~It has a long history~

this site product page "Squeegee Rubber."
Squeegee Rubber named "urethane squeegee" is on it.
Nowadays, when it comes to squeegees, urethane rubber is the mainstream.
The word "urethane" has disappeared from the name of the latest squeegees.
 
Now, high-performance new products such as "e-fine squeegee" are on sale,
The "urethane squeegee" is no longer considered good in terms of performance.
We still receive many orders every month.
So why is this squeegee labeled with the word "urethane"?
This is because the squeegee has a long history of screen printing.
 
One day, when I was organizing materials related to squeegees, I suddenly became interested in the word "urethane".
I checked the development history of this squeegee.
I read an old technical book and found that natural rubber and synthetic rubber were used for squeegees around the 1955s.
Therefore, it is weak against solvents and has a short life.
The urethane rubber used in today's squeegees was developed in the 1965s.
It must have been difficult to manage the squeegee at that time.
 
By the way, looking at the records kept at our company, we can see that the accessories for the screen printers we shipped in the 1965s
There was a description of "urethane squeegee".
By that time, the "urethane squeegee" had already existed.
It seems that urethane rubber was applied to squeegees shortly after it was developed.
Since urethane rubber was a new material at the time, the name "urethane" must have been added to the product name.
 
Unfortunately, we did not have any record of the development time of the "urethane squeegee".
Or rather, it may be correct to say that I couldn't find it.
After all, there is no one left in the company who knows what happened at that time,
Even if I asked various people, all the answers were "It was already there when I joined the company."
 
Therefore, we asked the manufacturing consignment manufacturer to check the past manufacturing history.
As a result, this squeegee purchased urethane material from overseas in 1967,
After conducting rubber compounding and evaluation, I learned that it has been on the market since around 1968.
46 years since we started selling! !It is a super long-run product! !
 
We have been selling screen printers since 1964.
Four years later, the "urethane squeegee" was released.
Since the screen printer has since been replaced by a new model,
This squeegee is the oldest product that we currently sell.
 
By the way, the "urethane squeegee" has been improved for the first time in 46 years.
This squeegee has a slight odor due to the compounding agent, and it has been pointed out that it stinks inside the storage room.
Therefore, we reviewed the formulation and made it odorless.Of course, physical properties do not change.
The history of the refreshing "urethane squeegee" has begun.
