Several properties analysis of polypropylene non-woven fabric

1. Physical properties: Polypropylene non-woven fabric is a non-toxic, odorless, milky white highly crystalline polymer with good formability. However, due to the large shrinkage rate, the original wall products are easy to dent, the surface of the products has good gloss and is easy to color.　　2. Mechanical properties: Polypropylene non-woven fabric has high crystallinity, regular structure, and its strength, hardness and elasticity are higher than high-density PE (HDPE).　　3. Thermal performance: Polypropylene non-woven fabric has good heat resistance, and the products can be sterilized at temperatures above 100°C. No deformation at 150°C under no external force. The embrittlement temperature is -35℃, embrittlement will occur below -35℃, and the heat resistance is not as good as PE. 4. Chemical stability: Polypropylene non-woven fabric has good chemical stability. In addition to being corroded by acid, it is relatively stable to other chemical reagents. Polypropylene non-woven fabric is suitable for making Russian-Chinese chemical pipelines and fittings, and has anti-corrosion effect. good.　　5. Electrical properties: Non-woven fabrics have excellent high-frequency insulation properties and can be used to make heated electrical insulation products. The breakdown voltage is also high, and they are suitable for electrical accessories. Good resistance to voltage and arc, but high static electricity, easy to aging in contact with copper.　　6. u200bu200bWeather resistance: Non-woven fabrics are very sensitive to ultraviolet rays. Adding zinc oxide thiopropionate dilaurin, carbon black-like milky fillers, etc. can improve its aging resistance. Quanzhou Non-woven Fabric Co., Ltd. is a manufacturer of non-woven fabrics in Quanzhou. It mainly produces flame-retardant non-woven fabrics, polypropylene non-woven fabrics, PP non-woven fabrics, coated non-woven fabrics, etc. The quality is reliable, please call for consultation and order!
