Properties of polypropylene
Polypropylene is a thermoplastic polymer that is polymerized from propylene monomer. It has the following characteristics:
1. Lightweight: Polypropylene has a lower density, usually 0.90-0.91 g/cm ³, and is lighter than water.
2. High strength: Polypropylene has excellent strength and stiffness, with a strength more than 30% higher than ordinary plastics.
3. Good heat resistance: Polypropylene has good heat resistance and can withstand high temperatures up to around 100 ℃.
4. Good chemical stability: Polypropylene is not easily corroded by chemicals and has a certain tolerance to chemicals such as acids, bases, and salts.
5. Good Transparency: Polypropylene has good transparency and can be used to make transparent containers and packaging materials.
Application of polypropylene in non-woven fabrics
Non woven fabric is a new type of textile that is widely used in fields such as healthcare, hygiene, environmental protection, agriculture, and construction due to its excellent breathability, waterproofness, softness, and wear resistance. As one of the main raw materials for non-woven fabrics, polypropylene has the following advantages:
1. Melt blown non-woven fabric: Polypropylene can be melted and made into non-woven fabric through melt blown technology, which has good strength and breathability, and is widely used in fields such as hygiene, medical care, and home furnishings.
2. Spunbond nonwoven fabric: Polypropylene can be processed into spunbond nonwoven fabric through spunbond technology, which has softness and good hand feel, and is widely used in medical, health, home and other fields.
Application of polypropylene in other fields
In addition to non-woven fabrics, polypropylene is also widely used in other fields, such as:
1. Plastic products: Polypropylene can be used to make various plastic products, such as plastic bags, plastic buckets, plastic bottles, etc.
2. Textiles: Polypropylene fibers have good wear resistance and breathability, and can be used to make sportswear, outdoor clothing, etc.
3. Automotive components: Polypropylene has excellent heat resistance and toughness, and can be used to make automotive interior parts, door panels, and other components.
Conclusion
In summary, polypropylene, as an important non-woven fabric material, has excellent physical properties and chemical stability, and is widely used in non-woven fabrics, plastic products, textiles, and other fields.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
