Finally find information on the difference between High Density Polyethylene (HDPE) and PVC wicker! Although they are both plastics, the two differ in terms of strength, hardness, transparency. This discussion can go deeper into specifics but I’m going to sum it all up for you.
You can use this information when shopping for outdoor wicker patio furniture. Prices vary greatly on synthetic resin wicker sets and that’s largely because of the material used. To make sure you don’t wind up on the losing end, take a moment to read through this comparison of HDPE and PVC Synthetic wickers.
Comparing HDPE and PVC Wicker Strands
There are two types of plastics; thermoplastics and thermosetting polymers.
- Can be melted and molded repeatedly. This is why they are recyclable.
- Used to make bottles, plastic bags, wire insulation, pool toys, and containers.
- Can be melted and molded only once. Become solid when cooled.
- Several types of thermoplastics; either amorphous or semi-crystalline.
- PVC (polyvinyl chloride) is amorphous while HDPE is a semi-crystalline.
What is PVC?
PVC is a cheap vinyl polymer that is used to make pipes. It is the third most popular plastic following polyethylene (PE) and polypropylene (PP). Some of its key features are as follows:
- Lightweight and durable material.
- Low production cost.
- PVC is heavier and stronger in terms of pressure capacity (pipes).
What is High Density Polyethylene?
Also abbreviated as PEHD (Polyethylene High-Density), High Density Polyethylene is a polyethylene thermoplastic that is made from petroleum. HDPE offers more tensile strength, and intermolecular force. Tensile strength measures the force required to pull something apart as applied in wicker strands.
- Resistant to a variety of chemical solvents.
- Lighter, stronger, harder, and can withstand higher temperatures.
- Can withstand temperatures of 230 degrees Fahrenheit.
- Has absorptive characteristic that dampens vibrations.
- Has a higher Crystallinity than Polypropylene. Crystallinity influences hardness and density, hence the name High Density Polyethylene.
- Polyethylene is the most widely used plastic. Eco-friendly material that can be recycled!
- Used to make fireworks, wood plastic composites, water pipes.
HDPE is made from the catalytic polymerization of ethylene. Polymerization is achieved through suspension, gas, or solution-phase reactors. Comonomers (butane, octane, and hexane) are added to increase intermolecular force.
