What are PVC hoses, and why should you care? These versatile tools play a key role in industries worldwide.
From agriculture to automotive, PVC hoses are widely used for their flexibility and durability. In this post, we’ll explore what PVC hoses are, their benefits, and their growing popularity over the years.
PVC, or Polyvinyl Chloride, is a type of plastic used in various applications. It’s made from a polymer that is derived from vinyl chloride, a chemical compound. PVC can be both rigid or flexible, depending on how it is processed.
PVC hoses start with polymerization, a process where vinyl chloride is exposed to heat and light. This causes the individual molecules to bond together, forming long chains. These chains create a material strong enough to be used in hose manufacturing. The process can also involve additives to improve flexibility or durability, which is why some PVC hoses are more flexible than others.
PVC hoses are made from a combination of PVC resin, plasticizers, and stabilizers. The resin gives it strength, while the plasticizers make it flexible. Stabilizers prevent the hose from breaking down when exposed to heat or sunlight. Reinforced hoses may include a layer of fabric or steel braid for added strength and protection.
