Profile strip for a motor vehicle and profile strip production method

A profile strip for a motor vehicle, comprising:

• a securing profile section that can be secured on a first part of the motor vehicle, and
• a sealing profile section connected to the securing profile section, produced from a vulcanized rubber matrix and configured to allow relative movements with reduced friction between the profile strip and a second part of the motor vehicle, wherein a contact surface of the sealing profile section that can be brought into contact with the second part is provided with an anti-friction coating that comprises an anti-friction coating matrix and anti-friction particles embedded in the anti-friction coating matrix that are produced from ultra-high-molecular-weight polyethylene (UHMWPE),
• wherein the anti-friction coating matrix is a vulcanized ethylene-propylene diene monomer (EPDM) matrix,
• wherein the anti-friction coating is produced from an EPDM mixture that comprises the following components:
• 20 wt % to 40 wt % of the anti-friction coating matrix, which is EPDM, and 3 wt % to 50 wt % of the anti-friction particles, and
• wherein the anti-friction coating is formed directly on the vulcanized rubber matrix of the sealing profile section.

A profile strip for a motor vehicle, comprising:

• a securing profile section that can be secured on a first part of the motor vehicle;
• a sealing profile section that is connected to the securing profile section, the sealing profile section includes a sealing profile section matrix and a contact surface;
• and
• an anti-friction coating that is formed on the contact surface and is configured to allow relative movement with reduced friction between the profile strip and a second part of the motor vehicle, the anti-friction coating includes an anti-friction coating matrix and anti-friction coating particles,
• wherein each of the sealing profile section matrix and the anti-friction coating matrix includes an ethylene-propylene diene monomer (EPDM) material, the anti-friction coating particles are embedded in the anti-friction coating matrix and include ultra-high-molecular-weight polyethylene (UHMWPE), and the sealing profile section matrix and the anti-friction coating matrix are co-extruded so that the anti-friction coating is formed directly on the contact surface while the (EPDM) material of the anti-friction coating matrix is vulcanized.
