How silicone rubber products pass LFGB/FDA quality inspection

With the prevalence of silicone rubber products, the quality requirements for silicone rubber products are naturally high. In particular, some exported silicone rubber products have very strict requirements and need to undergo some tests and provide test reports, such as lfgb/fda, etc. So how do silicone rubber manufacturers make silicone rubber products pass lfgb and FDA quality tests? Silicone rubber products have passed lfgb and FDA testing methods:

After lfgb testing (FDA testing is relatively easy), silicone rubber products generally use vapor phase glue plus double 25 (platinum is added for higher requirements), and the post-processing is as follows:

1. Silicone rubber products generally require secondary sulfur addition for 8 hours.

2. If conditions permit, add sulfur twice for 6 hours, boil in water for 4 hours, and then continue adding sulfur twice for 2 hours.

Test precautions:

1. The silicone rubber products after treatment should be wrapped with tin foil at the first time, and avoid contact with air after measurement, because the adsorption of silicone rubber products will absorb water molecules in the air and affect the test results.

2. Due to the material of silicone rubber itself, it is difficult to pass the test of olive oil solvent, especially the colored silicone rubber products.
