How does detergent affect the oil absorbency rate of Polypropylene Pads?

1 2 3 4 5

The purpose of this experiment is to investigate how various detergents affect the absorbency rate of polypropylene pads.

Hypothesis

Detergent decreases the ability of polypropylene pads to absorb oil spills.

Overview

What is Polypropylene?

Polypropylene is a durable type of plastic that can withstand wear and tear. It is widely used in the manufacture of packaging materials, food containers, roofing materials, loudspeakers, furniture, piping and other forms of products that require durability and strength. It is a strong material and it is generally resistant to many chemicals, acids and bases.

Here, polypropylene is used to make oil-absorbent sheets which can be used to soak up oil spills and leaks.
