In recent years, product research and development technology has been continuously improved, and various products are also constantly innovating in terms of performance, materials, packaging, and production technology. For bulletproof products, limited protective performance and high weight have always been obstacles that hinder us from improving the performance of bulletproof products. Therefore, scientists and researchers in the field of bulletproof protection have been searching for and developing new materials, while also trying to improve and enhance the performance of existing materials. The new PE is one of the new high-performance materials improved through new technologies.

High strength and functional polyethylene tape is made of special high molecular weight polyethylene and is currently the strongest polyethylene material in the world. It is an upgraded version of ultra-high molecular weight polyethylene, so in addition to possessing all the characteristics of ordinary ultra-high molecular weight polyethylene materials themselves, it also has excellent characteristics that ultra-high molecular weight polyethylene does not have. For example, under the same weight, the strength of high-strength and functional polyethylene tape is 11 times that of steel. At the same time, compared with ordinary UHMWP, it has higher corrosion resistance, UV resistance, creep resistance, and good thermoplastic properties.

The excellent performance of this super polyethylene comes from its special processing technology and manufacturing process. Super polyethylene is a polyethylene film formed by melting and pressing ultra-high molecular weight polyethylene particles, and then stretching them to a thickness of 50-60um. At this time, the polyethylene molecular chains will fully extend and arrange together in a regular manner under strong tensile force, endowing them with excellent properties far superior to ordinary ultra-high molecular weight polyethylene materials. By laminating these ultra-high molecular weight polyethylene films together, we obtain what we call super PE materials.

The bulletproof product made of super PE has a strong energy absorption effect, which can disperse and absorb the kinetic energy of bullets, thus effectively intercepting bullets and achieving good bulletproof effect. Therefore, this super PE has been applied to bulletproof helmets, bulletproof Plate, and bulletproof vests.

In addition, this new type of super PE has also been applied to multiple fields, such as:

Textiles and Composite Materials - Using this super PE to make some textiles, composite materials synthesized from these fabrics have strong compressive strength. For example, adding super PE fibers to some carbon containing composite materials and glass materials can effectively enhance the strength and compressive strength of the composite.

Ropes, nets, and cables - Super PE has ultra-high tensile resistance, combined with its lightweight characteristics, making it the best material for manufacturing ropes, cables, and other materials. In addition, its good corrosion resistance makes it more widely used.

In addition, super PE can also be applied to the manufacturing of air freight containers, sails, and so on, as long as products with high requirements for strength and lightweight can have the participation of super PE.
