Food contact elastomers

Food contact elastomers are used as part of sealing solutions in food and dairy process and production environments, and in potable water systems.

These materials deliver exceptional sealing performance and long-term reliability. Critically, they also ensure the safety of end consumers is not compromised.

About food safe seals

Sealing materials used in food contact applications need to be both fit for their intended use, and not pose any health risk to the consumable product.

This means that food contact elastomers must be resistant to degradation from not only the process media, but also aggressive chemicals and temperatures typical of industrial cleaning regimes (CIP and SIP).

These materials can demonstrate they are fit for purpose through compliance with key industry and geography specific bodies.

PPE has also pioneered the development of Detectaseal®, a range of metal-detectable elastomers safeguarding against contamination events.

Food grade O-rings

PPE offers a range of food contact O-rings in elastomer materials compliant with the aforementioned standards.
