On the importance of polypropylene cover of fall arrester

The reason why the fall arrester has such excellent performance is inseparable from each link of its own design, and one of them depends on its own clothes - shell. Everyone must know the function of the cover. We can't talk more. Today we mainly talk about the material of the fall protector cover.

Some manufacturers with more mature technology will adopt the protection mode of double shell. Generally speaking, the double shell includes the outer shell and the inner shell. The two shells complement each other and play an excellent protective role. The inner shell is generally made of alloy steel, and the shell is made of polypropylene.

There is no need to say more about the alloy steel shell. It is strong and resistant to manufacturing. What kind of material is polypropylene?

Polypropylene is a polymer made of propylene through addition polymerization. Polypropylene is a thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties. Because polypropylene has plasticity, polypropylene materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical function of metal.

From this, we can see that due to the strong characteristics of polypropylene material, the polypropylene shell of the fall arrester is not only difficult to damage itself, but also plays a protective role in the alloy inner shell, which is the importance of the fall arrester shell.
