What are the characteristics of PPnon-woven fabrics

(1) Weather resistance: Non-woven fabrics are very sensitive to ultraviolet rays, and the addition of zinc oxide dilauryl thiopropionate, and milky white fillers similar to carbon black can improve its aging resistance.

(2) Physical properties: PPnon-woven fabric is a non-toxic, odorless, milky-white high-crystalline polymer. It is one of the lightest varieties of all plastics at present. It is particularly stable to water. The water absorption rate in water for 14 hours is only 0.01. %. The molecular weight is between 80,000 and 150,000, and the formability is good. However, due to the large shrinkage rate, the original wall products are easy to dent, the surface gloss of the products is good, and it is easy to color.

(3) Mechanical properties: PPnon-woven fabrics have high crystallinity and regular structure, so they have excellent mechanical properties, and their strength, hardness and elasticity are higher than those of high-density PE (HDPE). The outstanding feature is the bending fatigue resistance (7×10^7) times of opening and closing, and no damage marks. The dry friction coefficient is similar to that of nylon, but it is not as good as nylon under oil lubrication.

(4) Thermal properties: PPnon-woven fabrics have good heat resistance, the melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃. Under the action of no external force, it will not deform at 150 °C. The embrittlement temperature is -35 °C, and embrittlement occurs below -35 °C, and the heat resistance is not as good as PE.

(5) Chemical stability: PP non-woven fabric has good chemical stability. In addition to being eroded by acid, it is relatively stable to other chemical reagents, but low molecular weight aliphatic hydrocarbons and aromatic hydrocarbons can make PP non-woven fabrics stable. The cloth softens and swells, and the chemical stability increases with the increase of crystallinity. Therefore, PP non-woven fabrics are suitable for making Russian-Chinese chemical pipelines and accessories, and have good anti-corrosion effects.

(6) Electrical properties: non-woven fabrics have excellent high-frequency insulation properties. Since it hardly absorbs water, the insulation properties are not affected by humidity, have a high dielectric coefficient, and can be used to make heat-resistant The electrical insulation products are also high in breakdown voltage, suitable for electrical accessories, etc. It has good resistance to voltage and arc, but has high static electricity, and it is easy to age when it is in contact with copper.
