Various common properties of PP non-woven fabrics!

(1) Physical properties

PP non-woven fabric is non-toxic, tasteless milky white high crystalline polymer, is currently one of the most light varieties of plastic, especially stable to water, in the water absorption rate of 14h is only 0.01%. Molecular weight of about 8-150,000, good formability. However, due to the large shrinkage rate, the original wall products are easy to sag, and the surface color of the products is good and easy to color.

(2) Mechanical properties

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

(3) Thermal performance

PP non-woven fabric has good heat resistance, melting point at 164-170 ° C, products can be sterilized at temperatures above 100 ° C. Under the action of no external force, 150℃ does not deform. The 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 being corroded by acid, other chemical reagents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc., can make PP non-woven fabric soften and swell, 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 heated electrical insulation products, breakdown voltage is also very high, suitable for electrical accessories and so on. Good voltage resistance and arc resistance, but high static electricity, easy aging in contact with copper.

(6) Weather resistance

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