About MENGWEI
Sixteen Years of Polyurethane Chemistry, Engineered in Shanghai
Since 2010, MENGWEI has manufactured polyurethane systems, polyether polyols, additives, and specialty industrial chemicals from our Jinshan District facility — serving manufacturers, contractors, and distributors across more than twenty countries.
About MENGWEI
Our Story
Founded in 2010, Shanghai Mengwei Advanced Materials Co., Ltd. began with a focused vision: to build a polyurethane manufacturer that combined the technical depth of European chemistry leaders with the agility, scale, and partnership culture that international customers actually need from their supply chain.
Sixteen years later, our 186-person team operates dedicated production lines for rigid polyurethane systems, polyether polyols, PU additives, waterproofing coatings, and specialty industrial chemicals. We have grown without losing what made the company work in year one: every order is treated as a project, every customer is treated as a partner, and every formulation is delivered to specifications we put in writing.
Today, MENGWEI products leave our Shanghai facility for cold storage builders in Southeast Asia, waterproofing distributors in Latin America, sandwich panel manufacturers across the Middle East, MS sealant producers in Malaysia, mattress factories in Russia, and dozens of other customer types that demand consistent quality and responsive supply.
