Polyethylene Fiber/Polyethylene Yarn
DOYENTRONTEX® fiber is an UHMWPE (Ultra High Molecular weight Polyethylene) fiber developed by BJTYZ about 20 years ago.DOYENTRONTEX® fiber has a unique combination of properties. The density is slightly less than 1 g/cm3, so the fiber floats on water. But the tenacity is the highest in the world and can be up to 15 times that of a good quality steel. The modulus is very high and is second only to that of special carbon fibers grades. Elongation at break is as low as for other high performance fibers, but due to the high tenacity the energy to break is high. Nowadays DOYENTRONTEX® fiber has been used in lots of application areas.
High strength and high modulus,the tenacity can be up to 15 times that of a good quality steel
Low density:0.97g/cm3, lighter than water
High impact resistance
Anti-aging and anti-UV capability
Corrosion and sea water resistance
Abrasion and fatigue resistance
Low dielectric constant,high electrical resistance and a dielectric loss factor
Temperature resistance:the strength and modulus increase at low temperature
Personal protection(Body armor, Bomb suppression blanket, Ballistic helmet, Ballistic plate)
Bulletproof armour (Armored vehicle, Police vehicle, Anti-explosion yacht)
Oceaneering(Drilling platform, Anchor cable, Towrope, Mooring rope, Terminal hoisting rope)
Industrial application(Cut-resistant glove, Hoisting rope, Wind power cable)
Aerospace engineering(Re-entry module of shenzhou spacecraft recovery system, Aviation cages, High precision space craft)
Marine fishery(Commercial fishing nets, Marine aquaculture net)
Outdoor sports(Climbing rope, Parachute rope, Sailing rope, Kite line, Fishing line)

Company Introduction
Beijing Tongyizhong New Material Technology Corporation (TYZ), a certified company by ISO 9001:2015 and affiliated to the State Development and Investment Corporation (SDIC) and held by China SDIC International Trade Co., Ltd, is one of the largest and earliest manufacturers for UHMWPE/HMPE fiber since 1994 and its composite ballistic materials including but not limited to PE UD, aramid UD and other ballistic products.
As a National High-tech Enterprise specialized in R&D, production and sales of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber and its composites, BJTYZ has become a word-famous high performance fiber supplier that employs over 500 staffs and covers plant area of 50000 square meters through 20 years' fast development.
TYZ, one of the first domestic enterprises doing industrial technology research on UHMWPE fiber, launched the research since 1994, and has become one of the three companies took the lead in realizing the industrialization of Gel Spinning of UHMWPE fiber. As a leading enterprise in UHMWPE fiber, with 20 years' development, BJTYZ has its own complete intellectual property rights for key technologies. They have filed 45 patent applications, among which 30 inventive patents have been authorized, including 1 European patent and 1 Korean patent. These inventive patents cover all the technological areas of UHMWPE fiber and its composites. BJTYZ also took charge of the draft of the industrial standard for UHMWPE fiber, which had been approved by MIIT and officially promulgated and implemented on April 1st, 2011.
BJTYZ has already built up the research & development center which has an innovation team of 90 technicians, including nearly 30 postgraduates. Their developmental achievement has won the Second Prize for National Science and Technology Advance in 2009, also their inventive patent has achieved the 11th China Patent Award of Excellence in 2009. BJTYZ has formed strict production management and inspection & test system, and has got both ISO 9001: 2015 Quality Management System Certificate and GJB9001C-2017 National Military Quality Management System Certificate. With good quality, stable performance and reasonable price, DOYENTRONTEX® Fibers and composites are widely recognized by both domestic and overseas customers. Based on the powerful research and transformation capability of scientific and technological achievements, BJTYZ holds the ability to provide customers with various solutions. DOYENTRONTEX® Fiber has been successfully used in the final maritime salvage and recovery parachutes of the "SHENZHOU Spaceship 5, 6, 7, 8, 9", the military amphibious tank beach gear system and the emergency landing system of war craft runaway, which have made great contributions towards strengthening the construction of national defense and public safety equipment in the world.
