MTPU

Dense, abrasion-resistant and safety-ready under heavy load.

Draft — final copy to come

Placeholder introduction to MTPU (Microcellular TPU). This paragraph will explain what the material is, where it comes from and why it matters in performance footwear.

What is MTPU?

Placeholder text. A plain-language explanation of Microcellular TPU: its chemistry, how it is produced and how it differs from neighbouring compounds.

Placeholder text. A second paragraph with more depth for readers who want the technical detail.

How it performs in a sole

Placeholder text. How MTPU behaves underfoot — rebound, flex, weight, durability — and how that changes over the life of a shoe.

Where we use it

Placeholder text. Which footwear categories MTPU suits, which standards it helps meet, and how ALCMY processes it.

Processing and sustainability

Placeholder text. Molding methods, recyclability and sourcing notes.
