High-purity chemical precursors and raw materials sourced for global manufacturing applications.
In the contemporary landscape of polymer production and specialty chemical synthesis, Maleic Anhydride (commonly referred to in purchasing circles as Anhydride Maleic) stands as a crucial acid anhydride. Represented by the chemical formula C4H2O3, this highly reactive compound serves as a primary building block for the synthesis of Unsaturated Polyester Resins (UPR), alkyd resins, food-grade additives, and specialty co-polymers. For procurement managers scouting the globe for high-quality, high-purity stock at competitive rates, understanding the delicate balance between quality assurance and cost-effective bulk sourcing is essential.
When selecting discount Anhydride Maleic suppliers, chemical grade purity is the primary metric of concern. Shandong Pulisi Chemical Co., Ltd. ensures that all industrial batches maintain a minimum purity of 99.5% with extremely low moisture and maleic acid impurity content. The crystallization point is rigorously maintained above 52.5°C, indicating a high-density, crystalline product that minimizes agglomeration during transport and warehousing. Our quality protocols are backed by global certifications including ISO 9001:2015, SGS analysis, and compliance audits from third-party inspectors like Bureau Veritas (BV).
China is a primary global source of high-purity chemical raw materials. Chinese factories achieve efficiency through large-scale operations, highly integrated upstream chemical feedstocks, and strategic infrastructure. Shandong Pulisi Chemical Co., Ltd. utilizes integrated manufacturing networks and raw material supply agreements to insulate partners from sudden price shocks. Advanced automated processing units reduce conversion costs, enabling us to offer competitive wholesale pricing without compromising on product quality.

Maleic Anhydride is a versatile intermediate utilized across diverse manufacturing sectors.
The industrial demand for Anhydride Maleic is heavily driven by its role in producing Unsaturated Polyester Resins (UPR). UPR is utilized in glass-reinforced plastics for the automotive, marine, and construction industries. Additionally, Maleic Anhydride is an essential precursor for the synthesis of 1,4-Butanediol (BDO), which is a key component in the production of biodegradable plastics such as polybutylene adipate terephthalate (PBAT) and polybutylene succinate (PBS). As global regulations shift toward eco-friendly packaging materials, the demand for BDO and its precursors is projected to grow.
Another emerging application is in the production of lubricating oil additives. Dispersants and viscosity index improvers formulated from Maleic Anhydride derivatives help improve the efficiency and lifespan of modern internal combustion engines and industrial machinery. In agriculture, Maleic Anhydride derivatives are used in the formulation of selective herbicides, plant growth regulators, and soil conditioners, demonstrating the compound's utility across multiple sectors.
