Composite high performance fiber-rubber diaphragm, using a special technique and one-step forming to strengthen the uniform structure of ring, with low temperature secondary thermoforming, completely avoid high temperature hot melt process disrupted quality problems, enhance stability, greatly reduce maintenance costs. The temperature range of composite high performance rubber is -40 degrees Celsius to 220 degrees, the temperature range of neoprene rubber is -5 degrees Celsius to 120 degrees.
