Tiny burrs on a hypodermic needle.It would be ideal if the needle can be smoothened on the inside as well. The question is.., “How ”

NEPLOS process is the answer

Chemistry is our friend!…What does the word "chemistry" make you think of ?

Something incomprehensive? Something difficult? Something dangerous? A cause of

pollution? Or...?

"Why does water put out fire?" - How well can you answer a simple question like this?

"Chemistry" is all around us. Removing oil spots and dust. Finishing up paint jobs.

Wearing makeup, cooking, laundering, taking medicines...

That's right. Just everyday things. But they are all related to "chemistry," and are all

very important. Not to mention, very complicated, too.

Yokohama NEPLOS is a company that deals with and pursue such things.

"Chemistry is our friend." This is our motto.

CEO Shinichiro Hayashi
