Entropy Resins is now listed with the USDA as a ‘BioPreferred’ product. This label provides government certification of manufacturers claims of using biological content in their product. This is a significant step for a resin, since the vast majority of resin is made entirely from petrochemical sources. Not only has Entropy innovated a new type of eco-friendly resin, they have spent the money to have it analyzed and certified as such by 3rd Party Verifiers. They are ‘walking the talk’ like no other surfboard manufacturer (so far…).
