PAHs

What does PAHs mean ?

(polycyclic aromatic hydrocarbons)

The main objective of the PAHs test according Directive 76/769/EC is the restriction of potential cancer.  

PAHs are added in to rubber and plastic (such as soft PVC and ABS) as plasticizers to soften the materials.

A high amount of PAHs is also found if mineral oils used in plastic manufacturing processes.

If the used equipment is not maintained and clean enough, the produced rubber and plastic parts may contain PAHs.

Summary of PAHs 200 mg/kg
B¦ÁP 20 mg/kg
Long time contact (usually defined as touching for more than 30 seconds) allows a maximum of:

Summary of PAHs 10 mg/kg
B¦ÁP 1 mg/kg
