Functions
Heat aging resistance
Concept
Due to its uniform cross-linked structure, VNB-EPT has superior heat aging resistance compared to existing ENB and DCPD-diene type EPDM.
Applications
- Gaskets
- Conveyer belts
- Hoses
- Anti-vibration rubber
- Electric wires
Heat aging resistance (elongation change)
- VNB-EPT
- DCPD type
- Low-ENB type
- Medium-ENB Type
- High-ENB Type
Wear resistance
Concept
VNB-EPT has excellent wear resistance, and exhibits superior wear resistance even after aging.
In particular, in applications such as conveyor belts that demand wear resistance, replacement costs and GHG emissions can be expected to be reduced as product life is extended.
Applications
- Conveyor belt (covering layer)
Abrasion resistance (DIN abrasion comparison)
Improved compression set
Concept
In comparison with typical ENB-type EPDM, VNB-EPTs offer an excellent balance between elongation and compression set.
Applications
- Gaskets
Elongation and compression set
- VNB-EPT
- DCPD type
- Low-ENB type
- Medium-ENB Type
- High-ENB Type
Cross-linking efficiency
Concept
VNB-EPTs using VNB-type dienes with good reactivity have better cross-linking efficiency than ENB-type EPDM, enabling reduction in the amount of peroxide used in the formulation.
Applications
- Gaskets
- Conveyer belts
- Hoses
- Anti-vibration rubber
- Electric wires
Vulcanizing torque
(Change in vulcanizing agent in formulation)
- VNB-EPT
- DCPD type
- Low-ENB type
- Medium-ENB Type
- High-ENB Type
New cross-linking technology
Concept
High-speed vulcanization is achieved by combining VNB-EPT with new cross-linking technology.
Shortening the vulcanization time during processing can be expected to lead to reductions in GHG emissions.
Applications
- Gaskets
- Conveyer belts
- Hoses
- Anti-vibration rubber
- Electric wires
