First of all, what is plastic?

What is plastic

It is a general term for organic polymer substances that can be softened by heating, molded into any shape, and have the property of not returning to their original shape (material plasticity). According to the JIS standard, it is defined as "A solid artificially formed into a useful shape using polymeric substances as the main raw material. However, fibers, rubber, paints, adhesives, etc. are excluded. (JIS K 6900)" It has been.
Because they are light, durable, and can be mass-produced, they are used in various fields of life.
In order to realize a sustainable society, Richell provides non-disposable plastic products that are durable and can be used for a long time.

Crude oil, which is an organic macromolecule (molecules composed mainly of carbon atoms with many atoms bonded together), is a fossil fuel that was created by chemically changing the remains of organisms such as plankton that were deposited on the ocean floor.

plastic production process

The main raw material for plastics is crude oil, but plastics are not made directly from crude oil, but are distilled, naphtha is extracted, and further fractionated, and plastic materials are made through a number of stages of processes. .
Plastics made from materials other than petroleum (grain starch, etc.) are also being mass-produced today.

Properties of plastic

Compared to metals, plastics have the following characteristics, and we manufacture products that take advantage of these advantages.
