Cumyl Peroxyneodecanoate (CIPP or CNP) is a key organic peroxide initiator that plays an irreplaceable role in the global polymer materials industry. With its molecular formula C₁₉H₃₀O₃ and molecular weight of 306.44, CIPP is a colorless transparent liquid known for its optimal half-life temperature range of 80–110 °C, ensuring efficient radical generation without excessive exotherm or runaway polymerization. Compared with benzoyl peroxide, it offers longer pot life, better storage stability, and lower volatility, making it ideal for high-clarity and color-sensitive resin systems.

PVC Polymerization:

• CIPP dominates the PVC sector as one of the most efficient low-temperature initiators. It enables high conversion rates, uniform particle size, and reduced fouling during suspension and emulsion polymerization. The initiator works effectively at 40–60 °C and is often used in combination with di-(2-ethylhexyl) peroxydicarbonate (EHP) at ratios of 1:3–1:4, diluted to 5–15 % with water and stabilized by PVA solutions. Such blends ensure smooth polymerization, even heat release, and improved safety in large-scale continuous operations.

Rubber Vulcanization:

• In elastomer cross-linking, CIPP serves as a low-temperature peroxide curing agent suitable for EPDM, NBR, HNBR, and silicone rubber. It provides superior heat and chemical resistance compared to sulfur vulcanization. However, because of its relatively low decomposition temperature (38–75 °C), it is mainly used for low-temperature or auxiliary curing formulations.

Coatings and Unsaturated Polyester Resins:

• CIPP delivers high efficiency in curing unsaturated polyester resins (UPR) and thermosetting coatings. It generates radicals at moderate or even ambient temperatures, reducing residual monomers while enhancing gloss and mechanical strength. Typical formulations combine 100 parts UPR with 1–3 % CIPP and 0.5–3 % cobalt naphthenate as a promoter, achieving fast and complete cure. In advanced composites, its low-temperature decomposition improves surface quality and transparency.

New Energy Materials:

• The use of CIPP has expanded rapidly in photovoltaic (PV) materials. In EVA encapsulant films for solar cells, CIPP acts as a crosslinking agent at 0.3–1.0 parts per 100 parts EVA. It ensures uniform crosslink density, high transparency, and long-term stability. Blends of CIPP with other peroxides—such as bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane or tert-butyl peroxycarbonates—allow precise control of curing kinetics and mechanical properties. The technology is also applied to battery insulation, charging system materials, and other energy storage components.

Other Polymer Fields:

• Beyond PVC and EVA, CIPP is also employed in LDPE (130–170 °C high-pressure polymerization) and PS polymerization for high optical transparency. Its volatile and low-residue decomposition behavior ensures colorless, odor-free resins suited for optical-grade and specialty plastics.
