Here's a breakdown:
* Polychloroprene (Neoprene): This is a type of synthetic rubber that offers good resistance to chemicals, heat, and ozone. It's often used in applications requiring durability and flexibility.
* Polyurethane: This is a versatile plastic known for its strength, elasticity, and ability to be molded into various shapes. It's widely used in applications like foams, coatings, and adhesives.
Both materials offer the benefits of being impermeable, non-reactive with wine, and resistant to degradation. This ensures that the cork maintains its integrity and doesn't impart any off-flavors to the wine.
While synthetic corks are gaining popularity, traditional cork stoppers still dominate the market due to their established reputation and perceived quality.
