PP non-woven fabric of various commonly used properties!

(1) Physical properties

PP non-woven fabric is non-toxic, tasteless opalescence white high crystallization polymer, is currently many plastic most light varieties, especially stable to water, in the water absorption rate of 14h is only 0.01%. Molecular weight about 80-150 thousand, good formability. But because the shrinkage rate is large, the original wall products are easy to sag, the product surface color is good, easy to color.

(2) Mechanical properties

PP non-woven fabric has high cleanliness, regular structure, so it has excellent mechanical properties, its strength and hardness, elasticity are higher than high density PE. The outstanding characteristics are strong resistance to bending fatigue, dry friction coefficient is similar to nylon, but not as good as nylon under oil lubrication.

(3) Thermal performance

PP non-woven fabric has good heat resistance, melting point at 164-170℃, products can be sterilized at more than 100℃ temperature. Under the action of no external force, 150℃ does not deform. Embrittlement temperature is -35℃, and embrittlement will occur below -35℃, and the heat resistance is not as good as PE.

(4) Chemical stability

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 cleanliness and improve.

(5) Electrical properties

Non-woven high frequency insulation performance is excellent, because it is almost no water absorption, so the insulation performance is not affected by humidity, has a high dielectric coefficient, and with the rise of temperature, can be used to make hot electrical insulation products, breakdown voltage is also very high, suitable for electrical accessories. Good voltage resistance, arc resistance, but high electrostatic degree, easy to aging contact with copper.

(6) Weather resistance

Non-woven fabric is very sensitive to ultraviolet, adding zinc oxide dilauryl thiopropionate, carbon black similar milky white filler can improve its aging resistance.
