<p>The object of this invention is to provide an improved soft barrier fin weatherstrip 10 and method of manufacturing same. The weatherstrip 10, which is used for sealing openings between fixed and sliding members, comprises a soft barrier fin 16 preferably formed from polypropylene material. The fin 16 is coated or impregnated with paraffin which fills the openings or interstices in the fin. The coated fin 16 has good resistance to air and moisture infiltration. The fin 16 further reduces the noise generated by the weatherstrip 10 sliding on a mating surface, and the break-away force required to reverse the direction of the fin. The paraffin in the fin 16 acts as a lubricant between the weatherstrip 10 and mating surface.</p> |
