Ramclean

Producer: POLYRAM
Polymer type Purging Agent
Smart purging agents RamClean® help to reduce downtime and minimise scrap rate thanks to better purging. 

RamClean® has a working temperature range from 150°C to 360°C (dependent on grade), making it suitable for the cleaning of most polymers. RamClean® is supplied as a masterbatch and therefore it is easy and safe to use and handle.

General info

Smart purging agents RamClean® are solution for:

  • Colour changes 
  • Material changes 
  • Black specking 
  • Colour/Material streaking
  • Shut-down procedures

Triple purging effect of selected RamClean® grades:

  • Physical: non-abrasive scrubbing and removal of degraded deposits
  • Chemical: reacting with deposits to break down polymer chains and ease purging 
  • Heat activated foaming agent – to clean hard-to-reach places and negative flow areas 

Key properties of smart purging agents RamClean®

  • Fast and effective
  • Easy to use
  • Safe to use and handle
  • Non-corrosive
  • Non-toxic
  • Non-abrasive
  • REACH and FDA compliant

Processing

Recommended quantity of smart purging agent RamClean®204 and 800 Impact resistance for different high heat polymers

Recommended usage of RamClean® 800

RamClean® 800 - designed to clean materials with working temperatures 230°C –360°C: PP, PE, PA, PC, PS, EVOH, ULTEM, PEX, PPO, PPS, Polysulfane and more.

For cleaning cylinder, screw, die and mould:

  • Stop feeding the extruder with the material in use.
  • Clean the Hopper and surrounding area very carefully.
  • Clean the colour dispenser (if applicable). If possible, shut it down and remove it.
  • Empty the extruder.
  • Raise working temperatures by 10°C. For heat sensitive materials, do not raise temperatures more than those recommended by the resin manufacture.
  • Raise the Back pressure to the highest safe level.
  • Start filling RamClean® 800 until its flows out from the mould, using 30-40% the regular RPM.
  • Stop the screw and let RamClean® 800 sit for 2-3 minutes.
  • Dismantle and clean the "die" if necessary (if purge is dirty, rough and contaminated).
  • Start purging out RamClean® 800: 
  • a) By injecting it through the opened mould at a low injection pressure. Or
  • b) By closing the mould and injecting products at half the weight. 
  • If contaminants are still visible after most of RamClean® 800 is flushed out, add more and repeat steps 4 to 9.
  • Add the next material to use and continue injecting half weight parts until all RamClean® 800 is out.
  • Resume production using normal production settings.

Recommended usage of RamClean® 204

RamClean® 204 - designed to clean materials with working temperatures 150°C –260°C: PP, PE, PA, PBT, PC/PBT, PC/ABS, ASA/PBT, PC/ASA, EVOH.

For cleaning cylinder, screw, die and mould:

  • Stop feeding the extruder with the material in use.
  • Clean the Hopper and around it very carefully.
  • Clean the colour dispenser (if exists). If possible, shut it down and remove it.
  • Empty the extruder.
  • Raise working temperatures by 10°C. For heat sensitive materials, do not raise temperatures more than those recommended by the resin manufacture.
  • Raise the Back pressure to the highest safe level.
  • Start filling RamClean® until its flows out from the mould, using 30-40% the regular RPM.
  • Stop the screw and let RamClean® sit for 5-15 minutes. Fot heat sensitive materials, don't stop for more than 5 minutes.
  • Dismantle and clean the "die" if necessary (if purge is dirty, rough and contaminated).
  • Start purging out RamClean®
  • a) By injecting it through the opened mould at a low injection pressure. Or
  • b) By closing the mould and injecting products at half the weight. 
  • If contaminants are still visible after most of RamClean® is flushed out, add more and repeat steps 4 to 9.
  • Add the next material to use and continue injecting half weight parts until all RamClean® is out.
  • Resume production using normal production settings.
