Sealing pipe manufacturers believe that PVC pipes can be divided into soft PVC and hard PVC. Hard PVC accounts for about two-thirds of the market, while soft PVC accounts for about one-third of the market. Soft PVC pipes are usually used on floors, ceilings, and leather surfaces, but due to the presence of plasticizers (which is also the difference between soft PVC and hard PVC), their physical properties are very poor (such as water pipes that need to withstand a certain water pressure), and soft PVC is not suitable for use, so its application range is limited.

Sealing pipe manufacturers believe that hard PVC does not contain plasticizers, is easy to form, has good physical properties, and has great development and application value. In the production process of PVC materials, various additives such as stabilizers and plasticizers need to be added.

The sealing pipe manufacturer believes that the advantages of PVC pipes are:
1. Good tensile and compressive strength: However, its flexibility is not as good as other plastic pipes.
2. PVC pipe has low fluid resistance: The PVC pipe wall is very smooth, with almost no fluid resistance. Its roughness coefficient is only 0.009. Its water delivery capacity is 20% higher than that of cast iron pipes of the same diameter and 40% higher than that of concrete pipes.
3. Excellent corrosion resistance and chemical resistance: PVC pipes have excellent acid resistance, alkali resistance, and corrosion resistance, and are not affected by wet water and soil acidity and alkalinity. There is no need for anti-corrosion treatment when laying pipelines.
4. Good water tightness: The sealing pipe manufacturer believes that the installation of PVC pipes has good water tightness, whether connected by bonding or rubber rings.
5. Anti bite: The sealing pipe manufacturer believes that PVC pipes are not a source of nutrition and will not be corroded by rodents. According to a test conducted by the Michigan National Health Foundation, mice do not bite PVC pipes.
6. Performance testing: curing time, shrinkage rate, splitting strength, tensile performance, peel strength, thermal stability, shelf life, storage period, and release of harmful substances.
