Processing Aid

It is a fluoropolymer-based additive that are designed to improve the melt processability and handling of high molecular weight polymers. They can also give finished articles improved aesthetic properties by removing flow marks and die lines thereby improving the parts gloss and clarity.

Key benefits

  • Eliminate melt fracture and ‘shark skin’ of film.
  • Reduce die-build up and increase output of machine.
  • Reduce gel formation and die lines.
  • Improve gloss, surface smoothness & transparency.
  • Lower Energy consumption
  • Reduction of cycle time and quicker transitions
  • Faster color changeover


  • Blown & cast film production
  • Pipe & sheet extrusion
  • Cable & Pipe extrusion
  • Fiber & monofilament extrusion
  • PP artificial grass & carpet backing
  • Blow & injection molding process
  • LLDPE / m-PE Blown Films
  • HDPE Blow Molding
  • PP Sheets / Foam / Corrugated Boards

Lubricant Additives

PTMB is leading supplier of molybdenum disulfide (MoS2) masterbatches for internal lubrication of nylon films and injection molded parts. It reduces or eliminates mold drag during molding and acts as a mold release. Post molding component assembly is made easier because of the self-lubricating properties.


  • Injection Molding
  • Film, Sheet & Profile Extrusion
  • It is a Black in Color.
  • Recommended LDR: 4-5% (For PA & PET)

Mold Release

Mold release additives are designed to improve your injection molding process by reducing friction, allowing more efficient processing and improving part quality time after time.

Key benefits

  • Reduce Coefficient of Friction of Film & Sheets.
  • Increase Mold and Torque Releasing Properties.
  • Improve Gloss and Surface Finish of Plastics product.
  • Scratch and Scuff Resistance.
  • Reduce Cycle Time and Rejection.
  • Reduce Wear of Screw and Barrel.

Moisture Absorber

Moisture absorber or scavengers sometimes refer as desiccants or life extenders masterbatch which attract or chemically bind moisture. It is an economical way to remove moisture from plastics during processing.

PTMB offers high quality moisture absorber masterbatches to use in recycling and virgin polymers.


  • Reprocessed PP resin
  • Reprocessed PE resin
  • Slightly wet virgin PP / PE resins
  • PP / PE with embedded moisture

Silicone Masterbatch

Silicone Masterbatch is formulated using high molecular weight poly-dimethyl-siloxane (PDMS) additives which is well dispersed in Polyethylene. It gives superior and permanent lubricated surfaces to plastics product.

PTMB provide high quality silicone masterbatches which are widely used in various polymer for compatible systems to impart benefits like processing improvements and surface modification.

Key benefits

  • Reprocessed PP resin
  • Reprocessed PE resin
  • Slightly wet virgin PP / PE resins
  • PP / PE with embedded moisture


  • Fiber optic cable duct pipes.
  • PLB duct pipes.
  • Internal mold release agent.
  • Injection molding products.
  • Bottle, Drums, Jerry cans.
  • HDPE boxes and bottles.
  • Packaging films.

Chain Extender

PET is a polymer highly susceptible to the hydrolytic reactions that occur during processing. These reactions lead to the decrease of molecular weight of the polymer, limiting the recycling number of the material.

Chain Extender reacts chemically, during the extrusion process, with the hydroxyl groups of the oligomers, increasing both molecular weight and viscosity of the polymer.

Key benefits

  • Increased the IV of recycle PET.
  • Increase molecular weight
  • Increase melt viscosity
  • Increase melt strength

MFI Enhancer

Melt flow enhancer is organic peroxide-based additive which help to improve the flow property and narrow molecular weight distribution of Polymer. It degrade the polypropylene backbone via beta-scission to adjust the melt flow and narrow molecular weight distribution.

PTMB having high and low concentrated masterbatch for Polypropylene Polymer application.

Key benefits

  • Increase melt flow
  • Improve mold filling
  • Reduce cycle time and short weight
  • Increase loading of filler


  • Recycling polymer
  • Fibers & filament
  • Pipe & sheet
  • Injection items

Purging Compound

A purging compound is designed to clean all primary plastic machinery when changing color, resin or simply to remove black specks or contaminations.

PTMB Purging compound is designed for better and efficient clean-up of extrusion, injection and blow molding machines. It is a low-cost cleaning compound that saves money through lower wastage and quick change over and reduced downtime.

Key benefits

  • Faster color change
  • Reduce downtime of machine by 50%
  • Reduce cross contamination
  • Reduce degraded polymers, pigments and additives from extruders and die.
  • Remove and reduce black specs & contaminations
