Benefits of technology

This patented technology involves combining different types of polymers together with specific ingredients like chlorosilanes or acetylenes sulfur chemistry into an elastomeric compound called Chlorobutylean Rubber ("ChuB"). These compositions have improved durability against environmental factors such as sunlight exposure, temperature variations, rainwater damage, snowfall, salt sprays, etc., while also having better flexibility than traditional cables made from plasticized polyvinyltoluate due to their high thermal stability at low temperatures. Additionally, this new design includes adding certain fillings including talc powder, iron flakes, calcium stearns, bismuth triazines, dithianonaphtheniums, quaternary ammonium salts, and other substances can further enhance its overall characteristics. Overall, these technical improvements result in enhanced mechanical properties over existing cables without compromising on safety standards.

Problems solved by technology

The technical problem addressed by this patented technology relates to providing strong yet flexible cables made from materials like neoprenes (neopolyisocyanate), chlorothioethers(chlorotrioxy) rubbers, epoxy resins, silicone polymers, polyimides, polysulfonamines, vinyl esters, etc., while also having superior thermal insulation, waterproofness, solvents resistances, and durabilities over existing technologies such as EVOH/NBR).
