PolyBak Laserboard Ivory PB67 Engineering Board

The High Performance Standard for Intricate Detailing and Precision Laser Cutting

PolyBak PB67, which is often referred to as ivory laserboard, is a high performance, polymer impregnated Kraft liner board engineered for exceptional structural integrity in thin gauge applications. Originally developed as a balancing backer for the veneer industry, this 0.4mm thick material has become a definitive choice for professional model making due to its incredible strength, flexibility, and resistance to heat and moisture. Unlike standard cardboards or greyboards, PolyBak remains completely rigid and durable even when intricate patterns or large surface areas are removed, providing a high fidelity alternative to traditional oiled manilla and thin MDF.

Why Model Makers Choose PolyBak PB67

• Intricate Detailing Performance: It is the primary choice for ultra fine details such as window mullions, decorative screens, and complex facade overlays. It cuts beautifully using a laser cutter without leaving excessive burn marks or charring, which significantly reduces your post production cleaning time.
• Retains Structural Integrity: The specialised polymer impregnation ensures that the material does not tear, warp, or become brittle when you cut away large sections or extremely thin lines.
• Versatile Finishing Options: The smooth, ivory surface provides a neutral, sophisticated finish that can be used raw or treated. It is highly receptive to painting, staining, and varnishing, and its durable face ensures that masking tape will not damage it during the fabrication process.

Working with PolyBak PB67

• Precision Cutting: The material scores easily with a sharp craft knife or scalpel for manual tasks. However, the cleanest and most accurate results come from laser cutting, which produces incredibly sharp, soot free edges.
• Durable Gluing: PolyBak readily bonds to a wide variety of workshop substrates, including MDF, plywood, acrylic, or foam. It is fully compatible with standard hot or cold setting adhesives such as PVA, universal glues, and contact cement.
• Shaping and Bending: Because of its unique resin impregnated composition, you can slightly dampen or gently heat the material to form gentle curves and architectural arches. The material will reliably hold its new shape once it has cooled and set.

Technical Expert Tip

While raw PolyBak accepts colour beautifully, applying a high quality primer as a base coat before your main paint layers is highly recommended. This seals the polymer matrix and ensures a completely dense, uniform colour finish across your finished model assemblies.
