Let's talk about D3O material first
This material is already very popular. In recent years, a new upstart has appeared in foreign material market: D3O material, which has attracted people's attention. This is a special polymer material. D3O LAB calls it Smart Material. It is very pleasant to touch. It is soft, but it becomes very hard under external force, which can provide excellent protective performance, and shows great application prospects in field of sports protection and anti-collision protection.
This material is soft to touch, similar to plasticine, and seems to be nothing special.
But! Soft materials can show an extremely "hard" side and use it to coat eggs, and eggs cannot be broken with a hammer.
This is a new D3O material that has made a strong showing in sports protection market in recent years. At present, D3O is used in many foreign products, from mobile phone cases to sports protective equipment and ballet flats. While name sounds like you don't know what it is, its function is still very mundane: crash protection, energy absorption, and cushioning.
Unlike high-strength materials such as steel, D3O is soft under normal conditions but can withstand sudden force impacts.
D3O is a product launched by D3O LAB in UK. Intense bright orange color. It is used in a range of crash protection measures, from motorsport, winter sportswear and even on battlefield. D3O materials are mainly used in sportswear protective equipment, such as ski suits, motorcycle suits, cycling suits, ice and snow sportswear, etc., as well as police and military protective equipment.
D3O in its original state is very easily deformed, but if an external force is quickly applied to it, it will suddenly solidify and immediately absorb external energy.
Let's talk about P4U materials,
From public information (company portal website: http://www.i-p4u.com) we can learn that P4U is named after "Protect for you", protecting your value . , focusing on various kinds of impact protection: collision prevention, falling, cushioning, energy absorption, cushioning. The color is red.
On official website, P4U material is referred to as a kind of intellectual material, which has a national invention patent and is protected by national intellectual property rights. This is a new type of material independently developed by Chinese scientists. Dr. Li Feng, Senior Research Fellow, PhD student, MINTEK National Research Institute.
P4U Intelligent Anti-collision Gel belongs to category of intelligent polymer materials. It is a smart gel that senses, reacts to its environment and has ability to make discoveries.
Its characteristics are exactly same as those of D3O. And execution of this new company material is more varied than D3O's (seems like there's more than one material.
P4U intelligent anti-collision gel material stays relaxed under normal conditions, soft and supple. After a strong impact or extrusion, molecules immediately block each other, quickly contract and harden to digest external forces and form a protective layer. layer, when external force is gone, material will return to its original relaxed soft elastic state.
It can react differently to different impact situations within nanoseconds. In fact, it is a non-Newtonian liquid substance, and its viscosity is completely different from viscosityliquids in Newtonian physical models such as water and gasoline.
P4U performance can be like wet sand. When wet sand is moved slowly by hand, grains of sand will flow freely and displace each other; if it is suddenly made to move, the grains of sand will interlock and cling together to form a solid mass.
For P4U gel, action usually occurs within a fraction of a second or less, and faster action or stronger action, stronger effect (in extreme range).
Before impact: submicron active ingredients dispersed in P4U media;
During impact: under high shear, active ingredient particles rapidly agglomerate under P4U medium;
After exposure: The particles of active ingredient are evenly distributed again.
It can be used in following five areas:
1. Personal Protection - ski suits, motorcycle suits, cycling suits, taekwondo suits, kendo suits, stunt protective clothing, helmets, hip and knee pads, elbow pads, gloves, insoles, soles, etc., and police officers . use , military protective equipment;
2. Electronic equipment - large screen smart mobile phones, laptops/tablets, precision shock absorption;
3. Protection of cars / electric vehicles - protective stickers, bumpers, energy-absorbing boxes, protection of power batteries;
4. Buildings, bridges - locks, shutters;
5. Modified materials - PU, silica gel, TPU, TPE modified materials.
