RPU® spray technology

Innovative spraying technology of polyurethane mixtures,
with low pressure dosing system and self-cleaning head.

An automated process that establishes the highest standards
in moulding definition
, enhancing the characteristics
of the polyurethane where the highest quality production level is required.

A process that guarantees

  • Precision and uniformity in polyurethane distribution
  • High productivity
  • Wide range of flow rate, for different applications

Intermittent operations with short or long intervals between
a process and the subsequent.

RPU® spray soles

Maximizes the properties of polyurethanes

RPU process, allows to maximize the anti-slip characteristic of the sole, with high definition of details even over sharp “edges” or complex patterns.

It allows manufacturing articles free of defects caused by air bubbles, with extremely thin or high thickness.

Complete support to the customer

Thanks to the deep know-how and experience gained over the years on RPU technology, STEMMMA guarantees a complete support to the customer concerning mould design, the supply of dedicated softwares, tools to optimize the spraying process and advice over the choice of the materials that fit best each application.
