Chemical Resistant PU Spider Element
Polyurethane elastomer is a synthetic polymer material that combines the high strength of plastics with the high elasticity of rubber. These couplings are manufactured using high-quality TPU material or CSM/SBR molds, specifically designed for various metal shaft coupling applications.
Key Material Properties
- Wide hardness range (Shore A10-D80) with excellent elongation and resilience
- High tensile strength, tear strength, and load carrying capacity
- Outstanding wear resistance - 3-5 times better than standard rubber
- Excellent oil resistance with low affinity for non-polar mineral oils
- Superior oxygen and ozone resistance
- Excellent vibration absorption and damping capabilities
- Good low temperature performance
- High radiation resistance
- Excellent machining properties
