Discover our ranges of food and non-food seals for tank doors and hatches.
The optimal use of the seal in service and its life span are very dependent on the storage conditions undergone by it before use. The ageing resistance of seals at static rest is very different between elastomers. </However, a storage life of two years is guaranteed for all seals provided that controlled storage conditions are respected (seals laid flat without tension, at room temperature, away from light, heat and bad weather, far from any source of ozone (anti-static bars, etc.).
These conditions apply to all types of elastomers. This information is based on reliable information provided by our suppliers and we cannot be held responsible in any way.

The chemical resistance of rubbers is strongly influenced either by the temperature of the liquid in contact, or by the duration of this contact, or finally, in the case of chemical solutions, by the concentration of the active product... The resistance values given here are for information purposes only and may be modified by the following determining factors: constitution of the rubber mix, varying temperatures, varying loads or elongation, atmospheric agents, duration of exposure, etc. *Viton® is a registered trademark of DuPont Performance Elastomers.
Opened in 2014, and the result of mature thinking and technical expertise, Boyer is proud to present its new joint manufacturing plant, for perfect waterproofing control!
Optimal quality and use of the seal in service and its service life are highly dependent on the storage conditions experienced by it prior to use.
The ageing resistance of seals at static rest also differs greatly between elastomers. However, a storage life of two years is guaranteed for all seals provided the following conditions are met:
These conditions remain valid for all elastomer types. This information is based on reliable information provided by our suppliers and in no case, engage our responsibility.
