Polypropylene high-strength yarn has these properties:

1. Form: The longitudinal surface of polypropylene high-strength yarn is straight and smooth, and the cross section is round.

2. Density: The advantage of polypropylene high-strength yarn is its lighter texture.

3. Tensile strength: polypropylene high-strength yarn has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance. The wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables.

4. Hygroscopicity and dyeability: light weight and good warmth retention.

5. Acid and alkali resistance: Polypropylene high-strength yarn has good chemical resistance, so it is suitable for use as filter materials and packaging materials.

6. Polypropylene high-strength yarn has good electrical insulation.

7. High strength: good abrasion resistance and good chemical stability.
