Bulletproof Material

Powder form allows customisable potency to fit individual skincare needs. Depending on your skin's needs, you can create your own serum, cream or toner by adding a specific amount of hyaluronic acid powder to your favorite skincare products.
Carbon fibers are processed to form manufacturing intermediates like dry carbon fiber fabrics, prepregs, etc., which are further used to make carbon fiber composite parts used in real-life applications. Carbon fibers from tows are used to make fabrics (woven or non-woven). Depending on how these fibers will be oriented — fabrics can be of different types, such as uni or bi-directional, multiaxial, random, etc.

In UDs, a larger percentage of the fiber weight can be unidirectional carbon fibers, usually running in the warp (vertically up and down the roll of fabric) direction. The rest can often be a resin binder or a secondary material like a weft stitch running in other directions, holding the fibers together.

For example, in prepreg unidirectional tapes, fibers are impregnated with resin (like epoxy or vinyl-ester resins) that locks the parallelly running fibers in one place. While UD carbon fiber fabrics can be used as reinforcements for larger structures, UD tapes can have a localized application to reinforce narrower components like skis.

Unidirectional composites also use UD carbon fiber fabrics as reinforcement. These UD reinforcements can be overlapped at different angles to obtain unique properties. UD composites (with longitudinal, continuous fibers) have the greatest strength of all composites. Moreover, advanced composites also owe their strength to unidirectional low-density plies – layers of UD fibers in a matrix. The final characteristics of UD carbon fiber fabrics or composites — like the strength, elasticity, drapability, etc. are greatly influenced by the orientation and distribution of the fibers.

Lightweight
If you need rifle-rated protection from a plate that's less than 4 pounds, PE is for you. The lightweight design allows you to engage in physically strenuous activities. Heavier plates tend to cause quicker fatigue. That's the primary benefit you'll get from PE armor plates.
Resistance to corrosion
Resistance to corrosion, polyethylene pipes do not rust, they do not allow the creation of cavities, are not sensitive to stray currents and do not promote bacteriological growth (iron-oxidising bacteria). They can pass immune through areas characterised by a strong presence of chemically active environments.
Efficient ballistic performance
PE material can effectively absorb and disperse the energy of bullets, providing excellent protective effects.
Temperature sensitivity
PE material may deform at high temperatures, so the temperature range of the operating environment needs to be considered when choosing pure PE ballistic plates.
Thickness
To provide higher levels of protection, it may be necessary to increase the thickness of pure PE ballistic plates, which could affect flexibility and comfort.

A PE plate — also called an armor plate, ballistic plate or trauma plate — is inserted into a bulletproof vest to provide additional protection for the wearer. Basically, the NIJ sets the testing standards and protocols for PE plates. To evaluate overall safety and effectiveness, it determines the threat and caliber level the armor in question can withstand. More specifically, it aims to ensure a bullet won't puncture the plate and expose the wearer to blunt force trauma. Here's the thing about the NIJ's body armor levels — each one provides a different level of protection. The NIJ currently has five threat levels, and each one is classified by the caliber of bullet it can stop. The five threat levels are:

Level IIA
This is the current lowest NIJ protection level. Sorry, Level IIA, but at least you made the cut!
Level IIA is the lightest and most flexible among the five, but it's largely outdated and not a first choice for many. Typically a form of soft armor and easily concealable beneath clothing, Level IIA protects against 9mm and .40 S&W ammo from short-barrel handguns. It doesn't offer protection from rifle ammunition.

Level II
While Level II body armor offers slightly more protection than IIA, it's also not really considered one of the big guys. A relatively soft and thin ballistic body armor, it's designed to protect from common handgun rounds — usually up to .357 Magnum rounds from short barrels and 9mm.
Like IIA, Level II plates are flexible, light and discreet under clothing, but they defeat a higher ammunition range than IIA and offer more blunt force protection. Due to their lightweight nature and overall ease of use, Level II options can be popular choices for some police forces and even security-conscious citizens.

Level IIIA
Now, here's where we start to segue into the more heavy-duty stuff. While Level IIIA does not provide rifle protection, it's been tested by the NIJ to stop .44 Magnum and 9mm ammunition from longer barrel handguns — unlike levels IIA and II, which really only protect from short barrel rounds.

Level III
Level III body plates are the first to protect against rifle rounds. This type of body armor usually contains hard and heavy materials, so it's not quite as concealable. But with this heavy material generally comes greater protection. Level III plates are NIJ-tested to withstand a lead core rifle ammunition of 7.62mm.
Our level III plates protect against everything our level IIIA plates do, and are also tested to withstand common rifle calibers.

Level IV
Finally, NIJ Level IV provides the highest protection level, hence the higher number — makes sense now, right? It's been tested to resist armor-piercing rifle ammunition from a .30cal steel core.
