Purging Compound Market to Rear Excessive Growth During 2025
Purging
compounds are gaining increased significance for maintaining the
operational efficiency of modern thermoplastic processors. These
cleaning compounds, containing a base resin along with other
additives, have a variety of applications in polymer processing and
are found to be suitable for a variety of screw and barrel
assemblies, extruder die sets, and tooling. The application of
purging compounds has been found to be useful in removing the carbon
buildup in assemblies, reducing machine down-time, and improving the
processing efficiency. In addition, their uses have been found to be
instrumental in decreasing scrap rates caused by color and polymer
changes. These all factors play a crucial role in enhancing process
efficiencies and optimizing the entire manufacturing processes
associated with thermoplastics.

Compared
to traditional processes consisting of the use of regrind or virgin
resin, purging compounds facilitate the removal of carbon and color
deposits in the final products. This leads to fewer rejects and
eliminates material waste to a large extent. In addition, the use
compounds also prevents screw-pulls. Furthermore, this helps to keep
injection molding machines in good condition, thereby decreasing
machine overhaul time. The choice of an effective purging compound
depends on the specific type of raw materials to be purged off.
Polyolefins, high temperature resins, and engineered resins are some
of the key polymers that need to be purged off. The demand for
improving production efficiencies and reducing cost is a key factor
boosting the adoption of purging compounds in the plastics industry.
Purging
compounds are chemical cleaning compounds that contain certain resins
and additives in their formulation. They are widely used with various
polyolefins such as thermoplastic olefin (TPO), polypropylene (PP),
and polyethylene (PE); high temperature resins such as polysulfones
(PSU) and polyether ether ketone (PEEK); and engineered resins such
as high impact poly styrene (HIPS) and polyamide (PA). Purging
compounds are extensively employed to clean extruder lines and molder
machines. Furthermore, these compounds are used to clean palletizing
units in various chemical operations. They are also employed to clean
carbon deposit and to bring about color and material changes. Purging
compounds help clear machines in quicker time. They are also more
efficient compared to traditional cleaning methods such as purging
with regrind. Benefits of using purging compounds include less scrap,
reduced downtime, low production cost, and less material waste.
The
global purging compound market can be segregated in terms of product
and process. In terms of product, the market can be categorized into
mechanical purging, chemical purging or foaming purging, and liquid
purging. Mechanical purging compounds generally contain
high-viscosity polymers and are used to eliminate scrap materials
from screws, dies, and barrels. They do not require any residence
time and neither aid in chemical reactions. Chemical purging
compounds contain ammonia and other foaming agents that need
residence time of 15 minutes to 30 minutes. These compounds
facilitate chemical reactions and eliminate residue by reducing
viscosity and molecular weight of the scrap material. They are used
typically in low pressure areas.
Chemical
purging is the leading product segment of the purging compounds
market, followed by mechanical and liquid purging. Growth of the
chemical purging segment can be ascribed to its features such as high
moldability rate. Based on process, the market can be split into
extrusion, blow molding, and injection molding. Demand for purging
compounds in the injection molding process is expected to rise
significantly during the forecast period. Injection molding process
is one of most popular processes for producing plastic parts. It
involves many machine tools and configurations that need continuous
scrap removal and carbon cleaning. Adoption of injection molding in
the extrusion process is anticipated to increase, as it offers
certain benefits such as fast contaminant removal.
Rapid
growth in the chemical industry coupled with increasing demand for
cost effective scrap removal solutions from equipment to control
corrosion and carbon deposition are driving the purging compound
market. Furthermore, increase in mergers and acquisitions to enhance
product offerings is another factor positively influencing the
market. For instance, Chem-Trend L.P, a leading manufacturer of
purging compounds, acquired Moulds Plus International’s business
‘Ultra Purge’ in 2016 to broaden its thermoplastic processing
portfolio. Volatility in raw material prices due to variations in
crude oil prices may hamper market growth. There exists intense
competition in the purging compound market. Manufacturers are
focusing towards improvement and development of innovative product as
per consumer requirement. All these factors are responsible for
market’s growth
In
terms of region, the purging compound market can be segmented into
North America, Europe, Asia Pacific, Latin America, and Middle East &
Africa. In terms of consumption, North America is the leading region,
followed by Europe and Asia Pacific. High number of plastic
processing plants coupled with rising demand for purging compounds,
typically in engineering thermoplastics, is propelling the purging
compound market in North America. The purging compound market in Asia
Pacific is expected to expand significantly due to the rapid
industrialization, which can lead to expansion of various industries
such as petrochemicals, chemicals, and automotive. Latin America and
Middle East & Africa are the lucrative regions of the purging
compounds market due to the revival in their economy and rising
investment by various manufacturers. Increase in research &
development and brand promotion are likely to create new avenues for
manufacturers of purging compounds.
