The Material World of Crocs: Croslite Explained
The primary material in Crocs is Croslite, a closed-cell resin. This is the secret ingredient behind the shoes’ signature comfort and lightweight feel. But what exactly is Croslite? It’s not rubber or plastic, despite how it might appear. Croslite is a proprietary material, meaning it’s a unique formulation developed by Crocs. It’s often referred to as a ‘foam resin’.
What Is Croslite Made of?
Croslite is a polymer made from a mixture of petroleum-based materials. The exact composition is a closely guarded secret, but we can break it down into its key components. These typically include:
- Ethylene-vinyl acetate (EVA): This is a type of plastic that’s known for its flexibility, durability, and resistance to cracking. EVA is commonly used in shoe soles and other foam products.
- Additives: These are the ingredients that give Croslite its unique properties. They may include pigments for color, blowing agents to create the foam structure, and other compounds to enhance durability and performance.
The manufacturing process involves mixing these components and then expanding them to create the foam structure. This is what gives Crocs their distinctive look and feel. The exact formulation can vary depending on the specific Crocs product and the manufacturing location.
