Why SHENWEI BELTS have excellent shock resistance and high load capacity?
Agricultural machinery belt one of the most important raw materials: Kevlar & Polyester cord.
Kevlar is a plastic strong enough to stop bullets and knives—often described as being "five times stronger than steel on an equal weight basis.
It's strong but relatively light. The specific tensile strength of Kevlar is over 8 times greater than that of steel wire.
Unlike most plastics it does not melt: it's reasonably good at withstanding temperatures and decomposes only at about 450°C (850°F).
Kevlar can be ignited but burning usually stops when the heat source is removed.
Very low temperatures have no effect on Kevlar: "no embrittlement or degradation" down to −196°C (−320°F).
Like other plastics, long exposure to ultraviolet light (in sunlight, for example) causes discoloration and some degradation of the fibers in Kevlar.
Kevlar can resist attacks from many different chemicals, though long exposure to strong acids or bases will degrade it over time.
In DuPont's tests, Kevlar remained "virtually unchanged" after exposure to hot water for more than 200 days and its super-strong properties are "virtually unaffected" by moisture.
The advantages of cord as below:
1. Wear resistance, high temperature resistance, long service life
2. High strength and low elongation
3. Reduce maintenance, easy to install and use
