Grade strengths
The maker positions RX at carbon-residue jobs, with Glass Fiber scouring the barrel
Use cases
Jobs where carbon has built beyond normal purging, on machines without Hot Runner; the RE TDS states RE chase-purges after RX
ASACLEAN R-Series · carbon deposits
RXASACLEAN purging compound for carbon residue
High cleaning power for carbon residue, using Glass Fiber
RX is an R-Series grade alongside RU and RE The maker states RX carries Glass Fiber for carbon-residue jobs, barrel-section use only, and no machine sealing. Values below come from manufacturer documents, not yet confirmed by a verifiable Thai TDS.

Definition & positioning
What jobs fits RX
RX is positioned for jobs with accumulated carbon residue, using Glass Fiber to scour the barrel — unlike RU for color and material change and RE for low residue
Source: Every value in this table comes from Asahi Kasei manufacturer documents, not yet confirmed by a verifiable Thai TDS — so RX stays out of the grade recommender
- Process
- Injection and extrusion, barrel section only, no Hot Runner
- Resin
- Jobs with accumulated carbon residue; supported resin types await the Thai TDS
- Temperature
- 180–330°C per manufacturer data
- Objectives
- Carbon-residue cleaning; the RE TDS states RE chase-purges after RX
- Hot Runner
- Not used; maker restricts to barrel section
- Glass Fiber / Additives
- Contains Glass Fiber
- Machine Sealing
- Sealing prohibited
- Residence / Clearance
- No barrel residence at any temperature; clearance and screen mesh await the Thai TDS
