Is it better to use PP board or PE board for plastic hot water tank?

The plastic water tank made of PE material is usually translucent white waxy, which is what people usually call milky white, without gaps, one-time molding by rotational molding, and good sealing performance. In addition, the whole water tank has no smell, non-toxic, and easy to clean. , light weight, good flexibility, flexible handling, easy to use. The plastic water tank made of PE material has good physical properties and chemical stability, as well as low temperature resistance, acid and alkali resistance, but its corrosion resistance to strong oxidation is relatively poor, and its melting point is relatively low.

The plastic water tank made of PP material is the lightest among all plastic water tanks, and the heat resistance is also the best. In addition, the plastic water tank made of PP material is non-toxic and tasteless, has good toughness, stable chemical properties, and strong gas barrier properties. Absorbent bottom with good insulating properties. However, it is relatively soft, easy to shrink, brittle, soft, and aging quickly. The service life is short, and it cannot be in contact with hot metal for a long time.

Generally speaking, the water tank made of PP material has better performance than the plastic water tank made of PE material, but the cost performance is poor, the service life is short, and the price is relatively expensive.

Through the above simple comparison, we can easily see that the plastic water tank made of PE material has stable chemical properties, good mechanical properties, and good rigidity and toughness, no matter in terms of performance or cost performance considerations. , strong adaptability to the environment, non-toxic and tasteless, harmless to the human body. PE material has been recognized by the industry as an environmentally friendly plastic water tank, and it is an ideal plastic container at present. Of course, you can also choose a water tank made of a suitable material according to your own needs.

Advantages of food-grade plastic water tanks :

1.PE plastic has strong corrosion resistance and does not react with acids and alkalis.

2. The plastic water tank is light in weight. The transportation and installation of large plastic water tanks do not require large hoisting equipment, and the cost is low. 

3. Durable, anti-aging, anti-oxidation, light weight. 

4. It is easy to be molded into different shapes. 

5. It is a good insulator without electrochemical corrosion.
