Misumi Purge Agent (20 kg/bag)
Part Number: MPG-HR

Specification Table

Generally, PVC has a molding temperature of 170°C or less, but the purge temperature should be increased to around 170°C for use.
Although POM is an engineering plastic, it has a low molding temperature as a rule, so the use of MPG-S is generally recommended.
The packaging is 20 kg per bag. Be sure to order in units of bags. For example, when ordering 200 kg, set the quantity to 10.

                                        ◎: Recommended ○: Usable △: Unsuitable
 "Retention" refers to the molding machine not discharging the purge agent from the overheating cylinder during operation, and instead keeping it at the molding temperature for several minutes (3 to 5 minutes) in the heating cylinder.
 "Long-term filling" refers to filling the inside of the heating cylinder with a replacement purge agent and keeping it with the heater power off or at low temperature for 24 hours or longer.
MPG-G cannot be used for retention, long-term filling or cleaning hot runners.
 

■More Effective Usage
• The purge temperature is the same as the molding temperature of the molded resin, but it is more effective if set higher by 5 to 10°C in the front part of the heating cylinder and the nozzle.
• For stubborn dirt on the nozzle and screw head, it is recommended to retain the purge agent for several minutes (3 to 5 minutes)
and then perform a short purge. This usage method is prohibited for "MISUMI Purge MPG-G".
• If the previous resin remains in the vicinity of the nozzle and check valve, it is recommended to fill the purge material while allowing the nozzle to come in contact with the mold (covering the nozzle hole) to apply back pressure,
then retract the injection table and perform injection two or three times to purge.
• After washing with "Misumi Purge", it may remain if the resin to be molded next is highly fluid.
In this case, it is recommended to perform auxiliary purging using the same type of resin with low fluidity before molding.

■Precautions for Use and Handling
• Be sure to read the SDS (MSDS) before use.
