Bis(tert-butylperoxyisopropyl)benzene (BIPB)
BIPB | Odorless DCP | Crosslinking Agent for PE / EVA / Rubber
Product Description
Bis(tert-butylperoxyisopropyl)benzene (BIPB) is a highly efficient organic peroxide crosslinking agent widely used in rubber and plastic processing.
Compared with traditional DCP (Dicumyl Peroxide), BIPB offers lower odor, higher crosslinking efficiency, and improved processing performance.
Under the same crosslinking effect, the required dosage of BIPB is approximately 2/3 of DCP, which can effectively reduce formulation cost and improve the odor of final products.
BIPB is especially suitable for indoor wire insulation materials and EVA foaming products.
