Under the background of technological innovation of wind turbine blade main beams, methyltetrahydrophthalic anhydride (MTHPA) faces huge development opportunities

Methyl tetrahydrophthalic anhydride (MTHPA), generally methyl tetrahydrophthalic anhydride, is an organic solvent with the molecular formula C9H10O3 and is liquid at room temperature. Methyl tetrahydrophthalic anhydride has the characteristics of low volatility, low melting point, low toxicity, low volatility, excellent insulation performance and process performance of the cured product, and is one of the main derivatives of maleic anhydride. Methyltetrahydrophthalic anhydride has a wide range of uses, including electronics, medicine, dyes, spices, cosmetics, paints, coatings, inks, electroplating, etc.

The upstream of the methyltetrahydrophthalic anhydride industry chain is raw material suppliers such as mixed C5 petroleum resin, piperylene solution, maleic anhydride, quinone, and nickel-based catalysts; the midstream is Puyang Huicheng, Qingyang Chemical, and Alpha Chemical , Wuhan Rongcan Biotechnology, Wanshixing Chemical Industry, Shandong Qingyang New Materials and other methyltetrahydrophenic anhydride preparation and processors; downstream are pharmaceuticals, coatings, inks, electronics, electroplating and other application fields.

In recent years, under the background of the rapid development of the domestic wind power industry, the trend of large-scale wind power blades has been continuously highlighted, and the requirements for the strength, stiffness, lightweight and other aspects of the blades have continued to increase. Compared with the current infusion molding process used for wind turbine blade main beams, the pultrusion molding process has higher fault tolerance, resource utilization, production efficiency and better structural performance. In the future, it will replace the traditional infusion molding process and become the mainstream of wind turbine blade main beams. Molding technology has become the general trend. The main choice of curing agent for pultruded main beams is methyltetrahydrophthalic anhydride. In the future, methyltetrahydrophthalic anhydride will develop rapidly driven by the wind power pultruded main beam industry.

According to the “2022-2027 Methyl Tetrahydrophthalic Anhydride (MTHPA) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center 》 Shows that at this stage, the domestic effective production capacity of methyltetrahydrophenic anhydride is close to 90,000 tons. 2021 is the first year for the pultrusion molding process of the main beam of wind turbine blades to replace the traditional infusion molding process. In the future, against the background of the increasing installed capacity of domestic wind power, the market demand for methyltetrahydrophenic anhydride will continue to increase. It is expected that by 2023, the domestic A The effective production capacity of tetrahydrophthalic anhydride will increase to 130,000 tons, and the industry has huge development potential.

Industrial analysis personnel said that at this stage, the number of domestic methyltetrahydrophenic anhydride manufacturers is still relatively small, such as Puyang Huicheng, Qingyang Chemicals, Alpha Chemicals, etc. are currently leading companies in the industry. Methyltetrahydrophenic anhydride has high customer barriers. Downstream wind power customers will not easily change their suppliers after testing and certification. Companies that enter the wind turbine blade main beam market first in the future will have a first-mover advantage. Therefore, domestic Methyltetrahydrophenic anhydride companies also need to continuously improve their core competitiveness and seize the opportunity in the wind turbine blade main beam market. In the future, under the background of rapid innovation in domestic wind power main beam processing technology, the methyltetrahydrophthalic anhydride industry will usher in huge development opportunities and the industry has huge development potential.
