PFAS-Free surface treatments for O-Rings

octobre 03, 2025

Design, Research and Development / Design

In response to growing environmental concerns and evolving regulations, we have developed a range of PFAS-free surface treatments for seals. These solutions allow manufacturers to maintain high performance while eliminating harmful substances from their processes. Our treatments are not only eco-compliant, but they are also fully compatible with cleanliness requirements for seals: intermediate, standard, severe, and very severe.

Lubricoat A WB3-N: efficiency and versatility

Available in multiple colors (transparent, blue, orange, green, red, gray, violet), this dry varnish contains a PFAS-free lubricating agent. Compatible with AEM, EPDM, FKM, HNBR, and NBR compounds, it facilitates assembly, reduces friction, and optimizes seal distribution in automated systems.

Lubricoat KT: designed for mechanical stress

This PFAS-free dry varnish stands out for its durability under both static and dynamic conditions. It effectively reduces assembly forces and mechanical strain, especially in demanding applications such as valves.

Lubrifilm SF: the Latest PFAS-Free Innovation

Lubrifilm SF applies a synthetic polymer oil film to the surface of the seal, significantly lowering insertion forces and eliminating the risk of twisting or mechanical damage. Its adjustable dosing allows for fine-tuning between performance and speed in automated distribution systems. It remains effective even after long-term storage and is compatible with a wide range of compounds: FKM, FVMQ, NBR, HNBR, EPDM, ACM, and AEM.

Hutchinson plant in Château-Gontier achieves AeroExcellence Bronze level

mai 27, 2025

BACKLOG FUSION EXPO
After obtaining the EN 9100 aerospace certification in 2021, the Château-Gontier plant was evaluated according to the AeroExcellence framework launched by the French Aerospace Industries Association (Gifas). The AeroExcellence assessment is a mark of confidence for partners and customers, ensuring that processes meet the most stringent aerospace and defence requirements in terms of operational excellence, the environment and cybersecurity. This rigorous assessment took place from Tuesday 22 to Thursday 24 April 2025 and focused on organisational and resource management, planning and logistics, supplier management, industrialisation and quality, and production excellence. "We are very proud to have reached the Bronze level in the AeroExcellence evaluation. This result reflects the dedication and hard work of the teams to achieve excellence in all aspects of our business. We will continue to innovate and improve our processes to contribute to a high level of excellence in the Aeronautics sector and to meet the expectations of our customers and partners." said Ludovic Duval-Arnould, Industry Sales Manager at Hutchinson.

Hutchinson has developed a fire EPDM compliant with the UL94, V-0 standard for sealing battery packs

mai 05, 2025

Fireproof material
With the development of e-mobility, battery safety is a major issue for carmakers.  Teams from the Precision Sealing Systems business and the Research and Innovation Centre have developed a new material that meets the requirements of the UL94, V-0 standard, which is the most stringent level of fire resistance.  Moreover, this EPDM has the advantage of containing no halogens, making it not only safer but also more durable than other materials on the market.  Thanks to our formulation expertise, this material guarantees optimum sealing, good chemical compatibility and good resistance to low temperatures. Its blue colour makes it easy to identify in its environment. This new EPDM is designed for battery pack gaskets and seals for the battery pack cooling circuit, to protect the cells in the event of contact with the coolant or the spread of flames. It can also be used for electric motor cooling applications and battery peripheral equipment.  Thanks to its properties, this material is also a promising choice for demanding industrial and aeronautical applications. Hutchinson is confirming its know-how and its commitment to making mobility safer and more sustainable.

NVH encapsulation solution for Electric vehicles

octobre 07, 2024

Hammer mill

Hutchinson has designed an innovative solution attenuating the sound vibrations emitted by E-compressors and E-Motors.

Our multi-material solution offers an excellent combination of vibration attenuation and absorption, especially in high frequencies (>1000 Hz) which is the range of E-Modules concerned.

Our Acoustic cover is thermoformed, lightweight and made of recyclable materials. It can provide rapid prototype solutions.

Numerical simulations and specific acoustic tests enable us to answer accurately to customers’ specific requirements.

Thanks to our material expertise, we improve E-compressor efficiency and the active cooling systems for E-motors with optimal thermal insulation properties.

This acoustic encapsulation solution has been validated and selected in 2023 by a major international OEM.
