English to Spanish Tech/Engineering Chemistry; Chem Sci/Eng N’N-diaryl-paraphenylene diamine mixture (DPPD)

Me encuentro con este término en el siguiente contexto:

N’N-diaryl-paraphenylene diamine mixture (DPPD) is an excellent dynamic antiozonant and a good antioxidant that provides long-term protection. It also protects against bin cure in CR. It provides excellent high temperature heat degradation resistance, good flex crack resistance and protects against copper degradation. Often used with the dialkyl and alkyl/aryl p-phenylene diamines to provide optimized short-term and long-term protection.

Aguardo su ayuda.

Desde ya, muchas gracias.

Saludos.
