About PVC, the material of Figure

When I can’t buy a figure, I’m going to research and write about things that usually bother me. This time, we’re going to talk about PVC, the material used to make figures.

About PVC

Polyvinyl chloride (/ˌpɒlivaɪnəl ˈklɔːraɪd/; colloquial: polyvinyl, vinyl; abbreviated: PVC) is the world’s third-most widely produced synthetic plastic polymer (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.
PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, food-covering sheets, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber. With cotton or linen, it is used in the production of canvas.

(Quoted from the Wikipedia)

Therefore, it is called “PVC” from the acronym of polyvinyl chloride.
Aside from figures, they are also used for plumbing pipes and power cords, and surprisingly, they are also used as materials for vinyl records, so we learned that they are used in a variety of products.

Why is it used for figures?

In summary.
・Softness can be changed at will.
・Easy to color and resistant to chemicals.
・Transparency is also possible.
It is a very convenient resin for figures that have complex shapes, require colorful coloring, and sometimes use transparent parts.

Does it get sticky if you keep it on display?

In the process of researching it, there were some articles that bothered me.
That is, over time, the surface will become sticky.

In order to adjust the hardness of the resin when manufacturing the figure, there is a “plasticizer” that appears on the surface of the figure over time, which is the cause of the stickiness.

What was surprising was that the plasticizer would accumulate in poorly ventilated areas and become sticky.
However, the secret to keeping your figures clean and clean is to put them out in a well ventilated place every once in a while and take care of them properly.
Of course, it seems better to store them in a cooler place, as high temperatures will cause the plasticizer to collect more on the surface. (It’s also written in the figure’s instruction manual that you should avoid places where it will be hot or in direct sunlight.)

That was the story of PVC!

In this article, we’ve looked at the raw materials used to make the figures, and if you know the properties of PVC, you’ll be able to appreciate your favorite figures for longer and in better condition.
After doing some research, I found out that it’s better to ventilate them moderately, so I’m going to take them outside every once in a while to love them.
