.
Combined with low temperature toughness, Delrin can
also be used for components in ice making as well as
dispensing systems for cold drinks and ice cream.
Delrin resists stains and stands up to the harshest
cleaning agents, helping avoid premature failure from
aggressive chemical cleaning agents, including:
• 2.5% bleach solution
• Ethanol
• 3% peroxide solution
• Quaternary ammonium solution
• Clorox Healthcare®** Bleach Germicidal Cleaner
• Lysol®** Mold and Mildew Remover
• Sani-Cloth®** AF3 Germicidal Disposable Wipes
• Virex®** Tb Disinfectant Cleaner
When used with these cleaners, the tensile strength of
Delrin was greater than 80% retention after 96 hours of
exposure.

Combining strength and stiffness with
low moisture absorption, Delrin offers
robust and consistent performance for
food processing applications.
Compliant with FDA, EU10/2011 and GMP (EC) 2023/2006.

Contributing to Your
Sustainability Journey
Improved eco-profile. Identical properties.
Sustainability is a global driving force. Today’s product
developers are working to reduce or eliminate negative
environmental impacts through thoughtful selection of
materials and designs. By working with Delrin® Renewable
Attributed (RA), significant reductions in carbon footprint
are achievable without compromising on performance.
Tensile modulus
The base polymer for Delrin®
RA is produced using 100%
bio-feedstock from waste
in accordance with ISCC
mass balance certification.
All Delrin® RA products
are manufactured with
100% certified renewable
electricity and offer up to a
75% lower carbon footprint
versus fossil-based Delrin.

To reduce overall material usage, designers can take
advantage of the superior properties of Delrin to make
component sections thinner. Delrin also has the potential
(if and where infrastructure exists) to be 100% recycled to
support circularity initiatives.
