SEPTON™ is a series of high performance thermoplastic rubbers developed by KURARAY CO., LTD. using its unique isoprene technology.
In terms of structure, SEPTON™ is a series of hydrogenated styrenic block copolymers, and it exhibits rubber-like properties over a wide range of temperatures. Its remarkable characteristics are as follows: |
| |
- Excellent Mechanical Properties
- Superior Heat Resistance
- Good Weatherability
- Excellent Chemical Resistance
- Excellent Low Temperature Properties
- Low Toxity
- Excellent Electrical Insulation Properties

| Prior to processing, the polystyrene end blocks are associated in rigid domains. In the presence of heat and shear such as during processing, the polystyrene domains soften and permits flow. After cooling, the polystyrene domains reform and harden, locking the rubber network in place. This physical phenomenon provides SEPTON™ with its high tensile strength and its elasticity. Since SEPTON™ is a thermoplastic, it is recyclable. |
