PP spunbond non-woven fabric is a new type of environmentally friendly material that can be used in different occasions according to its characteristics.
PP spunbond non-woven fabric is a non-toxic, odorless, milky white, highly crystalline polymer. It is one of the lightest varieties of all plastics. It is particularly stable to water, with a water absorption rate of only 0.01% for 14 hours in water. .
The molecular weight is about 80,000 to 150,000, and the formability is good.
However, due to the large shrinkage rate, the original wall products are easy to dent, and the surface of the products has good gloss and is easy to color.
The material has high crystallinity and regular structure, so it has excellent mechanical properties. Its strength, hardness, and elasticity are higher than high-density PE (HDPE).
The outstanding feature is the bending fatigue resistance (7×10^7) times of opening and closing bending without damage marks. The dry friction coefficient is similar to nylon, but not as good as nylon under oil lubrication.
In addition, spunbond non-woven products have excellent mechanical properties, and their tensile strength, breaking elongation, tear strength and other indicators are better than dry, wet and melt-blown non-woven fabrics, especially in recent years. The rapid development of the spunbond method in terms of production line scale, technology and equipment, and product market development has greatly expanded the application fields of spunbond non-woven fabrics.
Suzhou ptfe filter membrane manufacturer supplies imported pp spunbond non-woven fabrics. The company can provide samples and arrange sales personnel for door-to-door service if there are other requirements.
