Q1: How to determine the proportion of vulcanizing agent added?
A: Adjust according to the hardness of the raw material, such as 0.8% for 30°A, 1.8% for above 80°A
Q2: What might be the reason for the incomplete vulcanization?
A: Contact with nitrogen/phosphorus containing substances, incompatible color glue or too high temperature (＞50℃).
Q3: Does it need to be stored in a refrigerator?
A: No need to refrigerate, just store at ≤30℃.
Q4: Which vulcanization processes are suitable?
A: Molding, extrusion and calendering are all available, with a temperature range of 140-550℃.
Q5: Why do black products require special colored glue?
A: Ordinary black pigments may inhibit the activity of platinum, resulting in incomplete vulcanization.
