A purging compound can do more than displace old material. See how PEKUTHERM functions as a mechanical cleaning, changeover and preventative maintenance tool for plastic processors.

Chemical and mechanical purging compounds may address similar production problems, but they clean in fundamentally different ways. Learn how chemical purging compares with Pekutherm’s thermoelastic mechanical soft-scrubbing action.

Fresh-resin flushing is one of the most common changeover methods in plastics processing. Learn how it works, its advantages, its limitations, and how it compares with thermoelastic mechanical soft-scrub purging.

Carrier-resin purges are one of the five primary categories of purging compounds used in plastics processing. Learn how they work, why manufacturers use them, and how their cleaning mechanism differs from Pekutherm® mechanical soft-scrub technology.

Not all purging compounds are designed to accomplish the same objective. Discover how lubricating purges differ from thermoelastic mechanical soft-scrub purging and why understanding the mechanism can improve changeovers, maintenance and part quality.

Not every purging method performs the same job. Learn how five common approaches use different mechanisms to address resin, color, carbon buildup and degraded polymer in plastic processing equipment.

Engineering resins such as Nylon, PET, and Polycarbonate create unique purging challenges. Learn how processors reduce contamination, downtime, and startup scrap.

UniTemp’s Pekutherm ULT was recently featured in PlasticsToday for its ultra-low temperature purging capabilities. The coverage highlights how Pekutherm ULT supports processors working with silicone, EPDM, and other low-temperature materials across injection molding and extrusion environments.

PEKUTHERM® ULT helps injection molders and extrusion processors reduce downtime, improve changeovers, and support low-temperature processing applications including silicone rubber and EPDM.

Carbon buildup inside plastic extruders can lead to black specks, contamination, downtime, and expensive screw pulls. Learn how preventative mechanical purging helps support cleaner extrusion operations and reduce buildup before it becomes a major production problem.

Black specks are one of the most common contamination issues in plastic processing. In injection molding and extrusion environments, degraded polymer, carbon buildup, trapped material, and improper changeover procedures can create recurring defects that increase scrap, downtime, and maintenance costs. This guide explains the root causes of black specks, how preventative purging reduces contamination risk, and why mechanical purging compounds are increasingly used to improve p

Learn how preventative mechanical purging helps reduce screw pulls, contamination buildup, downtime, and maintenance disruption in injection molding and extrusion operations.

Learn how to purge silicone and flexible materials without thermal degradation using low-temperature mechanical purging methods for cleaner, faster changeovers.

Polycarbonate processing temperatures increase contamination risk during resin transitions. Learn how mechanical purging compounds help prevent black specks and stabilize production quality.

PEKUTHERM® continues to set the industry standard for mechanical purging performance. Recent national media recognition highlights benchmark-level efficiency improvements in changeover speed, scrap reduction, and equipment cleanliness across injection molding and extrusion operations.

Black specks in plastic parts often come from carbon buildup or degraded polymer inside processing equipment. This guide explains the causes and how processors remove contamination.

Learn how to purge an injection molding machine step by step. This guide explains when to purge, why purging is necessary, and how purge compounds clean molding equipment.

Carbon buildup in plastic extruders can cause contamination and downtime. Learn what causes carbon deposits and how processors remove them from extrusion equipment.

Mechanical vs Chemical Purging Compounds: Mechanical purging compounds clean processing equipment through physical scrubbing action, while chemical purges rely on reactive additives that generate gas expansion.
