Difference Between HDPE and PVC

Polyvinyl chloride (PVC) is a cheap and durable vinyl polymer used in construction projects while high density polyethylene (HDPE) is a polyethylene thermoplastic that is made from petroleum. ... PVC is heavier and stronger while HDPE is harder and more abrasion and heat resistant.

Is HDPE stronger than PVC?

Both HDPE and PVC pipes are stronger throughout higher temperatures. ... PVC has a failure rating of 1 in 48,650 incidents, where HDPE is 1 in 10,000,000. This indicator shows that when exposed to extreme weather conditions, HDPE is proven to be more durable.

Is HDPE pipe cheaper than PVC?

W HDPE pipe is cheaper than PVC pipe. W HDPE laterals (the combined cost of pipe and fittings) are more expensive than PVC laterals. The cost of a HDPE fitting is higher than the equivalent PVC fitting. This is particularly true on Golf Course Irrigation System where the cost of good quality HDPE fittings is high.

Is PVC a HDPE?

PVC is a fairly durable vinyl polymer while HDPE is a thermoplastic made from petroleum. They are both considered plastics. When comparing failure ratings, PVC has shown to be higher than HDPE. PVC has a rating of one in 48,650 events compared to HPDE with one in 10,000,000.

Which is better PVC or plastic?

As far as its electrical properties, PVC has good insulation, but, because it has polar elements to its composition, it has worse insulation than other plastics, such as polyethylene and polypropylene. PVC is extremely chemical-resistant, able to withstand acids, salts, bases, fats, and alcohols.

Where is HDPE used?

HDPE is a Type 2 plastic commonly used in making containers for milk, motor oil, shampoos and conditioners, soap bottles, detergents, and bleaches.

Is HDPE waterproof?

Answer: Yes, HDPE is appropriate for building foundation waterproofing. In addition to helping waterproof, it can also act to help protect the foundation from root intrusion. When also acting as a root barrier, many customers upgrade to 30 mil. ... The tight cellular structure of HDPE makes it an effective vapor retarder.

What are the disadvantages of HDPE?

The Disadvantages of HDPE Include

• Poor Weathering.
• Highly Flammable.
• Sensitive to Stress Cracking.
• Not Biodegradable.
• Can't Be Composted.
• Not Resistant to Oxidizing Acids.
• Not Resistant to Chlorinated Hydrocarbons.
• High Thermal Expansion.

Why HDPE pipes are used?

HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.

Can you weld PVC to HDPE?

HDPE is common and cost effective conduit often used in directional boring. But PVC cement will not stick to HDPE at all. Mechanical coupling are available to compress or thread PVC to HDPE. But the strength and water tightness of the joint can be inconsistent.

What is the cost of HDPE pipe?

Questions & Answers on HDPE Water Pipe

What does HDPE stand for?

High Density Polyethylene. : HDPE is a hydrocarbon polymer prepared from ethylene/petroleum by a catalytic process.

Why is PVC strong?

The polymer is usually linear with not many branching points, but is still very strong due to the strong intermolecular forces. ... PVC usually has a high polymerization number; therefore, the POPs emitted from PVC are usually more toxic as they also have higher molecular weight and become insoluble in water (1).
