One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

Prof Matthew Wright, both a member of the FAF Panel and chair of EFSA’s working group on E 171, said: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
