Because of these risks, regulatory bodies worldwide are working to restrict or ban the use of PFAS in certain products and to establish safe levels of exposure.
Crocs: The Material Composition
Crocs are primarily made from a proprietary closed-cell resin material called Croslite. Croslite is a cellular resin, not rubber or plastic, and it is a key element in the comfort and design of Crocs. The exact chemical composition of Croslite is often proprietary information, but it is known to be a type of expanded resin. The manufacturing process involves injecting the resin into molds, which creates the distinctive shape and comfortable feel of Crocs footwear. Understanding the composition of Croslite is crucial to assessing whether PFAS might be present.
The manufacturing process for Crocs involves several steps. The Croslite resin is first produced, then injected into molds. The molds shape the clogs, and the final product undergoes quality control checks. The exact formulation of Croslite can vary slightly depending on the specific model and manufacturing location. This variation means the potential for PFAS presence may not be uniform across all Crocs products. The company has stated its commitment to responsible manufacturing, and its material sourcing is an important factor in this process.
