Because their natural color is usually cream, white, beige or translucent, TPEs are very easy to color. Repurposing and recycling You can also make TPEs out of biopolymers, which are natural polymers produced by the cells of living organisms. For example, other plastics made out of natural resources such as sugar cane can be repurposed into TPEs to create new products.
