Additives play a role in polymers just like common salt plays in food — a small quantity can completely change the final outcome.



Polymers alone rarely meet the full performance requirements of end-use applications.

While base resins provide the backbone, they often lack the necessary stability, processability, and functional properties needed in real-world conditions.


That’s where additives come into play — enabling processors to tailor materials for performance, durability, and efficiency.

As processing engineers, we know that the right additive package is not just an option it’s a necessity.

Key Additives Used in Polymer Processing & Their Functions


Processability Improvement-


Processing Aids (PPA) –


Internal (e.g., fatty acid esters)

External (e.g., waxes like PE wax)


Reduce melt fracture, improve flow

Lubricants (internal & external) – Smooth processing


COF Control (Slip Performance)

Slip Agents –

Erucamide, Oleamide.


Anti-Blocking (Film Handling)


Silica, Talc – Prevent film sticking

PMMA-based antiblocks


Thermal Stability (During Processing)


Primary Antioxidants (Hindered phenols)

Secondary Antioxidants (Phosphites)


Anti-Fogging (Packaging Films)

Glycerol esters

Sorbitan esters


UV Protection (Outdoor Stability)

UV Absorbers


HALS (Hindered Amine Light Stabilizers) Antistatic (Charge Reduction)

Ethoxylated amines

GMS (Glycerol Monostearate)


Anti-Corrosion (VCI Films)

Amine-based corrosion inhibitors


Key Insight-


Polymers give structure — additives give performance.”


The success of any polymer product lies not just in resin selection, but in designing the right additive combination to meet processing and end-use demands.


Quick View

POLYMER + ADDITIVES = PERFORMANCE


Processability → PPA, Lubricants

Surface Control → Slip, Antiblock

Stability → Antioxidants, UV Stabilizers

Functionality → Anti-fog, Antistatic

Protection → VCI (Anti-corrosion)


Result: Better Processing | Longer Life | Enhanced Performance

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share : A BUG IN INJECTION MOLDING

Image
Today's KNOWLEDGE Share A bug in injection molding – an injection-molded part in a bug? Neither! Nature and injection molding have reached similar results. Nature created the first micro-gear long before any human engineering existed. One such example is the Issus coleoptratus (shown in the picture). Furthermore, only now are we reaching the point where injection-molded polymer microgears can approach this level of performance. Looking at the images, which one do you think is the natural gear, and which one is the molded version? It is not that easy to tell, right? Their appearance and operating principles are surprisingly similar. Chitin, a natural linear polymer, forms what nature essentially "molds” into shape. In engineering, we rely on advanced technical polymers to produce similar geometry through actual injection molding. They are not the same material, yet they solve the same issue: Stiffness, dimensional stability, and reliable function at a scale where tolerances...
