Methyl methacrylate

Sourced in China

Methyl methacrylate is a clear, colorless liquid chemical compound with a characteristic pungent odor. It is a reactive monomer that can be polymerized to form polymethyl methacrylate (PMMA), a transparent thermoplastic material. Methyl methacrylate is commonly used as a raw material in the production of various laboratory equipment and materials.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
