Abstract
A description is given of a molding compound made of elastomeric polyolefin rubbers, polyethylene and/or ethylene copolymers and additives, said compound comprising per 100 parts of polyolefin rubber, 25 to 100 parts by weight of polyethylene and/or ethylene copolymers having a MFI (190/2,16) of less than 0.1 [g/10 min], and between 16 and 28 parts by weight of a mineral oil. Also described is an elastic sealing strip, more particularly a roof sealing strip, made from the said molding compound by calendering or extruding.
