Ballistic materials

The materials used to make our ballistic liners are constantly being refined and the manufacturing technology is continually being improved upon to that the materials we use now are thinner, lighter, yet also many times stronger.

Kevlar od DuPont

Kevlar material - picture

Kevlar is an organic fibre from a group of aromatic polyamides (ARAMID). Kevlar has a unique combination of high strength, high toughness module and thermal stability. It is also chemically stable to the whole range of chemical compounds, even those such as acids and alkalis. In practice there are a whole range of different types of Kevlar, which differ primarily in how they are used. Kevlar fibre does not melt, but breaks down at a relatively high temperature, within the range of 427 to 482 degrees Celsius. It also reliably retains its ballistic properties up to this temperature. The Kevlar fabrics used to make soft armour are produced from fibres of varying dtex; this results in fabrics with different degrees of softness. It is down to the customer which type to choose. For ballistic applications this product has been used for more than 30 years. Nowadays, however, the para-amide we offer has advanced several generations.

Twaron od Akzo Nobel

Twaron is a para-amide fibre characterised by its high strength, high elasticity module, low density and high energy absorption. It is also highly chemically resistant and can withstand high temperatures. It is electrically non-conductive. Its quality is also characterised by its dtex number. When making its soft vests Petris uses fabrics that are treated to make them water repellent. For ballistic applications this product has been used since 1986.

Dyneema UD od DSM

Dyneema a super-strong polyethylene fibre developed and patented by DSM in 1979, is 10 times stronger than steel. It features a high specific module, low elongation at break, high resistance to abrasion, UV radiation and chemicals, and last but not least, high energy absorption. This is one of the most important factors in the trauma effect, which is relatively low when these materials are used. Soft vests are made primarily from SB-2 materials with a density of 155g/m2 and SB-31 with a density of 132g/m2. HB 2 products are used to produce hand panels.

Combination of aramid and Dyneema

GARED s. r.o. has developed a combination of the unique properties of aramid and the Dyneema ballistic system to make soft bulletproof vests using the excellent heat resistance of aramid with the low density and high strength of Dyneema. This system is both comfortable and light and provides excellent ballistic protection, including good trauma effect.
