Solutions of specified formulations can be produced from "50L" onwards. Free sample testing ISO 9001 certified factory

Our company specializes in the dissolution processing of rubber and resin (plastic) using organic solvents (hazardous materials class 4) and offers OEM services. ■ Feature 1: Small batch and spot production are acceptable Dissolution processing can be done from a minimum of 50L to a maximum of 3,000L, allowing us to produce only the necessary amount of dissolution liquid with specified formulations. *High-viscosity solutions can also be stirred (up to 60,000 mPa·s). We respond to needs such as: "I have a small demand but want to continue producing," "I want to produce a small amount on a spot basis as we are in the development stage," "I want to create a production record just once for BCP considerations." ■ Feature 2: Efforts to prevent contamination Generally, it is said that cleaning the interior of stirring tanks for hazardous materials is difficult, but our tanks can be disassembled after each product change to remove residues adhering to the inner walls and blades (for tanks below 200L). *For more details, please download the PDF or feel free to contact us.

Detailed information

To prevent accidents with hazardous materials, all of our mixing equipment is designed with "explosion-proof structure" and is "20-gallon tanks."
Even for small-scale or spot production, hazardous materials incur costs such as inventory and disposal expenses if produced in excess. Our stirring tanks can be selected in sizes ranging from a minimum of 50L to a maximum of 3,000L, allowing you to manufacture only the necessary amount tailored to demand.
Our specially designed mixing kettle can be disassembled for each product change to remove any residual material adhering to the inner walls and blades (for kettles under 200L).
