PPA Masterbatch

Introduction

Polyfill’s Natural Polymer Processing Aid Masterbatch - PT3001 is a new generation, highly technical product, suitable for controlling and eliminating the problem of Melt Fracture or Shark Skin Effect, during the process of LLDPE / LDPE / HM – HDPE by extrusion process.

Melt Fracture is generally the surface imperfection seen as a regular ridged surface with ridges running perpendicular to the extrusion direction especially in films, which is also known as “Shark Skin Effect”.

Advantage

  • PT3001 can offer performance and cost advantage. It exhibits exceptional commercial utility in low melt index film grade LLDPE , HDPE, HMHDPE. It is especially effective in Polyolefin Resins containing talc and silica based Anti blocking agents, TiO2 based pigment and other inorganic additives. It can also be used at low levels to reduce extruder Die built up when processing LLDPE, Eva and other Polyolefin resins.
  • PT3001 is designed for use at a very low level to improve processing of thermoplastics. It does not alter or detract from the good physical properties associated with high strength plastic.
  • PT3001 lowers apparent melt viscosity and permits processors to use high strength resins which otherwise could not be processed on available equipment. Now, with the aid of PT3001 fabricators can produce films of improved strength and quality. As Polymer processing additive, this Masterbatch can reduce or eliminate Melt Fracture and can reduce extruder torque.
  • Through optimisation of the extrusion process, the use of PT3001 can also lead to an increase in output and yield films with enhanced and bi-directional physical properties and improved clarity and gloss.

Features

  • Broadens extrusion processing capabilities of polyolefin resins.
  • Reduces or eliminates Die built up.
  • Lowers apparent Melt Viscosity.
  • Ideal for use in low MFI LLDPE, HDPE & high molecular weight HDPE resins.
  • For use at low levels.
  • Can offer performance & cost advantages.
  • Imparts a smooth, glossy and even surface to the extrudated / film.
  • Allows the process film with narrow die gap which results in balance of bi-directional properties and hence, more uniformity in film thickness and coating guage.
  • Reduces the wear and tear of the melt line, as a result increases the life of the processing equipment.
  • Reduces the chance of degradation of polymer and colours as it lowers the resistance time of melt through faster plastication.
  • Lowers the processing temperature, hence reduces electrical energy consumption by 5-15%.
  • Reduces the melt COF and hence there is an increase in output rate by about 10-15%.

Dosage

PT3001 Masterbatch is to be mixed with polymers in a dosage of 0.5 – 2% for LLDPE AND HDPE. Generally the 0.5% use of this Masterbatch gives a good result for processing film.

Caution

Over heating can cause chemical decomposition of the resin and the individual ingredients in the formulation. This could result in cross linking, molecular scissions, discolouration, odours or the evolution of toxic by products.
