| Weathering resistance | Slightly weakened and it turns into yellow | Slightly weakened | It is sensitive to ultraviolet radiation, has poor impact and is easy to ageing. It will embrittle at temperatures below - 35°C. | Aging resistance is poor, embrittlement temperature -70°C, easy photooxidation, thermal oxidation, ozone decomposition and degradation under ultraviolet irradiation. | |||||
| Acid resistance | 7% hydrochloric acid, 20% sulfuric acid,10% nitric acid strength has no effect,16% or more concentrated hydrochloric acid, concentrated sulfur Acid, concentrated nitric acid can be decomposed and dissolved. | 35% hydrochloric acid, 75% sulfuric acid, 60% nitric acid has no effect on strength. | Concentrated hydrochloric acid strongly concentrated sulfuric acid has little effect on its products. | Resistance to hydrochloric acid, hydrofluoric acid, formic acid phosphate, etc. at room temperature. Nitric acid and sulfuric acid have strong destructive effects. | |||||
| Alkaline resistance | At room temperature, 50% caustic soda solution and 28% ammonia solution had no effect on its strength. | At room temperature, 10% caustic sodium solution and 20% ammonia water had no effect on its strength, but when the concentration or temperature increased, it was destroyed. | High purity sodium hydroxide and concentrated ammonia have little effect on strength. | Amine-resistant, sodium hydroxide, potassium hydroxide and other chemical materials. | |||||

| Solvent resistance | It is insoluble in most organic solvents,but soluble in phenols (phenols,mcresol, etc.), formic acid,expanded in glacial acetic acid,and can be dissolved by heating. | Insoluble alcohol,sky ether,acetone decomposition.It dissolves in ethane cyclohexanone, tetrachloride,lubricating oil, tetrahydronaphthalene,xyl ene and toluene when heated. When benzene is heated, it expands. | Insoluble alcohol,sky ether,acetone decompositi on.It dissolves in ethane cyclohexanone, tetrachloride,lubricating oil, tetrahydronaphthalene,xyl ene and toluene when heated. When benzene is heated, it expands. | It is insoluble in any known solvent at room temperature. It can be dissolved in toluene, amyl acetate, trichloroethylene and other solvents in a small amount at above 70 C. Mineral oils, vaseline, vegetable oils and fats can swell it and cause permanent local changes in its physical properties. | |||||
| Dyeing resistance | Acid dyes,disperse dyes ,reactive dyes,dyeable, good color fastness. | Available dispersing dyes, naphthol dyes Dip or heating dye. | Disperse dyes direct dyes | Low temperature disperse dye, stock solution dyeing, methyl yellow dye | |||||
