Rubatex G-231 Nitrogen Blown Neoprene

RubatexG-231 nitrogen blown neoprene is recognized as the world’s finest closed cell wet suit neoprene. The serious sport diver, professional divers, and especially the deep-water technical diver seek the features of G-231. This nitrogen blown neoprene is only made by the Rubatex Corporation and is referred to as G-231-N or G-231 for short. Rubatex G-231 is extruded in sheets up to approximately 1/2 inch thick. The sheet is then placed in a chamber in which pure nitrogen is injected under extremely high pressure to form nitrogen cells. This process creates very small consistent cells with a thick cell wall. The thicker the cell wall the more pressure the cell can withstand without losing nitrogen gas. The small consistent cell structure also creates a much more dense neoprene.

Rubatex G-231 retains 100% of its thickness based on samples compressed 50% of original thickness for 25,000 cycles with a 24-hour recovery period to simulate continual use and abuse. The lower the thickness loss, the greater the retention of insulation. G-231 is the only neoprene that can be dove in excess of 150 feet and to depths of more than 300 feet without experiencing a collapse of the neoprene. Our experience with G-231 nitrogen blown wet suits has proven its outstanding comfort, warmth and durability. We have professional divers that wear G-231 wet suits every day, 4 to 6 hours per day and only replace their suits every three to four years with proper care.

Visual Characteristics

Examining a cross section or raw edge of the material easily identifies Rubatex
G-231 nitrogen blown neoprene. The cross section will have a very fine porous cell structure.

A G-231 wet suit will also be noticeably heavier in weight than all other wet suits due to the density of the neoprene. Remember, the smaller the nitrogen cell, the thicker the cell wall, therefore the more pressure the cell wall can withstand without losing nitrogen gas.
