Polymer Production
We help make polymers and improve their properties with high-quality initiators, catalysts, and specialty additives trusted by manufacturers worldwide.
Shandong Do Sender Chemicals Co., Ltd. provides essential chemistry for the polymer production industry. Our comprehensive portfolio of organic peroxides, azo initiators, and polymer additives supports the full spectrum of polymerization processes — from free-radical initiation to controlled molecular-weight regulation.
With deep expertise in peroxide chemistry and a vertically integrated supply chain, we deliver consistent quality, responsive technical support, and reliable logistics to polymer producers across Asia, Europe, and the Americas.
Main applications
PVC Production
High-efficiency initiators for suspension, emulsion, and bulk PVC polymerization. Our peroxydicarbonates and azo initiators deliver consistent reaction kinetics and excellent resin properties.
LDPE Production
Reliable organic peroxide initiators for low-density polyethylene (LDPE) autoclave and tubular processes. Tailored formulations for optimal conversion rates and polymer quality.
Product categories
Organic Peroxides
A full range of diacyl peroxides, peroxydicarbonates, peroxyesters, dialkyl peroxides, and hydroperoxides for free-radical polymerization.
Azo Initiators
AIBN, ABVN, and other azo compounds offering predictable decomposition kinetics for acrylics, polystyrene, and polyolefin production.
Polymer Additives
Chain-transfer agents, crosslinking co-agents, antistatic agents, and processing aids designed to fine-tune polymer performance.
