Properties and Applications: DH-A is used to provide long term heat stability in sulfur vulcanized conpounds by substituting stable, flexible carbon-carbon crosslinks for the sulfur crosslinks that are destroyed by reversion in the mold or during product service life. It is used in most sulfur vulcanized polymers to provide improved reversion resistance on overcure. It is used to allow the use of higher curing temperature for improved productivity without sacrificing performance properties. It’s not reactive during the initial stages of vulcanization. Scorch and cure time are therefore not affected, thus to be added without making other compound or process modifications.
The recommended dosage:1-3 phr
Storage: Stored closely in a cool,dry,well-ventilated area.The storage life is 12 months.
Package: In 25kg paper bags with prastic inner.
