Know-How

Compounding, the way only those who know it can do it.

  • PP · PE · PS · EPDM
  • Conto terzi
  • ISO 9001
  • Dal 1991

Over 35 years of continuous collaboration with the leading European chemical and petrochemical groups have built a rare asset: full command of formulation, process and quality control across PP, PE, PS and EPDM. Not a service — an industrial extension of the client.

Our strengths

Excellence in contract compounding.

We combine specialist know-how, partnerships with the main industrial groups, certified quality and production flexibility.

  • Proprietary know-how

    Over 35 years of experience in polymer compounding, built in continuous collaboration with the leading European chemical and petrochemical producers. A body of technical expertise — from formulation to process fine-tuning — that cannot be acquired, only built over time.

    35+

    Years of know-how

  • Alongside the major groups

    We operate as a manufacturing partner for major international chemical companies. This relationship of trust, built over decades, demands — and has taught us — the highest quality and operational standards in the industry.

    100%

    Contract only

  • ISO 9001 certified quality

    Our Quality Management System is ISO 9001 certified. Every stage of the production process is tracked, documented and repeatable: from raw material intake to conforming batch release.

    ISO

    9001:2015

  • Contract manufacturing flexibility

    From initial sampling to industrial-scale production, output capacity and lead times adapt to the client’s requirements. Whether full tolling or raw-material procurement, the contractual model is defined case by case.
