Polyurethane is the timing belt material of choice for BRECOflex. Polyurethane is a broad spectrum of many thermoplastic elastomers that are best suited for specific applications.
There are currently 16 types of polyurethane timing belt materials available. The standard is TPU-ST1 which is used for all belt type and BFX belts longer than 720mm. The standard color is white and the hardness is 92 Shore A. This material is suitable for most applications but if you require something else, see the charts below:
What are the benefits of using polyurethane timing belts over other materials?
- Extremely wear resistant
- Extensive temperature range
- Resistant to petroleum, oils and fats
- Ozone and sunlight resistant
- No lubrication required
- High tooth shear strength
- High tension resistance
- Allows belt processing with no loss in material properties
- Non-marking
