© 2025 TBM Co., Ltd. All Rights Reserved. Eco-conscious Purging Material for Resin Molding Machines : LIMEX Purge Product Introduction It is a material used to clean the inside of resin molding machines (injection molding machines, extruders etc). It removes residual old resin, colorants, and carbon deposits, assisting in material changeovers and defect prevention. Among many purging materials, “LIMEX Purge” contains more than 50 % inorganic components such as calcium carbonate (limestone), enabling reductions in plastic consumption and greenhouse-gas emissions (including CO2) compared with conventional plastics, while also achieving cost savings. What is a purging material? It covers everything from general-purpose resins to engineering plastics, offering grades suitable not only for injection-molding cylinders/screws but also for blown-film molding, blow molding, and extrusion molding. *Supplied in pellet form, it can be used as is. Compatible with a wide range of resins 2

Features In addition to its environmental performance that contributes to reducing plastics and CO2, it also achieves high production efficiency through excellent cleaning effectiveness. Sample Available Product Introduction LIMEX Purge G, compared to petroleum- based plastic, not only cleans in a short time and with a small amount, but also enables a reduction in resin changeover time for subsequent production. By incorporating over 50% inorganic materials such as calcium carbonate (limestone), it can not only reduce plastic usage and greenhouse gas (including CO2) emissions compared to conventional plastics, but also to achieve cost reduction. It is a high-quality product that has passed rigorous tests, as evidenced by its track record with Tier 1 suppliers. Its reliability and performance have been recognized, leading to its adoption by many companies.

Product Introduction How to use LIMEX Purge (injection molding) Basic usage 01 02 To clean the cylinder/screw of an injection molding machine, set the molding conditions as shown in the table below and repeat metering and injection, after finishing the molding of preceding resin. After purging, switch to the molding conditions for the next resin. Once the temperature stabilizes, discharge LIMEX Purge G with the next resin. Metering volume Cylinder temperature Rotational speed Back pressure Injection speed 10-30mm Same as during molding of the previous resin 30-70% About 5% 50-80% Usage flow ※Molding Conditions Short purge : a purging method that repeats high-speed injections with a small metering volume. Metering volume : about 10 % of the maximum Injection speed : 50–100 mm/sec or higher Usage guideline（※LIMEX Purge G） Machine size (clamping force) Approximate usage amount (kg) 80ton 0.3～0.4 kg 125ton 0.4～0.6 kg 550ton 2.0～3.0 kg 800ton 4.0～6.0 kg 1250ton 6.0～8.0 kg 1800ton 10 ～12 kg *If residue is a concern, perform a short purge with the nozzle pulled back. White streak-like residues of the purging material may remain. If residue is problematic, stop molding, reduce the metering volume as much as possible, pull the nozzle away from the mold, and perform repeated metering and injection for purging. *The calcium carbonate in LIMEX Purge is an inorganic material that causes far less metal wear than glass fillers (GF). Even short purges will not damage the screw. Cleaning Discharge the Preceding resin as much as possible. Preceding resin discharge Perform a light purge at low back pressure based on the usage guideline. Replacement with subsequent resin Purge with subsequent Resin. Thoroughly replace by using short purges Start molding 7
