Anyone know what this insulation is?

Rubbery like foam but also soft like fabric and it's usually white. I need to replace this as mine is broken. I could possibly use foam. Just wondered if they sell this by itself? Not even sure how to search for it and nothing is coming up for a windshield seal for just this part.
