Overview

Gore develops high performing products that meet or exceed the applicable environmental and safety standards in the regions where our products are sold. We are committed to innovation and seek continuous improvement in our products to meet the needs of our customers and end-users, and also to comply with the appropriate industry standards. We follow the developing science, do our own extensive internal testing and invest in independent research to produce and deliver products of high societal value in a manner that is environmentally responsible.

POLYTETRAFLUOROETHYLENE (PTFE)

Gore uses a fluoropolymer, PTFE at the heart of many of our products.

Fluoropolymers, like PTFE, are valuable materials with unique properties that enable high performing products across a range of industries and end uses. For more than 60 years, Gore has applied its deep understanding and expertise in working with PTFE to develop products of high societal value ranging from enabling technology for industrial filtration, to communication systems used onboard aircraft and in space exploration, to implantable medical devices that save and improve lives.

The chemical and physical properties of PTFE make it ideal for use in demanding applications — enabling it to withstand exposure to a wide range of corrosive substances and maintain its performance in extreme temperatures.

Understanding Per- and Poly Fluoroalkyl Substances (PFAS)

PFAS stands for Per- and Polyfluoroalkyl substances and describes a wide range of chemistries with very different properties and uses. Because there are clear and important distinctions between the more than 4,700 materials often referred to as PFAS, it is a very complex topic. Therefore, when communicating about PFAS, we believe it is important to be specific about the particular chemistries or type of PFAS being discussed. There are significant distinctions between the chemical and physical properties of fluoropolymers like PTFE and other materials most often associated with the term PFAS. PTFE does meet the very broad definition of the term despite the important distinctions. Often, agencies, regulators, scientists or media may use the acronym PFAS when the specific point being made is only accurate for certain PFAS, for example non-polymers such as PFOA. "PFAS" are, for example, described as mobile in the environment. PTFE, a fluoropolymer, is not mobile in the environment.

Publications

Gore scientists are active participants in the scientific community, lending their expertise, research and time to broaden the understanding of fluoropolymers. Gore scientists publish their research regularly in peer-reviewed scientific journals. They attend and contribute to scientific conferences worldwide. They also share their knowledge with regulatory bodies.

Here is a small sample of their work:

This paper provided an overview of fluorine-containing compounds, their uses, their toxicological, chemical, and physical properties in relation to environmental occurrence, their analysis, and how the interpretation of the analytical data is critical to effective regulation.

Critical Review of A Recommended Analytical and Classification Approach for Organic Fluorinated Compounds with an Emphasis on Per- and Polyfluoroalkyl Substances

The present paper brings together fluoropolymer toxicity data, human clinical data, and physical, chemical, thermal, and biological data for review and assessment to show that fluoropolymers satisfy widely accepted assessment criteria to be considered as “polymers of low concern” (PLC) and to show that fluoropolymers are distinctly different enough from other classes of PFAS to not be grouped with them for hazard assessment or regulatory purposes.

critical review of the application of polymer of low concern and regulatory criteria

A Society of Environmental Toxicology and Chemistry (SETAC) Focused Topic Meeting (FTM) on the environmental management of per- and polyfluoroalkyl substances (PFAS) convened during August 2019 in Durham, North Carolina (USA). Experts from around the globe were brought together to critically evaluate new and emerging information on PFAS including chemistry, fate, transport, exposure, and toxicity.

Executive Summary

Scientists, regulators, and concerned communities often fall into one of two groups: one says all PFAS should be banned and the other says PFAS are so different that each must be evaluated, classified, and regulated individually. Barbara J. Henry, PhD, a toxicologist with W. L. Gore & Associates, says there’s a middle way forward if PFAS are grouped by their properties.

An Approach to Risk Management

The new, peer-reviewed paper published in international scientific journal Chemosphere sought to build on previous studies by examining what happens to a PTFE polymer at the end of its life — when it’s thrown away and ends up in a municipal waste incinerator. The study subjected the polymer to the conditions of such an incinerator to determine whether PTFE would break down into PFAS of Environmental Concern.

Societal Value of Fluoromaterials

At Gore, we use material science to create products that improve life. In developing a product, we consider whether it will deliver value to society and/or solve a complex challenge. Here are some of the ways Gore products improve life:
