Our PPH (Polypropylene Homopolymer) sheets are engineered from high-molecular-weight homopolymer polypropylene with a low melting flow index. By utilizing advanced Beta-modification technology, these sheets feature a uniform and fine Beta crystal structure, delivering a superior balance of chemical resistance, thermal stability, and creep resistance, while maintaining exceptional impact strength even in low-temperature environments.
Designed specifically for the most demanding industrial applications, PPH sheets are the ideal choice for fabricating corrosion-resistant equipment. They are widely deployed in chemical extraction, metallurgy, and electronics sectors—particularly for the construction of economical and durable pickling tanks and electrolytic tanks, significantly reducing maintenance costs and extending equipment service life.
