Shuangxin PVA
Overview
PVA , categorized as a polyvinyl alcohol (PVA), is produced through an alcoholysis
reaction and subsequent polymerization of vinyl acetate. This material manifests as
a white, powdery substance, characterized by stability and non-toxicity, and it
exhibits remarkable water solubility. When introduced to water at room temperature,
it readily dissolves to create a stable colloid.

Firstly, each polyvinyl acetate is made by solution polymerisation, and then the
resulting polyvinyl acetate is hydrolysed rapidly in methanol, ethanol or a
mixture of ethanol and methyl acetate using alkali metal or acid-free as a
catalyst. Alcoholysis is carried out to obtain polyvinyl alcohol |
Frequently Asked Questions
Introduction
Inner Mongolia Shuangxin Environmental Protection Materials Co.,
Ltd., founded in June 2009, has been committed to integrated operations since its
inception. Adhering to the green and sustainable development philosophy, the Company has
consistently strengthened technological research and development, continuously extending
towards high value-added downstream applications of PVA. It has established a circular
economy industrial chain centered on polyvinyl alcohol (PVA),
encompassing limestone, calcium carbide, vinyl acetate,
polyvinyl alcohol, and downstream products such as specialty polyvinyl alcohol fibers. Today, Shuangxin Environmental
Protection has emerged as a significant player in the domestic polyvinyl alcohol and related
upstream and downstream industries.
Development
In June 2009, the groundbreaking ceremony for the PVA Circular Economy Industrial Base of
Inner Mongolia Shuangxin Environment-Friendly Material Co., Ltd. marked a significant
milestone. By 2014, the company's polyvinyl alcohol (PVA) series products had earned the
prestigious title of "Inner Mongolia Famous Brand Product." In 2018, the company's annual
production capacity of 130,000 tons of polyvinyl alcohol and 30,000 tons of special fibers
was recognized as a strategic emerging industry. Furthermore, in 2021, Shuangxin
Environmental Protection Company was awarded the title of "13th Five-Year Plan Technological
Innovation Demonstration Enterprise" in China's chemical fiber industry. In the same year,
the company's polyvinyl alcohol and high-strength, high-modulus polyvinyl alcohol fiber
products were honored with the "China Export Brand" status by the China Council for the
Promotion of International Trade (CCPIT).
