The Common Properties Of Pp Spunbond Non Woven?

PP spunbond non woven is one of many types of non-woven fabrics. It is made of polypropylene (pp material), which is polymerized into a net after high-temperature drawing, and then bonded into a non-woven fabric by hot rolling. PP spunbonded non-woven fabric is widely used in various fields such as medical treatment and sanitary materials because of its simple production process, large output, and non-toxic and harmless to the human body. This article briefly introduces the commonly used properties of pp spunbond non woven, in order to provide reference for related research.

1. Physical properties

PP spunbond non woven is a non-toxic, odorless milky white high crystallization polymer. It is one of the lightest varieties of plastics at present. It is especially 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.

2. Mechanical properties

PP spunbond non woven has high cleanliness and regular structure, so it has excellent mechanical properties, and its strength, hardness and elasticity are higher than high-density PE.

3. Thermal performance

PP spunbond non woven has good heat resistance, the melting point is 164-170 ℃, and the product can be sterilized at a temperature above 100 ℃.

4. Chemical stability

PP spunbond non woven has good chemical stability, except that it can be corroded by acid, it is relatively stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell pp spunbond non woven, chemically stable The performance is improved with the increase of cleanliness. In summary, this article introduces the physical properties, mechanical properties, thermal properties and chemical stability of pp spunbond non woven, which are its commonly used properties.
