Declaration of conformity and approvals

Food safety, PFAS and technical standards

Do the materials in your products need to be approved for food contact or meet other technical standards?

As a partner to companies and manufacturers in many different industries, we offer materials that:

  • suitable for contact with food or drinking water
  • are suitable for oils, acids or alkaline media
  • Suitable for low or high operating temperatures
  • can withstand harsh environments and aggressive influences
  • meet relevant fire classifications

Our specialists know the requirements and standards for your industry. Therefore, Betech can always help you with a solution that meets these requirements.

About PFAS - substances of eternity

We receive questions from customers about whether products in our portfolio contain PFAS and how we see the future of this area. Below is the current situation and how Betech is addressing the PFAS issue.

PFAS in gaskets, seals and other polymeric products

What are PFAS?

PFAS (per- and polyfluorinated alkyl substances) include thousands of man-made chemicals that are widely used in consumer and industrial products, including non-stick cookware, stain-resistant textiles, seals, self-lubricating bearings and many, many others.

The PFAS category includes fluoropolymers such as PTFE, PVDF, PFA FEP, FKM, FVMQ and FFKM. PFAS substances occur in various forms, including gases, liquids and solids.

PFAS are considered carcinogenic. They are easily dispersed when released into the environment and are non-degradable. This is why they are also known as persistent substances.

Developments in the PFAS area

This knowledge about PFAS substances has led to concerns and initiatives to regulate the use of PFAS.

In the producer market, for example, Solvay Specialty Polymers will discontinue its Hyflon perfluoropolymers and Algoflon® PTFE materials made using fluorouractives, and 3M will exit PFAS production and stop using PFAS across its portfolio by 2025.

Together with four other countries, Denmark has submitted a proposal for a total ban on the use of PFAS and the EU has published its REACH Annex XV proposal to restrict and phase out all PFAS substances.

Are there PFAS in Betech products?

The PFAS category includes fluoropolymers which are differentiated by the strength of their fluorocarbon bonds. Fluoropolymers are extremely long-chain molecules. Some examples are FKM (Viton®), FEPM (Aflas®), PTFE (Teflon) and PFA (Teflon, Hyflon®).

The use of fluoropolymers is widespread due to their unique properties such as high temperature resistance, chemical resistance and low friction. These properties make them useful in demanding applications such as aerospace, automotive, pharmaceutical, energy and process, semiconductor and electronics products.

Only a small part of Betech's product portfolio includes the aforementioned fluoropolymer materials.

Concerns and risks seem to be related to the production of the raw material (phase 1) and not least during waste management (phase 3), where a possible incineration of the products can release PFASs. During the use of the products (phase 2) - after production and before waste management - the items Betech sells (mainly gaskets and sealing elements) are very stable and do not release PFAS.

What do we expect to happen with PFAS?

Regulatory action as a result of the EU proposal is likely to affect the use and availability of fluoropolymers. It is expected that many fluoropolymer manufacturers will change their material compositions or abandon specific markets altogether.

At the moment, there are no good alternatives with properties similar to those of materials with PFAS compounds, but intensive research and development is underway.

How will we support you?

At Betech, we are committed to working with both our customers and suppliers to mitigate supply issues and prepare for the challenges ahead. We follow government regulations and engage in close dialog with the polymer industry to best support our customers in the transition to more sustainable materials.

Smiley - food control

Betech stores and handles materials that may come into contact with food in end-user applications. Therefore, Betech is subject to the Danish Veterinary and Food Administration's "Smiley" control scheme.

See food inspection results and Betech's last four inspection reports.

Data sheet and declaration of conformity

Do you need a Material Data Sheet or an EU Declaration of Conformity?

At Betech, you get documentation of the product or material's properties and that it meets the relevant standards and approvals.

Contact us via the form here and provide the identification of the material in question - we'll make sure you get the necessary documentation quickly.
