Each item is produced in the most suitable material, in order to guarantee its correct technical functionality.

NYLON 6 – NYLON 6.6

PA6 – PA6.6

  • High mechanical strength
  • Excellent rigidity
  • Outstanding toughness even at sub-zero temperatures
  • Good fire resistance
  • Good resistance to oils, fats, and solvents
  • Good dyeability

Nylon absorbs 2.5% of its weight to reach the exact equilibrium point. The difference between 'humidified' and 'dry' Nylon is crucial for the strength tests, which are conducted under balanced humidity conditions.

POLYESTER

PBT

  • High rigidity and hardness of materials
  • Low creep tendency
  • High short-term distortion temperature up to 200°
  • Good abrasion resistance
  • Good insulating properties
  • Minimal water absorption
  • Good chemical resistance
  • Good low-temperature impact resistance

POLYPROPYLENE

PP

  • Excellent chemical resistance, including to acids
  • Balanced ratio of toughness, rigidity, and hardness
  • Low water absorption

ACETAL

POM

  • High rigidity
  • High mechanical strength
  • Good elastic properties
  • Excellent impact resistance
  • Good resistance to oils, fats, and solvents
  • Low water absorption

FLAME-RETARDANT NYLON

PA VO

Flame-retardant nylon Category V0 ensures high resistance to high temperatures and a flammability rating in accordance with UL94 standards. Specifically, once the sample is removed from the flame, it must no longer burn or drip, as stipulated by the relevant standard.

Flame retardant materials

2M Italia also produces its items using flame-retardant materials. The primary material we use is called Polyamide V0 and is tested according to the UL94 standard, ensuring high resistance to high temperatures and a flammability rating in compliance with the aforementioned standard. In this case as well, we can provide the relevant technical datasheets and test reports.

Flame retardant polyamide for technical garments

Essentially, the material ensures that, compared to a standard material, if the sample comes into contact with heat sources, once removed from the flame, it will no longer burn or drip as stipulated by the relevant standard.

These materials are designed to reduce the flammability of plastics (in our case, Nylon) by influencing the combustion process through various mechanisms, which are:

  • Gas release
  • Intumescence
  • Melting (absorbs heat that fuels the flame)
  • Action on the chemical reaction (slows down the rate)
