Nineplus & Yamamoto Neoprene

Nineplus Wetsuits are made using Yamamoto’ closed cell foams and are all produced from 100% CR – Chloroprene Rubber. This is commonly known by most as Neoprene which is a DuPont trademark.

Nineplus wetsuits exclusively use Yamamoto rubber which is derived from Limestone and is over 99.7% calcium carbonate compared to petroleum based neoprene manufactured by other companies. Our neoprene is as environmentally friendly as possible. Not just in its makeup but mostly in the production technique which is the most damaging aspect of neoprene production. Yamamoto is the only rubber accepted into the medical profession and this is due to the environmental aspects of its production. Using calcium carbonate foam is much cleaner and more eco-friendly because it does not use petroleum as the important resource, instead it uses used car tyres. The heat used for processing and producing the raw materials is 1/10th of that being used for refining the petroleum based equivalent neoprene which most use. Furthermore the generated heat which is used in the neoprene production is then used to nurse eels, a major source of food within Japan. The source of the heat used in the factory is from burning used tyres within a controlled environment made possible using electricity derived from water turbines powered from the mountain streams. The way Yamamoto covert the limestone to neoprene is considered the most environmentally clean route in relation to how the product is generally made.

Yamamoto neoprene is not derived from petrochemicals in anyway, it is from limestone taken from the mountains within Japan in the same way concrete is made. There is estimated to be enough reserves to last another 3000 years so it is not a limited supply resource. By utilizing hydroelectric power the greenhouse gases are kept to an absolute minimum and by recycling the heat for farming the production process is as conservative as possible.

During processing a special compound is used to match the neoprene and it is processed at 0.5 centigrade. This process causes the limestone to make an acetylene gas which then by polymerization liquefies to the burnt rubber and then dry’s into rubber chips. Essentially car tyres are being recycled and bonded to limestone to create the neoprene sheets which are then cut and sewn into our wetsuits.

Nineplus & HASU use Yamamoto which assures;

Uniform cell structure

Highest Heat Insulation & Warmth

Lightweight & the lowest water absorption possible

Super low modulus stretch with optimum cell recovery – in regular terms you can stretch Yamamoto to its maximum over 2000 times and it will not bag out. Other neoprene has around 300 times and it loses it stretch. Worth noting next time the suit feels great for 6 months and then loosens on the elbows and the knees.
