PU Wood Imitation Casting Material

Two-component PU wood imitation casting material — reproduces natural wood grain for decorative mouldings, balustrades, cornices & carved furniture. Customizable density 250-1000 kg/m³, Shore A ≥80, ~95% closed-cell, weather- & insect-resistant.

Our two-component PU wood imitation casting material is a high-density polyurethane system that reproduces natural wood grain, colour and texture for decorative mouldings, balustrades, cornices and carved furniture. With a simple 1:1 mixing ratio and a density that can be tailored from ~250 up to 1000 kg/m³, it delivers lightweight trim or dense, carvable structural profiles — weatherproof, insect-proof and far more durable than real wood.

Tailorable density 250–1000 kg/m³
From lightweight trim to dense, carvable structural mouldings — made to your spec.
Weather resistant
Resists UV, moisture and temperature change — will not fade, crack or warp like real wood.
Anti-corrosion & insect-proof
Immune to fungi, mould and insects for a long service life.
Lightweight & workable
Light to handle; can be sawn, drilled, nailed, carved and painted like wood.

Processing & How to Use

1

Prepare the mould
Use a mould with the desired wood grain/profile; condition materials to ~20 °C.

2

Mix
Combine premixed polyol and MDI at 100:100 (1:1 by weight); stir 10–15 s, by machine or hand.

3

Pour
Cast into the mould — cream 30–60 s, gel 75–150 s, tack-free 100–210 s.

4

Demould & finish
Demould the cured part; saw, drill, carve, sand, stain or paint as needed.

Packaging, Storage & Handling

Packaging
Polyol in 200 kg net iron drums; MDI in 250 kg drums. Palletised for export; bulk on request.
Storage
Store sealed in a cool, dry, ventilated area away from moisture. Shelf-life details available on request.
Handling & Safety
Avoid eye/skin contact; wear safety glasses. Wash skin with soap and water; flush eyes with water and seek medical attention. Full MSDS on request.

Project Reference

Wood-imitation polyol raw material shipped to a US decorative moulding customer

Wood-imitation raw material shipped to a US decorative-moulding customer

United States — Decorative Moulding Producer

A US customer producing decorative mouldings and trim required multiple high-density grades of wood-imitation polyurethane. BlendPolyol formulated and supplied the system in three densities to match their profile range, and shipped the full polyol + MDI package to the United States.

Frequently Asked Questions

What densities are available?The standard grade is ~250 kg/m³; we also supply 300, 500 and 1000 kg/m³ grades on request, or any density formulated to order.
What is the mixing ratio?Premixed polyol to MDI at 100:100 — a simple 1:1 ratio by weight, for high/low-pressure machines or manual casting.
Can it be carved and painted like wood?Yes — cured parts can be sawn, drilled, nailed, carved, sanded, stained and painted just like natural wood, with higher strength and durability.
Is it suitable for outdoor use?Yes. With ~95% closed-cell structure it is weather-, moisture- and insect-resistant for interior and exterior decoration.
Can the formulation be customized?Yes. Density, hardness, colour and reactivity can be tuned to your moulds. OEM/ODM supported — request a TDS, MSDS and free sample; we reply within 24 hours.
