Neoprene is a “TRUE” Compressed Neoprene. Many of the “COMPRESSED” Neoprene materials and Dry Suits that are currently being offered on the market, are in fact made with HIGH DENSITY Neoprenes, which are not Compressed. They are merely stiffer more solid neoprene rubber compounds, which contain less amounts of Nitrogen Gas Cells, and therefore provide less Thermal Insulation.
YAMAMOTO HYPER-COMPRESSED is produced by expanding a Master Slab of regular dive grade Neoprene with ‘Nitrogen Gas Closed Cells’ up to 30mm thickness, and then COMPRESSING it in a heated pressure press back down to 15mm thickness. We then split the resulting Compressed Master Slab to the client’s desired thicknesses. These split thicknesses in effect have double their thickness factor amount of thermal insulation.
YAMAMOTO’s production method creates a true Compressed Neoprene which has an excellent compression resistance and memory/recovery, and at depths of around 40 meters a diver can really notice the difference in WARMTH & THERMAL PROTECTION, where other ordinary High Density Neoprenes are basically COLD ! HYPER-COMPRESSED is available in all thicknesses 2mm, 2.5mm, 3mm,3.5mm 4mm, 4.5mm, 5mm, etc, to clients preference.
HYPER-COMPRESSED can be lined with standard NYLON, or many of our specialized heavy duty fabrics, such as KANOKO 505, TECHNO 500, SPANDURA 800, all of which can be treated with our special PU Resin High Abrasion Resistant Coating CORALTEX I!, or lined using Yamamoto’s superior TITANIUM ALPHA thermal coating.
As a result of a series of diastrophism over a vast span of time beginning approximately 80 million years ago. a rock situated in the present-day Hawaiian Islands traveled a long way to Mt. Kurohime in Niigata. Prefecture, Japan. It was us, YAMAMOTO CORPORATION, who first shed light on this unique rock. Charmed by its mysteriousness, we have continued to create novel, business enterprises. Being composed of 99.7% calcium carbonate, this rock is miraculously free from almost all impurities. Using this rock as a starting material, we have developed a number of high-quality materials that have found applications in various fields such as; sports gear, medicine and fashion. Many of these have lead to the revolutionary new use of materials in these fields. Now, we have inspired yet another life into these rubber materials. In the evolution from technical rubber to Bio Rubber materials, our novel scope of activities has just begun.
We have been emphasising with our pride that YAMAMOTO Neoprene is not petrochemicals but is from Limestone base polymer with 99.7% calcium carbonate and this point also is emphasised for greater acceptance in the market of the medical products made of our neoprene rubber. It is not true that calcium carbonate foam is not as clean and environmentally friendly even from the point of its manufacturing process. We don’t use at all the petroleum as the important resource. The quantity of heat for processing and producing our raw materials is merely one tenth of that being used for refining the petroleum and the used heat is used for the nursery of eels. The source of heat is from the used tires and the electric power is generated from the several dams and power stations constructed downward the high mountain range. This special technology to convert the limestone to the rubber is to be really environmentally clean and friendly.
In addition, as we informed, our YAMAMOTO Neoprene material is not petrochemicals but are from Limestone based on 99.7% calcium carbonate produced in the mountain for the cement materials. It reserve is estimated possibly available enough for next 3,000 years. Throughout the processing and production, only the hydro-electricity is employed, free from environmental pollution. The waste heat is made use for the nursery of eels.
The material can be processed, to its low viscosity at low temperature. It is precisely controlled at below 0.5 Centigrade. Special compound to match limestone.
The brief processing method of the limestone is to make acetylene gas spring up by burning the tire and to liquefy it by the chemical polymerisation, then to dry it to chips.
Japanese special technology to convert the limestone to the rubber is to protect the Earth environment.
This new- wet & dry suit material which consists of a five(5)-later structure, neoprene rubber coated with Titanium Alloy and then laminated with synthetic fiber jerseys. As illustrated, the Titanium Alloy is a super thin film which provides effective heat retaining and heat retaining properties. In fact, a double lined material with Titanium Alloy will be 40% warmer than regular neoprene’s. The stretchability, feeling and wear comfort remains the same as conventional materials. This makes it possible to use a reduced thickness of neoprene, for instance 3.0mm in lieu of 5.0mm, obtaining the same thermal protection. Thickness and weight reduced by 40% retains the same warmth. Because of its lower buoyancy, divers do not have to use so many weights and rivers with more safety. It is now possible to make sure of a lighter weight, with more comfort and ease of movement, providing the user with less fatigue and comfort. “This Hi-Tec composite material leads the way in this new century.
