Foam silicone rubber is mainly divided into the double 24 vulcanization system and the platinum vulcanization system. Due to the different production processes, the products made from them naturally have slight differences. However, one thing is certain: among these two systems, there is definitely one process that is non-toxic and harmless; otherwise, how could there be the claim of food-grade foamed rubber?
This type of product, the bis-4 vulcanized foamed silicone rubber strip, has a slight odor and is mainly used in industry. It does indeed release a little toxic substances. Respecting facts is part of our Miura culture. However, since it is applied in industry and does not come into contact with the human body, there is no problem with this type of product. The volatilization of toxic and harmful substances in this process will not affect the human body. It can meet the testing and certification requirements of ROHS, REACH and other projects, which means that the volatile substances of the double 24 vulcanized foaming silicone rubber strip are below the international level of toxic and harmful volatile substances.
Summary: Industrial-grade silicone foam strips may contain slightly toxic and harmful substances, but they comply with international standards and can be manufactured and sold. They should not be in long-term indirect or direct contact with the human body.
Platinum vulcanized foamed silicone rubber strips are also known as food-grade foamed silicone rubber strips. They comply with international requirements such as ROHS and FDA, and are mainly used for sealing and waterproofing in household appliances (rice cookers, kettles, juicers, etc.). This process does not release any toxic or harmful substances throughout the entire manufacturing process, from raw materials to production The finished product is not only beautiful and attractive but has already obtained FDA certification, which can enhance the display of test reports.
Summary: Platinum vulcanized foamed silicone rubber strips are non-toxic and harmless. They can come into direct or indirect contact with the human body without any impact
