NEW BULLETPROOF MATERIAL-POLYUREA-CHINABALLISTIC.COM

In daily life, if we are careful enough, we will find that many skyscrapers, truck covers, oil platforms, and bulletproof equipment have a common material – polyurea. The popularization and promotion of polyurea is said to have originated from the experiments of a group of Italians. They tried to free fall the polyurea-coated watermelon from a height of 45 meters, and the watermelon bounced back when it landed, and its appearance was intact. In order to further verify the protective ability of polyurea, some people also tried to spray polyurea on eggs and tested, and the eggs were also intact. With its excellent protective properties, polyurea has become more and more widely used in various fields from heavy industry to agriculture, especially in the field of protective products, its application is also more and more promising.

Polyurea is formulated from specific raw materials in a specific proportion. Its specific material formulations are kept secret commercially, but the basic ingredients can be identified as a combination of isocyanate and polyol resin. Polyols primarily act as plasticizers, and when the two components are combined, they polymerize to form a long-chain molecule. Long chains of molecules are intertwined with each other to form an indestructible material called polyurea. In addition, these long-chain molecules are stretchable and have high flexibility, which also endows the polyurea material with ultra-high tensile and tear resistance.

In addition, polyurea has many performance advantages, such as:

Quick-drying – Polyurea coatings sprayed on surfaces such as various instruments and equipment can be dried and set in seconds and are ready for use.

Very high wear and compression resistance.

Good chemical resistance.

Super airtight and waterproof.

Does not contain VOCs, CFCs, solvents, etc., and does not cause any pollution to the environment.

It is precisely because of these characteristics of polyurea that it has a lot of attention to its use method and application. At present, polyurea is usually coated on the surface of objects by thermal spraying, which is time-critical because once the two components of the coating are combined, the reaction starts immediately and cannot be reversed. In the process of use, the two coatings need to be pressed into a special spray gun through a heated hose, the two are quickly mixed at the moment of spraying, and then quickly dried and formed in a few seconds.

Polyethylene
THE IMPROVEMENT AND APPLICATION OF POLYETHYLENE -CHINABALLISTIC.COM

In recent years, product research and development technology has been continuously improved, and various products are constantly innovating in terms of performance, materials, packaging and production technology. For bulletproof products, the limited protective performance and high weight have always been difficult obstacles to improve the performance of bulletproof products. Therefore, scientists and researchers in the field of bulletproof protection have always been involved in finding and developing new materials. At the same time, attempts are made to improve and enhance the performance of the original materials, and the new polyethylene (PE) is one of the new high-performance materials improved through new technologies.

The high-strength and functional polyethylene tape is made of special high-molecular-weight polyethylene, which is currently the strongest polyethylene material in the world. It is an upgraded version of ultra-high molecular weight polyethylene, so in addition to all the characteristics of ordinary ultra-high molecular weight polyethylene materials, it also has excellent characteristics that ultra-high molecular weight polyethylene does not have, such as high strength under the same weight And functional polyethylene tape is 11 times stronger than steel, and at the same time, compared with ordinary UHMWP, it has higher corrosion resistance, UV resistance and creep resistance as well as good thermoplasticity.

The excellent performance of this super polyethylene comes from its special processing technology and manufacturing process. Super polyethylene is to melt and press ultra-high molecular weight polyethylene particles to synthesize polyethylene film, and then stretch it to a thickness of 50-60um. At this time, the polyethylene molecular chain will be fully stretched and regular under strong pulling force. Arranged together, giving it far superior characteristics than ordinary ultra-high molecular weight polyethylene materials. These ultra-high molecular weight polyethylene films are then laminated together to obtain what we call super PE materials.

The bulletproof product made of super PE has a super energy absorption effect, it can disperse and absorb the kinetic energy of the bullet, so as to intercept the bullet and have a good bulletproof effect. Therefore, this super PE has been applied to bulletproof helmets, bulletproof inserts, and bulletproof vests and other bulletproof products.

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

Textiles and composites – some textiles are made with this super PE, and composites synthesized with this type of fabric have strong compression resistance. For example, adding super PE fibers to some carbon-containing composite materials and glass materials can enhance the strength and compressive ability of the composites.

Ropes, nets and cables—-Super PE has super high tensile strength, combined with its light weight, it is used as the best material for making ropes, cables, etc. In addition, its good corrosion resistance makes it more widely used.

In addition, super PE can also be used in the manufacture of air containers, sails, etc. As long as it is a product with high requirements for strength and light weight, super PE can participate.
