The Gold Standard in Traffic Supply Products

Preformed thermoplastic has revolutionized road marking systems worldwide, offering unmatched durability, reflectivity, and efficiency compared to traditional paint solutions. As cities expand and traffic volumes increase, the demand for long-lasting, high-visibility road markings has made preformed thermoplastic the material of choice for transportation authorities globally.

This comprehensive guide explores the composition, benefits, installation methods, and international applications of preformed thermoplastic markings, along with emerging innovations in the field.

What is Preformed Thermoplastic?

Preformed thermoplastic is a pre-manufactured, solid road marking material composed of:

  • Thermoplastic resin (35-45%)
  • Glass beads (30-40% for reflectivity)
  • Pigments (15-25% for color)
  • Fillers and additives (5-10%)

Unlike liquid-applied thermoplastics, preformed versions come as pre-cut shapes, symbols, or line segments that are heat-fused to the pavement surface.

Key Properties:

  • Melting point: 180-220°C (356-428°F)
  • Service life: 3-8 years (vs. 6-24 months for paint)
  • Reflectivity: Initial retroreflectivity of 300-500 mcd/m²/lux
  • Skid resistance: 45-65 BPN (British Pendulum Number)

Types of Preformed Thermoplastic Markings

1. Pre-cut Line Markings

  • Standard widths: 100mm, 150mm, 200mm
  • Used for lane dividers, edge lines, and centerlines

2. Preformed Symbols

  • Pedestrian crossings, arrows, bike symbols
  • Regulatory signs (STOP, YIELD, etc.)

3. Custom Shapes

  • Roundabouts, complex intersections
  • Airport runway markings

4. Anti-Skid Variants

  • Contains aggregate additives for wet-weather traction
  • Common in Nordic countries and mountainous regions

Global Applications and Standards

North America

  • FHWA-compliant formulations dominate US highways
  • MUTCD standards govern color and dimensions
  • Canada uses modified versions for snowplow resistance

Europe

  • EN 1871 specifies performance requirements
  • Germany and UK lead in innovative applications
  • Nordic countries use high-friction versions for winter safety

Asia-Pacific

  • China’s expressways use 8-10mm thick thermoplastics
  • Australia’s AS 4049.3 governs performance standards
  • Japan employs earthquake-resistant formulations

Middle East

  • Modified thermoplastics withstand 60°C+ pavement temps
  • UAE and Saudi Arabia prefer high-reflectivity versions

Installation Process

Surface Preparation

  1. Cleaning: High-pressure washing or mechanical brushing
  2. Priming: Application of specialty primer (for porous surfaces)

Application Methods

  • Torch Application: For small repairs and symbols
  • Heating Machine: For long line segments
  • Specialized Applicators: For complex patterns

Curing and Traffic Opening

  • Cooling time: 3-5 minutes (vs. 15-30 min for paint)
  • Immediate traffic readiness
