PFAS - Information guide from MicroCare

Understanding PFAS and Their Growing Global Impact

Per- and polyfluoroalkyl substances (PFAS) are a diverse group of thousands of fluorinated chemicals used in a wide range of industrial applications. Their distinctive properties make them valuable in many processes, but concerns surrounding certain legacy substances have led to increased environmental scrutiny and evolving regulations worldwide.

It is important to recognise that PFAS encompass a broad range of chemistries, each with different characteristics, uses and potential risks. Understanding these differences is key to making informed decisions about regulation, product development and industrial applications.

Why Fluorinated Chemistry Matters

Fluorinated materials play an important role in industries where dependable performance, safety and precision are essential. From electronics and aerospace to automotive, medical devices and industrial manufacturing, these chemistries can offer properties that are challenging to achieve with other materials.

Key benefits may include:

• Resistance to heat and chemical exposure

• Non-flammable properties

• Low toxicity in specific formulations

• Distinct thermal, electrical and physical characteristics

• Suitability for use with sensitive components and materials

When appropriately selected and applied, these properties can support workplace safety, protect equipment and maintain consistent process quality.

Taking an Informed Approach to PFAS

MicroCare, believes PFAS should be assessed using sound scientific evidence and a clear understanding of individual substances and their applications. A blanket approach may overlook important differences in environmental behaviour, safety and technical function.

Evaluations should consider the distinctions between legacy PFAS with known persistence and bioaccumulation concerns, newer fluorinated chemistries, and specialised applications where suitable alternatives may not yet be available.

Regulatory decisions must consider environmental protection alongside the practical requirements of industries that depend on reliable, high-performance materials.

Responsible Chemistry at MicroCare

MicroCare is committed to managing chemicals responsibly and maintaining transparency with customers and regulators. We track changing PFAS requirements across the US, Europe and other international markets to support ongoing product compliance.

Priorities include:

• Meeting applicable regulatory requirements

• Supporting worker and end-user safety

• Maintaining product performance and process reliability

• Reducing environmental impact where feasible

We select fluorinated ingredients based on their functional value, particularly in applications where alternative technologies may not provide equivalent results.

Ongoing Review and Product Innovation

As scientific knowledge and regulations develop, MicroCare continues to review emerging research, supplier information and proposed legislation. This ongoing assessment helps guide product development and responsible material selection.

MicroCare does not use legacy bioaccumulative PFAS substances such as PFOA and PFOS. We also investigate reformulation and substitution opportunities when technically suitable alternatives are available. For customers pursuing specific compliance or sustainability objectives, PFAS-free products are offered where application requirements permit.

Commitment to Responsible Chemistry

Advanced chemical technologies remain important to progress across manufacturing, electronics, transportation and other essential sectors. Their use must be supported by careful evaluation, responsible management and continuous improvement.

MicroCare remains focused on:

• Meeting global PFAS compliance requirements

• Promoting responsible chemical management

• Maintaining open communication with customers and regulators

• Exploring safer, technically effective alternatives

The best path forward combines robust scientific assessment, environmental responsibility and a practical understanding of modern industrial needs.
