How can you tell if a film is PVC?

PVC has an acrid smell like chlorine, so stay away from the smoke and gas given off by PVC. LDPE and HDPE smell like candle wax, while Polypropylene smells similar to candle wax, but with an element of paraffin to it. ABS and polystyrene both smell like styrene, but the ABS also has a faint rubbery smell to it.

How do you test plastic material?

Plastic Testing (Polymer Testing)

1. Testing plays a critical role in the life cycle of a polymer, from the raw material to the compound through to the semi-finished and finished product.
2. Impact Testing – Drop Tower.
3. Impact Testing – Pendulum.
4. Tensile Testing.
5. Rheology.
6. Thermal Testing.
7. Thickness Testing.
8. Friction Testing.

How is PE made?

Polyethylene (PE) is a made by the reaction of multiple ethylene molecules in the presence of catalyst to break the double bond and connect the carbon atoms into a chain (Figure 1). The longer the chain, the higher the molecular weight. Polymers can have molecular weights in the millions.

What is the difference between PP and PE?

Polyethylene (PE) is tough yet light, with good resistance to impacts and abrasions. On the other hand, Polypropylene is harder and can be used for mechanical and structural applications. Polypropylene is stiffer and more chemical-resistant and scratch-resistant, while still being very tough.
