| URAPROTECT, a protector of communications and electricity cables, protects special pipes and sea floor cables for sea floor installation from shock and abrasion. We developed a polyurethane material for marine use and applied for patent of it. Using the material, Dong Won EN-TEC develops, produces and provides the products suitable for the features of each marine project including a protector (URAPPROTECT) for cables installed in the sea floor and marine oil fields. |
| |
| URAPROTECT protects cable from shock derived from anchor, due to its excellent elasticity, corrosion-resistance, hydrolysis-resistance and insulation attributes. Moreover, there will be no clothing damage to cable, because of the affinity of URAPROTECT with cable, and no abrasion will be found even in the sea floor environment where ground subsidence takes places and rock mass collides. The durability of URAPROTECT will last more than 50 years under the sea floor environment with outstanding abrasion-resistance, where cables and pipes cross. |
| |
| The basic product unit is 1.5m and the installation working time in the sea floor can be reduced. |

| * The urethane material used for seafloor cable protection should prevent hydrolysis, and elasticity, tension intensity and friction resistance have to be excellent, in view of the polyurethane characteristics on the seafloor. The cover for seafloor cable protection should be superior in scratch and friction resistance and have outstanding hardness and elasticity. The cover also must be at least equal or beyond the NEP products under Article 16 of the Industrial Technology Innovation Promotion Act and Article 18 of the Enforcement Ordinance of the same Act, and should have the above-mentioned polyurethane product dimensions minimum. |
