Expo 0.50mm (20 thou) Thick White

The Expo 0.50mm (20 thou) Thick White Sheet is a styrene plastic sheet pack used widely in scale modelling for scratch-building, structural reinforcement, and detailed conversions.

This pack contains 3 sheets, each measuring 228 × 330mm, made from rigid white polystyrene that can be easily cut, shaped, and glued using standard model adhesives.

About the material

At 0.50mm thickness, this styrene sheet is more rigid than thinner grades, making it suitable for applications where strength and structural stability are required while still remaining workable for hand tools.

It is commonly used in both aircraft, armour, and diorama modelling for building or reinforcing components.

• vehicle armour plates and hull extensions

• aircraft interior frameworks

• diorama base structures and buildings

• reinforcing kit parts during conversions

Skill level

Beginner to Advanced

Suitable for all levels:

• beginners: simple structural additions

• intermediate: kit modifications and scratch details

• advanced: full conversions and complex scratch builds

Application tips

• Use a sharp hobby knife for clean scoring and cutting

• Score multiple light passes before snapping

• Use liquid cement for strong, seamless bonds

• Sand edges for precision fitting

• Combine with thinner sheets for layered detailing

Ideal for
