PP non-woven fabric has good chemical stability, in addition to acid erosion, other chemical reagents are relatively stable, but low molecular weight fatty hydrocarbons, aromatic hydrocarbons can make PP non-woven fabric softening and swelling, chemical stability with the increase of crystallinity has been improved.
Therefore, PP non-woven fabric is suitable for the production of Russian and Chinese chemical pipelines and accessories, corrosion prevention effect is good.
