High-Density PU for 3D Decorative Wall Panels
Two-component high-density self-skinning PU for moulding 3D decorative wall panels — quilted, relief & geometric cladding. Moulded density ~250 kg/m3, Shore A >=80, leather-look surface.
A two-component high-density self-skinning polyurethane system for moulding 3D decorative wall panels — quilted “soft-pack”, relief and geometric wall cladding. The cured PU forms a tough, leather-look skin over a firm core (density ~250 kg/m³, Shore A ≥ 80), giving lightweight, durable panels that are easy to install and finish in any colour. Sound-absorbing, flame-retardant and hard-wearing for homes, hotels and commercial interiors.

Key Features
Self-skinning leather look Forms a smooth, tough outer skin over a firm core in one shot — no separate facing needed.
Crisp 3D detail Reproduces quilted, relief and geometric mould textures with sharp edges.
Lightweight & easy to install Far lighter than stone or plaster — glue-up panels cut and fit easily.
Durable & hard-wearing Shore A ≥ 80 with good impact and compression strength resists knocks and dents.
Sound-absorbing & warm The cellular core dampens noise for quieter, cosier interiors.
Colourable & flame-retardant Mouldable in any colour and formulated for good flame retardancy.

Processing
Low-Pressure Casting Pour the two components into the 3D panel mould on a low-pressure PU machine.
Self-Skin Moulding Forms a dense skin against the mould wall — demould in minutes.
In-Mould Colour Add pigment for any base colour; surface can be sprayed / foiled afterwards.
Machine Compatible Runs on low- and high-pressure PU foaming machines.

3. Scale to bulk Confirm the formula and order in bulk with flexible MOQ and tiered lead times.
Frequently Asked Questions
Is this a finished panel or a raw material?It is a two-component raw-material system (polyol + isocyanate). Cast into a 3D mould, it self-skins into a finished decorative wall panel.
Why a self-skinning PU panel vs. PVC or gypsum?PU self-skins into a tough leather-look surface in one shot, is lighter and more impact-resistant than gypsum, and reproduces crisp 3D detail — with sound absorption and flame retardancy.
Can colour, hardness and density be customised?Yes. In-mould pigment gives any base colour; density (~250 kg/m³) and hardness (Shore A ≥ 80) are tunable by formulation.
Do you supply moulds and machines too?Yes — matched low-pressure PU machines and 3D panel moulds are available so you can produce panels in-house. We reply within 24 hours.
