P4U Smart Crash Protection Gel belongs to the category of smart polymer materials. It is a kind of smart gel that can sense and respond to the environment and has the ability to discover. Smart gel is through the molecular design and organic synthesis method to make the organic material itself with the biological endowed with advanced functions: such as self-repair and self-proliferation ability, recognition and identification ability, stimulus response and environmental strain ability, etc. P4U smart collision protection gel material in the normal state to maintain the relaxation of the state, soft and elasticity, once subjected to severe impact or extrusion, the molecules are immediately locked with each other to rapidly tighten and harden so as to digest. Once impacted or squeezed, the molecules immediately lock with each other and rapidly tighten and harden to digest the external force, forming a protective layer. When the external force disappears, the material will return to its initial state of relaxation and soft elasticity. It can react differently to different impacts within nanoseconds. In fact, it is a non-Newtonian fluid substance, its viscosity is completely different from the Newtonian physical model of liquids, such as water and gasoline. the effect of P4U can be associated with wet sand. When the wet sand is moved slowly by hand, the grains flow freely and are displaced from each other; if it is suddenly forced to move, the grains interlock and become a hard mass. For P4U gel, the impact often occurs in a fraction of a second or less, the faster the movement or the heavier the impact, the stronger the effect (in the extreme range). Before impact: submicron active ingredients dispersed in the P4U medium; impact: high shear rate action, the active ingredient particles in the P4U medium under the action of rapid agglomeration; impact: the active ingredient particles and then back to a uniformly dispersed state.
Can be used in the following five areas:
1. personal protection - ski suits, motorcycle suits, cycling suits, taekwondo suits, kendo suits, stunt protection clothing, helmets, hip protectors, knee protectors, elbow protectors, gloves, insoles, soles, etc., as well as the police, military protective equipment;
2. electronic equipment - intelligent large-screen cell phones, laptops / tablets, precision shock absorption
3. automotive/power car protection - protective patches, bumpers, energy-absorbing boxes, power battery protection;
4. construction, bridges - speed lockers, dampers;
5. modified materials - PU, silicone, TPU, TPE modified materials.
