The spiral hose guard on the market are generally PP, PA and PE. So what’s the difference among them? Then let me analyze this for you below.
First, let’s take a look at the corrosion resistance, bending, heat resistance and price. Corrosion resistance: PA<PE≈PP. Bending: PA<PE<PP. Heat resistance: PE<PP<PA. Price: PE<PP<PA.
Which material is the best for a spiral hose guard?
First, PP has all the advantages of PE. Such as low price, wide range of uses, good corrosion and wear resistance. Besides, common acid and alkali organic solvents are almost insoluble in it. PP has the smallest density among all plastics and has strong bending resistance. It is known as “100-fold rubber” and can be soaked in boiling water at 100℃ without deformation or damage.
Second, PA nylon has good wear resistance and heat resistance, and its max temp resistance can reach 150℃. However, the price of nylon is relatively high and it can not be in contact with acid and alkali for a long time. The nylon material is relatively hard, brittle, and difficult to bend.
Third, PE polyethylene plastic is cheap, saves usage, has stable chemical properties, and can resist corrosion by various chemical substances such as hydrochloric acid, hydrofluoric acid, phosphoric acid, sodium hydroxide, potassium hydroxide, etc. at room temperature. It has good air permeability and is often used to make daily necessities, but its tensile strength is low and its heat resistance is not strong.
Based on the characteristics of PE, PA, and PP, Hiteck chose PP as the raw material. It is self-produced and sold. The products produced have good corrosion resistance, strong bending resistance, and heat resistance. It has the advantages of excellent durability; at the same time, we have modified the polypropylene to make the spiral protective cover more wear-resistant and anti-aging.
