TPU – semi-elastic thermoplastic polyurethane

TPU is a rubbery flexible plastic, that can still endure admirable mechanical stress. TPU is suitable for any project that requires a flexible, bendable part that doesn’t easily break. It is commonly used in various medical fields, tool manufacturing and even phone cases. TPU is biodegradeable and isn’t toxic.

There are two types of TPU, varying in flexibility: TPE 32 a TPE 88.

Examples of use:

Merchandise – phone cases
RC Models
