Special Compounds · STIR Compounds

Tailor-made formulations
for every need.

When standard compounds are not enough, STIR designs solutions to specification. Masterbatches, thermoplastic elastomers, flame retardants and functional blends for sectors where performance is non-negotiable.

Product philosophy

Tailored chemistry
is our
answer to the challenges
of your processes.

Every special compound comes from in-depth technical dialogue with the customer. We start from the analysis of the production process, applicable standards and expected performance to define an optimal formulation.

Our in-house laboratory develops and tests every blend on pilot plants before starting full-scale production. Batch traceability is guaranteed from the arrival of raw materials to the delivery of the finished product.

Research & Development

The formulation development process

Our development methodology reduces time-to-market without compromising quality. Every project goes through structured and documented phases.

Shared technical brief Collection of specifications: application, standards, processing, expected volumes. Internal feasibility analysis.
Formulation design Selection of raw materials and additives. Calculation of process windows and simulation of expected properties.
Prototyping & testing Production of samples on pilot scale. Laboratory characterisation: rheological, mechanical, electrical, thermal and smoke.
Validation & scale-up Customer approval, production scale-up, pre-delivery quality control and management of certificate of conformity.
