Polypropylene short fibers (polypropylene raw materials for lifting belts) have strong micro reinforcement effects, which can maintain the integrity of the structure and avoid scattering into many fragments when the structure is damaged by impact. This is why polypropylene lifting belts/polyester lifting belts can be widely used in industrial/lifting and other stress situations, becoming a leader in lifting products.
Polypropylene short fibers are widely used not only in the lifting industry, but also in the construction industry, highlighting their obvious advantages. For example, when the content of polypropylene short fibers is 0.6 to 1.8 kilograms per cubic meter of mortar or concrete, the fiber content should be different. For areas with severe freeze-thaw cycles and areas with severe abrasion, the fiber content should be higher in order to be applied to the construction industry. Its excellent characteristics are maximized by modern construction.
Why does polyester/polypropylene fiber material have super strong load-bearing performance? Ultimately, it comes down to the physical properties of polyester/polypropylene fibers, which are as follows:
In its natural state, polyester/polypropylene fibers exhibit bundled single filament specifications, with diameters generally ranging from 3/5/8/15/19 (millimeters)
Specific gravity heavier than general synthetic materials: 0.91 (grams)
Tensile strength: greater than 400Mpa
Acid and alkali resistance: extremely high (compared to other chemical fiber products)
Elastic modulus: greater than 3.5Gpa
Melting point: approximately 160 degrees Celsius
Fiber diameter: greater than 48um
Thermal conductivity: extremely low
Ignition point: approximately 580 degrees Celsius
Moisture content: less than 0.1%
Safety: Non toxic materials
Low temperature resistance: no change in fiber properties detected by -78 degrees Celsius experiment
Aging resistance: the fiber has undergone special aging resistance treatment
By analyzing the performance of polyester/polypropylene fiber materials through the above 13 points, we can understand why white/colored lifting belts have played a crucial role in the lifting product industry for many years and are highly sought after by the public.
