The food industry secret: Delrin®
Delrin is a tough, lightweight, durable, wear-resistant, low friction, low noise and
®
high performance acetal resin solution for modern conveyor systems. It offers enhan-
ced quality and performance, uncompromising reliability and greater design freedom
than metal or other plastic solutions. Bottling conveyor chains and belts of Delrin
®
need less maintenance than chains and belts of other materials.
With a lower overall system cost, less energy consumption and longer service life,
conveyor chains using Delrin components remain clean, safe and more hygienic versus
®
metal alternatives. Contact us to learn how Delrin can streamline your operation and
®
save you money.

The problem with metal
> The Challenge

> Why DuPont
Traditionally, metal has been used for conveyor belts because of its strength. However,
Get in touch by phone*: metal is not without its problems. Working environments are noisy. Metal must be
lubricated often, and even despite this, parts wear down due to frequent friction.
Tel. 0800 – 367 668 38 Metal must also cleaned with a special soap and a lot of water, which is not very
http://dupont.com/food-contact environmentally friendly and slows production.

Delrin®: The plastic alternative to metal

DuPont not only provides different grades of Delrin with internal and external

with other substrates to make it x-ray detectable.

Advantages include:
- Production flexibility: The injection molding process used for components of Delrin
®
is much simpler and more cost effective than the manufacture of steel chains.
- Low friction: in most applications, conveyors can run smoothly with reduced soap
and water lubrication or even without lubrication at all.
- Improved productivity due to lower maintenance: Delrin conveyor systems need less
®
maintenance and are subjected to fewer downtimes.
- Less tipping, wear, noise: Low friction reduces the risk of product tipping, cuts
conveyor component wear and holds down noise.
- Permanent lubricity: The lubricant is added with Delrin during the compounding
®
process.
- Durability: With the superior fatigue strength of Delrin , the chains withstand repeated
®
„jerk loads“ produced when conveyors start with product already on the line.
- Resists harsh chemicals: Delrin is resistant to typical cleaning solutions and other
®
agents used to wash down conveyor lines.
- Modular design makes optimized plant layouts possible; conveyor sizes can be
designed to match precise line capacity specifications.
- Environmentally friendly with low or no water usage and elimination of soap typically
used with metal.

Delrin the backbone of success
Get in touch by phone*:
The use of DuPont acetal resin helped Flexlink to develop a generic conveyor chain

and can be quickly and easily assembled using ordinary hand tools. The conveyor
systems are also lighter and therefore cheaper to transport and mount than metal
chains.
