Weather strip for use with frame structures having sharp corners

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.
