Prevent thermal degradation and provide long term stability

Antioxidants help preserve the appearance and physical properties of polymers. Ampacet offers two categories of antioxidants, each with a specific function in polymer stabilization:

Primary antioxidants are used to protect the finished product. This ensures performance over the life of the finished good. The typical chemistry is phenolic-based.

Secondary antioxidants are used as process stabilizers. They protect the polymer during processing, especially when the polymer undergoes multiple heat histories. Typical chemicals employed include phosphites and thioesters.

Primary/Secondary blends are often used to protect the polymer in the processing step and throughout its service life.

To avoid pinking or yellowing, proper selection of antioxidants and co-additives is required. Click here for more detail.
