For compressed nitrile butadiene rubber products, pressure is an important indicator, but it is not easy to do well, the following Lianxing rubber on their own experience for nitrile butadiene rubber products pressure problems to make solutions.
In terms of raw rubber, the following points are beneficial to improve the pressure performance:
1, choose a low saturation;
2, the content of acrylonitrile is low;
3. The viscosity of promenil is higher.
Other aspects
4, ensure sufficient vulcanization, can consider sulfur and peroxide combined system;
5, the packing particle is larger;
6, antioxidant selection of heat-resistant type.
