The advantages for the products from Yamamoto

1. Warmer Material

The highly porous structure of limestone neoprene means that the material is filled with tiny air cells formed by closed cells. In fact, it has about 30% more air cells than other rubber materials. This has several advantages, including a warmer material. To match the warmth provided by the 2mm limestone neoprene sheets, 3mm oil-based neoprene sheets are required. The wearer can get more warmth from less stuff, and fewer raw materials are needed to do so.

2. Longer Lifespan

The tiny micropores in the oil-based neoprene are interconnected. In limestone-based neoprene, they are independent. The result is a more durable material that is less prone to tearing and is able to distribute pressure, stretch and stress across its structure. In short, neoprene wetsuits made from limestone tend to last longer. This results in better value for consumers, keeps wetsuits out of landfill for longer, and reduces the need to manufacture new neoprene.

3. Improved Impermeability

Neoprene absorbs some water, but the tiny air bubbles inside the material don’t. Since neoprene crafted from limestone has more air bubbles, it absorbs less water. That keeps wetsuits made from this material lighter and more comfortable.
All of the neoprene absorbs some water, but the tiny air cells inside the material can’t. As neoprene made from limestone has more air cells, then it absorbs less water. This lets wetsuits made from this material be lighter and more comfortable when using.

4. Reduced Environmental Impact

Mining limestone may take a toll on the environment, but it’s a smaller price than the one required for oil. Likewise, creating polychloroprene chips from limestone requires less energy than crafting them from oil products. Plus, Yamamoto takes care to choose eco-friendly methods of power generation.

As we know, mining limestone can be damaging to the environment as well, but its price is lower than what oil needs to be. Likewise, making polychloroprene chips from limestone requires less energy than making polychloroprene chips from petroleum products. In addition, Yamamoto carefully chooses environmentally friendly methods of generating electricity.

GREENER FUTURE

Finally, it's easy to make a convincing argument that neoprene made from limestone is more environmentally friendly than neoprene made from petroleum. However, claiming it is an environmentally friendly material is not really accurate. Fortunately for the planet and those who care about protecting it, the surf industry is still working hard to find neoprene that is truly eco-friendly.

There are more and more innovators, manufacturers and designers who are continuing to push the boundaries of green neoprene.

1. Jako neoprene from Korea, it has produced limestone material, its property is closed to Yamamoto neoprene more and more.

2. Neogreene, a material that reportedly uses 25 percent less electricity and 25 percent less petroleum than traditional neoprene, received a lot of attention when it was introduced in the 2000s. While the company behind it disappeared before the material hit the consumer market, the buzz it has caused shows that there is serious interest in environmentally friendly neoprene.

3. Meanwhile, the new developments continue to shape the next generation of wetsuits. Patagonia replaced neoprene wetsuits with wetsuits made from Yulex in 2010s. This product is made from natural rubber extracted from the hevea trees. While growing and harvesting rubber can cause serious damage to the environment, the materials used in Yulex come from growers who follow sustainable practices and protect ecological integrity and biodiversity. Others are working to develop new techniques and improve the adhesives and chemicals used in assembling and sealing wetsuits.
