TPU 90A

Shore 90A shock-absorbing, vibration-damping elastomer.

A functional elastomer at 90 Shore A that flexes repeatedly, with 110% elongation at break. Used for seals, bumpers, vibration-damping mounts and flexible hinges. At 39 kN/m tear strength it stands up to abrasion, rebounding where rigid parts would crack.

APPLICATIONS04 / 04
01

Gaskets & Sealing Elements

Gaskets, bellows and sealing profiles. Its elastomeric structure lets it return to shape after repeated compression.

02

Vibration Dampers & Mounts

Engine and electronics mounts, impact pads. They absorb energy and cut the vibration passed into the structure.

03

Flexible Hinges & Bellows

Joints that open and close continuously, and telescopic bellows. 110% elongation at break gives repeated motion room to work.

04

Grip Faces & Gripper Pads

Robotic gripper pads and handle coverings. At 39 kN/m tear strength they last on contact faces that see wear.

MATERIAL SELECTION

Choose TPU 90A When

  • The part will compress, flex and then return to shape.
  • Vibration or impact energy needs to be damped.
  • You are targeting rubber-like behaviour at 90 Shore A hardness.
