Polymer — Extrusion

: Companies like A-SAFE have used these techniques to rebuild after disasters, moving from making simple film wrap to inventing solid polymer safety barriers that protect people in warehouses worldwide.

: Now a thick fluid, Poly is forced through a specifically shaped opening called a die . Think of it like squeezing toothpaste through a star-shaped nozzle—Poly takes on the shape of that opening, whether it’s a hollow pipe, a flat sheet, or a thin fiber.

: As Poly exits the die, she finally gets to cool down. She passes through a water bath or an air-cooling system that hardens her back into a solid, but now in her brand-new, permanent shape. Why This Matters
