Plastventilasjonskanal som har i det minste to lag og er lagd i det minste delvis antistatisk

摘要

A ventilation duct is for example made of a polyolefin, such as polypropylene, polyethylene or cross-linked polyethylene. The ventilation duct (1) has at least two layers (2, 3, 4). The ventilation duct (1) has a permanently antistatic inner layer (2) and a temporarily antistatic outer layer (3). For example, the plastic material of the outer layer (3) is mixed with a short-term antistatic additive.
