BAJAJ MASTERBATCHES FOR
FOAM EXTRUSION

It’s a process of melting plastic in an extruder, then adding a foaming chemical to create a cellular structure within the molten plastic. The foamed plastic is then formed by an extrusion or molding process. Commonly used foam extrusion process is XLPE & EPE Foams.
Expanded Polyethylene foam (EPE), is one of the most widely used plastic foams which is made by melting of expanded pellets (ie) EPE beads through heating, subjected to blowing agent and then explanded through cooling into a mold in a steam chest to make different shapes & objects as per the requirements. It is a lightweight, semi-rigid, flexible closed cell foam, most commonly used in packaging, for impact and shock absorption, vibration dampening and surface protection. It is also used in gym floor mats, Industrial floorings and to certain extent for insulation as well.
Cross-linked polyethylene foam (XLPE) is a closed-cell foam characterized by a compact feel and resistance to water. It is made in a batch type operation wherein PE is mixed with Organic peroxide & Blowing / foaming agent , then compressed and subjected to cross linking through heat and pressure at an elevated temperature . Finally it’s made as desired form / shape as per the requirements.As a closed-cell foam characterized by low moisture permeability and high buoyancy, it is widely used in different types of flotation equipment, food processing, gaskets, seals, toys, and expansion joints.
We at BAJAJ offer our specialized masterbatches for foam extrusion applications, they are :
ProductDescription
PLAST CLEAR FILLERTalc based transparent filler to facilitate smooth processing by means of creating cell structure , reducing cost by
replacing polymer content , power consumption and enhanced productivity.
PLAST ANTISTATIC ADDITIVEMasterbatch acts as a surface active agents, prevents moisture entrapment in cell structure, uniform size distribution
in cell structure and minimizes the build up of static electricity on finished foam sheets.
PLAST COLOUR MASTERBATCHESIn various shades as per the requirements to give aesthetic appeal, heat & weather resistant .
PLAST BLACKWith finest carbon particles gets uniformly distributed in foam structure to give good jetness, smooth surface finish and
UV resistance to certain extent when exposed in outdoor applications.
