It features a lightweight, rigid polyurethane (PUR) foam core wrapped in paper coated, matt, white pigmented chromo replacement cardboard liners. Unlike standard polystyrene foam boards, KAPA line is engineered for exceptional workability. Its high density core resists crumbling when cut, accepts incredibly sharp lines, and allows the paper layer to be cleanly peeled back for carving custom textures, providing a highly stable substrate for high precision construction.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Professionals Choose KAPA line\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCrumble-Free Clean Cuts:\u003c\/strong\u003e The polyurethane core is significantly denser than standard foam boards. This prevents the edges from fraying or breaking into loose beads, yielding sharp, clean lines when slicing through intricate detail work.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdvanced Texture Carving:\u003c\/strong\u003e Unlike alternative foam boards, you can carefully peel off the paper liner and use modelling tools to emboss, sand, or carve the exposed PUR foam to create highly realistic brickwork, stone, or organic terrain features.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExceptional Structural Workability:\u003c\/strong\u003e The material integrates seamlessly with other professional papers and boards such as Bristol, offset, or screen printed card.

Applying treatment to only one side creates surface tension that will cause the board to bow or warp as it dries.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCreating Hand Carved Textures:\u003c\/strong\u003e Once the paper lining has been stripped away, you can use a wire brush, small dental tools, or a jewellers file to stamp patterns, engrave architectural lines, or distress the exposed polyurethane foam.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGluing and Layering Solutions:\u003c\/strong\u003e Standard PVA and spray adhesives work exceptionally well on the cardboard face. For maximum structural bonding on heavy joints, strip away a thin channel of the paper layer so your glue can bond directly to the high density foam core.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Lightweight PUR (Polyurethane) rigid foam core (Crumble resistant)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLiner Material:\u003c\/strong\u003e Chromo-replacement cardboard (Matt finish on both sides, white pigmented)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThickness Options:\u003c\/strong\u003e Available in multiple thickness variants\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Available in multiple sheet size configurations\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Bright White\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eArchitectural Model Making:\u003c\/strong\u003e Recognised as the optimum modelling material for scales ranging from 1:100 to 1:1, ideal for clean geometric massing, structural walls, and custom textured facades.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrototyping and Industrial Design:\u003c\/strong\u003e Perfect for creating lightweight yet highly rigid structural mock ups where components must slot together neatly without sagging.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVisual Communication and Display:\u003c\/strong\u003e A premium, smooth substrate for high resolution digital printing, point of sale signage, and professional photographic mounting.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFilm and TV Scenic Design:\u003c\/strong\u003e Widely used for constructing lightweight, camera ready set details and detailed miniature props that require painting with emulsion or spray paints.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eChoosing Between KAPA Line and KAPA Graph\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen selecting between KAPA line and KAPA graph for model making, the core difference comes down to aesthetics and surface finish.
