ecomaru (Purging compound using grass wool)

"ecomaru", a series of purging compound made of resin filled with glass wool (GW), was first introduced in Japan in 2018 from the maker Nanodax (Tokyo, Japan).  Yasukawa is the first distributor appointed by Nanodax.  

 

Ecomaru cleans strongly and thoroughly contamination (black specks (carbides) and color) inside mold injection machines, with less waste and less odor.  In many use cases, because of its unprecedented performance,  ecomaru is even replacing disassemble-machine-to-clean process (conditions may apply).   In such cases, the time to complete the cleaning work had decreased from two to three days to merely an hour.

 

We are proud of ecomaru being an upcycled product from glass wool and contributing to SDGs created by the United Nations. 

 

ecomaru samples are available to overseas markets.

Grass wool mechanism in purging

100 % owned patents realizing distinctive performance of ecomaru.

 

Originally the technologies for producing resins filled glass wool were codeveloped by Nanodax and MAG-ISOVER K.K. a subsidiary of Saint-Gobain SA in France (glass and chemical material manufacturer), and now all the technologies and patents are 100% owned by Nanodax after all were transferred from Sain-Gobain Group.  Currently, Nanodax owns 9 patents in Japan, 17 patents in 11 overseas countries, and 6 PCT pending.

 

Grades of ecomaru

 

We have a wide range of ecomaru to meet customer requirements.

 

Please inform us of your needs (resins and machines used), and we can give advice on the grades and purging process.  


Use case  (One of examples for better understanding of what ecomaru can do)

 

Conditions given: 

Automotive component production, changing from ABS (black) to PC-ABS (natural) = resin and color change

 

Cleaning process:

Step1   Cleaned with used's conventional surfactant type purging compound.  The color soon changed to white by which the purging was finished.

Step 2  Cleaned the machine with ecomaru, just after completing Step 1.  Initially parts with gray color (not natural color) and black specks were generated, though it was just after completion of Step1 (cleaned with a conventional surfactant purging compound). 

 

Result and observation:

The Step 2 was finished when further gray color and black specks were no longer observed.  The contamination reached and take away by ecomaru was those that could not be cleaned by the former Step1 process.  This shows strong cleaning ability ecomaru has.
