Temperature has no effect on the hardness of silicone rubber tube?
Silicone tube production, the temperature has no effect on its hardness? Temperature can affect the reaction rate of the catalyst, which is the rate of curing, but the hardness of the silicone tube has no effect? Under discussion.
Summer temperatures rise, if not in the measurement of silicon tube hardness testing standard under constant temperature and humidity environment, there will be the phenomenon of low. Winter temperatures decreased, there will be a high phenomenon.
Analysis of Qi Yu silicone hose manufacturers: as for how to keep the constant temperature and humidity, and now is ventilation, over off time estimation to open air conditioning. The only change in the test results is the temperature, but this summer, the winter temperature difference is less than 20 degrees. Regardless of the new formulation and the old formula, light formula are easy due to sulfur, it would seriously affect the test results, and the test temperature also has a relationship, recommendations or Gaby table area slightly larger silica as a reinforcing agent, and other light colored packing and use, the effect will be surprisingly good, you will get unexpected results. In addition, the increase in the number of points, the increase in hardness is not as much as possible, it may be that the extent of the increase in the degree of molecular chain, resulting in the final cross link density.
