Additives are where polymer performance is actually decided, and where the technical knowledge is most concentrated in the fewest heads. It's also the part of plastics recruitment most poorly served: the pages that rank for it are near-duplicates of each other, written to catch a search term rather than to say anything.
Where we place
Stabilisers
Heat, light and UV stabilisers, antioxidants. Formulation and applications development, technical service, and the commercial roles selling into compounders and converters.
Modifiers
Impact modifiers, processing aids, plasticisers and flame retardants, including the reformulation work driven by regulatory pressure on established chemistries.
Masterbatch
Colour, additive and filler masterbatch. Colour matching and lab leadership, technical sales, product management, and plant and operations roles.
Compounding
Engineering compounds and specialty formulations. Process and extrusion expertise, quality, plant management and commercial leadership.
What makes additives hiring difficult
The knowledge is undocumented
Formulation know-how in additives frequently lives in the heads of a handful of long-serving people, and in lab notebooks rather than systems. When one of them leaves, the capability leaves. It's the clearest example in plastics of why a technical hire is a continuity question, not a headcount question.
Regulation is rewriting the portfolio
Restrictions on established flame retardants, plasticisers and stabiliser chemistries mean the valuable candidate is the one who has substituted a working system and kept the performance. Reformulation experience is now worth more than years served.
Recycled content changed the technical problem
Additive packages designed for virgin polymer behave differently in recyclate: contamination, inconsistent feedstock and degraded material all interfere. Formulators who have solved for post-consumer content are in demand from every direction and there aren't many of them.
It's a small world
Additives professionals mostly know each other. Confidential searches leak easily, and a badly handled approach is remembered. This is a sector where being already trusted in the market matters more than the size of anyone's database.
How we work
Retained for technical leadership, plant management and any search where losing the knowledge would hurt. Contingent for technical service, applications and commercial roles with an active market. RPO when a compounding site is scaling.
Questions we get asked
Do you recruit for masterbatch as well as additives manufacturers?
Both, along with compounders. Working all three ends keeps the market map accurate, because people move between them constantly.
Why are formulators with recycled-content experience so hard to find?
Additive packages developed for virgin polymer behave differently in recyclate, and relatively few formulators have worked through the contamination and consistency problems that creates. Demand for that experience has risen faster than the number of people who hold it.
How do you protect confidentiality in a small sector?
Retained, unadvertised searches with the client unnamed until a candidate is qualified. In a market where most senior people know each other, discretion is a practical requirement rather than a courtesy.
