Dynamic mixing for flexible, integral-skin, rigid and semi-rigid foams.
Overview
The ST-C is a low-pressure metering machine with a dynamic mixer, developed for polyether or polyester polyurethane. It is suited to flexible foam, integral skin, rigid and semi-rigid foam.
Dynamic mixing offers flexibility for lower outputs, systems with more than two components and high-viscosity materials. It serves sectors such as automotive, refrigeration, furniture, construction, orthopaedics and sports.
A mixing rotor in the chamber homogenises the components at low pressure.
Configurable for both polyol families.
Flexible, integral skin, rigid and semi-rigid.
Head on a boom to reach moulds and workstations.
Applications
Listing an application does not guarantee compatibility with every material in that sector. Each case is assessed.

Next step
To recommend a configuration we need to know the product, the polyurethane system, the mix ratio (by weight or by volume), the target output and the operating mode.
Send requirementsInformation source. Description based on Sulpol’s previous public communication. Current models and configurations on request.
Metering and mixing
Portable metering
Portable metering with Sulpol engineering: up to 15 or 30 kg/min, 1:1 mix ratio by volume.
High pressure
Impingement mixing at high pressure with a self-cleaning head and no solvent flushing.
Elastomers
Low pressure for PU elastomers: up to 150 kg/min, up to 150 °C, dynamic head and up to 4 additional components.
Application engineering
We will look at your application, target output and metering requirements to assess the right equipment configuration.
