The influence of industrial formaldehyde as a by-product in the plastic manufacturing process on the properties of plastics
Published Time：
2025-12-11
The by-products generated during the production of plastics from industrial formaldehyde (such as free formaldehyde, free monomers, small molecule inorganic substances, oligomers, etc.) can significantly affect the mechanical properties, thermal properties, weather resistance, stability and safety of use of plastics through residual, reaction interference, and structural damage methods.
The by-products generated during the production of plastics from industrial formaldehyde (such as free formaldehyde, free monomers, small molecule inorganic substances, oligomers, etc.) can significantly affect the mechanical properties, thermal properties, weather resistance, stability and safety of use of plastics through residual, reaction interference, and structural damage methods. The degree of influence is closely related to the type of by-product, residual amount, and the type of plastic substrate. In most cases, it has a negative effect, and only a few can achieve a slight positive auxiliary effect through process control.
