The Perodox Origin Story
Perodox is the registered trademark for Shandong Do Sender Chemicals’ full line of organic peroxides. The brand was established in 2009 with a single product — dibenzoyl peroxide (BPO) — manufactured in a 500-square-meter workshop in Zibo, Shandong Province. Fifteen years later, Perodox encompasses over 40 organic peroxide formulations shipped to more than 80 countries, making it one of the most recognized Chinese organic peroxide brands in the global polymer industry.
The name “Perodox” combines peroxide with paradox — a nod to the dual nature of these molecules: highly reactive yet stable when properly formulated, dangerous when mishandled yet indispensable to modern materials science. This philosophy of mastering controlled reactivity has guided every product development decision since day one.

What Makes Perodox Different
Batch-to-Batch Consistency
Every Perodox product is manufactured under distributed control system (DCS) automation with in-process SPC (statistical process control). Active oxygen content is monitored in real time during synthesis, and every batch undergoes a 12-point quality check before release. The result is a coefficient of variation under 0.5% across production lots — a critical requirement for polymerization processes where initiator variability directly impacts polymer molecular weight distribution.
Custom Formulation Capability
Beyond standard grades, the Perodox R&D team develops custom formulations for specific customer processes. This includes phlegmatized (desensitized) grades with tailored phlegmatizer ratios for safer handling, polymer masterbatch dispersions for rubber and elastomer applications, and low-temperature initiator blends optimized for specific reactor residence-time profiles.
Safety-First Manufacturing Philosophy
Perodox production facilities incorporate multiple layers of engineered safety: temperature-controlled reactors with redundant cooling, explosion-proof electrical classification throughout production zones, continuous organic vapor monitoring with automated shutdown interlocks, and dedicated on-site emergency response teams trained to NFPA and Chinese GB standards. This commitment earned Do Sender Chem the 2025 ICCA Responsible Care Award for safety excellence.
The Future: 2026 and Beyond
With a growing global demand for organic peroxides driven by renewable energy infrastructure (solar encapsulants, wind turbine blade composites), electric vehicle battery materials, and sustainable packaging, Do Sender Chem is investing in a third production line scheduled for completion in late 2026. This expansion will double Perodox output capacity while incorporating next-generation process analytical technology (PAT) for real-time quality assurance.
“We started with one product and a simple belief that Chinese chemistry could compete globally on quality, not just price,” says the company’s founding team. “Fifteen years later, Perodox is proof that belief was right.”
