High Rebound Property Raw Silicone Rubber , Sedex Authorized Baby Spoon Silicone
LFGB/FDA Approval Raw Material Sedex Authorized Manufacture Baby Spoon Silicone
Description
Liquid silicone rubbers are pumpable two-part compounds that are delivered ready to use. They are vulcanized by addition curing.
Component A contains catalyst and component B functional polysiloxane as a curing agent.
Compared to peroxide curing, liquid silicone rubbers do not release any curing by-products.

Performance Testing
RUI - HE Silicone has an extensive quality control system that tests the quality of raw materials first. The material cannot be used unless they are tested and meet our quality control standards. If it does not pass our incoming quality control testing, the material is refused and trucked back to the manufacturer.
Second, during the producing process, our quality control group will test the new batch of compound silicone rubber by taking some samples (twice from solid silicone rubber or three times from liquid silicone rubber) from different steps in the process. After passing the test, this batch can be sealed to pack and deliver to the customers.
FAQ
