Silicone rubberWhat are the common quality issues with double vulcanization, and what are the solutions when problems arise?
1. Silicone rubber cracking and bubbling: Excessive volatile emissions or hidden air inside the vulcanized products during shaping.
Solutions: Adjust the gradual heating conditions and slow down the heating rate; also, inspect the reclaimed rubber material to remove air bubbles.
2. Silicone rubber has a significant degree of compression deformation: insufficient vulcanization or inappropriate selection of rubber compound formula.
Solutions: Extend vulcanization time in the oven; increase air circulation; reduce the number of products placed inside; check the oven temperature; select rubber materials with minimal compression deformation.

3、Silicone rubberOver-hardening: Overheated oven curing
Solution: Verify the temperature at each part of the oven; check and inspect the temperature control system.
4. Silicone rubber hardness too low: Unreleased gas not fully expelled from the oven
Solutions: Check the oven's ventilation; verify the oven temperature.
