Silicone products white is mainly in the high-temperature environment leading to the analysis of its silica, the main reason and silicone products out of the frost is a principle.
The main reasons are: 1, improper adjustment of blended silicone rubber raw materials; 2, silicone products vulcanization temperature is too high, resulting in polymer degradation spray frost; 3, silicone products vulcanization temperature is too low, the local place is not vulcanized complete, thus causing whitening spray frost; 4, blended silicone rubber refining temperature is too high; 5, seasonal changes lead to.
If silicone products appear white phenomenon, you can take the following solutions: 1, the second vulcanization of silicone products, the second vulcanization of its silicone products more stable quality, more uniform material density; 2, the addition of special auxiliary materials in the blended silicone rubber raw materials, can effectively avoid the phenomenon of white out frost; 3, through the technical aspects of the blended silicone rubber raw material formula adjustment.
