What is Crafter Blue strap made of?

Each Crafter Blue strap is made of vulcanized rubber. Vulcanized rubber is a material that undergoes a chemical process known as vulcanization. This process involves mixing natural rubber with additives such as sulfur and other curatives. Vulcanization makes rubber much stronger, more flexible, and more resistant to heat and other environmental conditions. Vulcanized rubber makes both soft and hard objects, ranging from rubber bands to bowling balls. In fact, almost any rubber object consists of vulcanized rubber. Vulcanized rubber is stronger than non-vulcanized rubber because its bonds are made of cross-links at an atomic level. This allows vulcanized rubber to stand up to more stress and damage. Vulcanized rubber is also more rigid than non-vulcanized rubber, so it is more stretch-resistant in the first place. However, vulcanized rubber has the same elasticity level as non-vulcanized rubber.
