Thermoplastic Extrusion - Product Specification
A reflectorised thermoplastic road marking material available in various levels
of Luminance, Skid Resistance & Reflectivity, and in various colours.
Extrusion materials are thermoplastics, which possess higher viscosities than
spray plastic materials.
The application to the road surface is achieved by either an auger or a
Extrusion thermoplastic product consists of a mixture of light coloured
aggregates, pigment and extender bound together with a thermoplastic binder
The exact composition of an Extrusion thermoplastic grade will depend on the
specification requirements, and is designed that when in a molten state, it can
be extruded onto the road surface to give an even line of good definition.
In order to give good drainage characteristics, a drainage channel may be
incorporated into the line at predetermined intervals.
Immediately following application of the line, a surface application of solid
glass beads to
IS EN 1423 or equivalent shall be applied at a typical rate of 450 g/m2 by an
applicator gun attached to the screed machine.
Lines are tack free within 2 minutes at an ambient air temperature of 15
This process employs a mechanically propelled vehicle. Extrusion utilises an
auger or pump from a thermostatically controlled tank to extrude the hot
thermoplastic through a gate opening set to produce a line of pre-selected
thickness of material onto the road surface. Glass beads are automatically
applied to the molten line. For more details refer to our Thermoplastic
Extrusion Method Statement.
Generally used on new road construction projects, asphalt, tarmacadam and
surface dressed roads.
Extrusion Thermoplastic is supplied in 25kg low melt polythene sacks. Each bag
is 25kg of powder mixture and supplied in 1.5 tonne batches, covered and stretch
wrapped for protection.
- Enhanced wet night visibility
- Immediate retroreflectivity
- Low maintenance costs – single application of sprayed thermoplastic
material immediately restores the Luminance & Retroreflective properties of
White and Yellow
