General about Protection Factor

Protection factor is a measure of how much the content of pollutants decreases with protection. A protection factor of 100 reduces the level of pollutants in the ambient air 100 times, for example from 50 to 0.5 ppm. At the same time, the protection factor indicates how many times longer you can be, e.g. in hazardous gas, compared to without protection. For example, protection factor 500 gives that one hour without protection corresponds to 500 hours with protection.

Protection factor / Penetration

The studies that have been done on the garments have analysed the penetration of hazardous PAHs. Penetration is the opposite of the protection factor, so if the penetration is, for example, 1/1000, the protection factor is 1000.

CPP's activated carbon is both highly activated and has a significant dynamic adsorption capacity. This means that it has a high absolute capacity, and at the same time a high dynamic capacity through its well-balanced system of both larger pores which function as transport pathways and smaller pores which binds the molecules. CPP’s activated carbon has a high adsorption capacity even for low gas concentrations. The absolute adsorption capacity of gaseous PAHs has been found to be so high that the activated carbon retains a sufficient adsorption capacity even up to 24 smoke dives (10 hours) with intermediate washes.

Unlike other activated carbon, CPP's carbon is also very mechanically stable and does not crumble under pressure or wear.

Protection factor for CPP's undergarments

The protection factor indicates how many times longer you can stay in fire gas compared to without protection. See our studies for more detailed info

New (unused) garments:
Standard1 has a protection factor of 15
CPP2 has protection factor 3300
=> CPP has about 220 times better protection against PAH

Garments used in 12 smoke dives of 25 minutes each3
Standard1 has a protection factor of 11
CPP2 has a protection factor of 660
=> CPP has about 66 times better protection against PAH

Garments used in 24 smoke dives of 25 minutes each4
Standard1 has a protection factor of 7
CPP2 has a protection factor of 132
=> CPP has about 19 times better protection against PAH

The difference between the skin's average exposure of PAHs during those 24 smoke dives (600 min/10 hours) without vs with CPP is:

70 times higher - that is 35 years with CPP gives less exposure of PAH to the skin than 6 months with standard5
