What is the difference between visors?
Polycarbonate - protection against impacts, liquid splashes and splashes of molten metal. Meets 120m/s impact resistance (class B). The best material to choose for inorganic chemicals, including acids, and can withstand radiant heat at high temperatures (the material will begin to change shape when it reaches its maximum temperature). Acetate - protection against impacts and liquid splashes. Meets 45m/s impact resistance (class F). Good scratch resistance. The best material to choose for organic chemicals, including organic solvents.
Thermoguard™ - protection against impacts, liquid splashes and splashes of molten metal. Meets 45m/s impact resistance (class F) and can withstand radiant heat at high temperatures (the material will begin to delaminate when it reaches its maximum temperature - this is also a safe indication that the visor's surface temperature is too hot).
Gold - protection against impacts, liquid splashes and splashes of molten metal. Meets 120m/s impact resistance (class B) and can withstand radiant heat at high temperatures by reflecting heat and thereby reducing the material's surface temperature (the material will, however, ultimately change shape).
Metal mesh - protection against heat. Metal mesh visors absorb heat. They do not protect against splashes of molten metal and additional eye protection should be used.
Forestry mesh - protects against large, solid particles and wear. This type of mesh visor is suitable for pruning, brush cutting, sawing and trimming - environments where there is a significant risk of large pieces of solid material and constant abrasion. Additional eye protection should be used under the visor.
