Patent ID: 8474189

Claim:
A weather strip comprising: a stem portion configured to secure the weather strip to a frame structure, the stem portion comprising a thermoplastic polymer; and a hollow bulb portion secured to a first end of the stem portion, the hollow bulb portion comprising: a bulb wall having an inner-facing surface, and comprising a first thermoplastic elastomer that exhibits a Shore A hardness of 20 or less, and that is selected from the group consisting of a thermoplastic vulcanizate material, a styrene-based block copolymer, and combinations thereof; and an inner coating disposed on at least a portion of the inner-facing surface of the bulb wall, wherein the inner coating comprises a second thermoplastic elastomer that exhibits a lower self adhesion relative to a self adhesion exhibited by the first thermoplastic elastomer of the bulb wall, and wherein the second thermoplastic elastomer of the inner coating has a higher durometer than the first thermoplastic elastomeric material of the bulb wall and the second thermoplastic elastomer having a coefficient of friction of 0.50 or less; wherein a continuous segment of the weather strip is configured to be bent for substantial alignment with a corner of a frame structure having an angle ranging from 60 degrees to 100 degrees.
