Polyurethane (Polyurethane) for resin, foam & gel
Polyurethane (PU, PUR; EN: polyurethane, DE: polyurethane) is an extremely versatile polyurethane material that combines the best properties of rubber and plastic. From polyurethane resin for castings to polyurethane foam (PU foam) and polyurethane gel for damping and sealing: choose precisely the Shore hardness and processing method that your application requires.
⚠️ Please note (safety & regulations)
Since August 2023, polyurethane with a diisocyanate content >0.1% may only be processed in companies where employees have completed the required training. Inquire within your organization about the appropriate online course and ensure certification before starting.
Companies can register for an online training via THIS link.

Why choose polyurethane (polyurethane material)?
- ✓ Wear-resistant & tear-resistant: up to many times more durable than conventional plastics in dynamic applications
- ✓ Wide hardness range: from soft elastomer (Shore A) to hard plastic (Shore D)
- ✓ Chemical resistance: resistant to oils, fuels and many solvents
- ✓ Precision & stability: low shrinkage, dimensionally stable; easy to process and paint after curing
- ✓ Process selection: casting, foaming, coating, bonding – including 2-component systems
Product families: polyurethane resin, foam & gel
Polyurethane Resin (PU Casting Resin)
For functional castings, molds, prototyping, and wear-resistant parts. Available as hard Shore D (structural parts) or flexible Shore A (rubbery).
- Advantages: fast curing, high impact resistance, dimensionally stable
- Applications: gears, bumpers, wheels/rollers, couplings, mold components
Polyurethane Foam / PU Foam (Polyurethane Foam)
Lightweight polyurethane foam for insulation, filler, and molded parts. Adjustable for density and cell structure.
- Advantages: low weight, cushioning, thermal insulation
- Applications: core material, protective and packaging foam, moulded foam
Polyurethane Gel (Polyurethane Gel)
Very soft, tough gel for cushioning, sealing, and vibration absorption. Ideal as a soft-touch interface or encapsulant.
- Advantages: high energy absorption, sticky/adhesive surface if desired
- Applications: pads, seals, SFX/prosthetics, protection of electronics
2-component polyurethane adhesive - professional PU adhesives
For fast and strong bonding of metals, composites, and selected plastics, there are two-component polyurethane adhesive solutions (PU 2K adhesives). They combine a short open time with high final strength and toughness.
- Strengths: quick installation, impact resistant, good peel/shear
- Applications: automotive, mechanical engineering, panel bonding, repairs
Shore hardness: choose the right PU
| Range | Characteristic | Typical Bet |
|---|---|---|
| Shore A 10–95 | Soft to semi-hard, elastic | Seals, elastic parts, damping |
| Shore D 40–85 | Hard and stiff, plastic-like | Structural components, wear-resistant parts |
Polyurethane applications
- Industrial : conveyor rollers, bearings, guides, wear parts
- → Automotive: mufflers, bumpers, interior parts
- → Composites & Moulds: flexible/rigid moulds, core and edge reinforcements
- → Construction & insulation: PU foam (polyurethane foam) for thermal/acoustic functions
- → Prototyping: functional models, end-use parts
FAQ - Polyurethane definition & frequently asked questions
What is polyurethane? (polyurethane definition)
Polyurethane is a family of polymers formed by the reaction of polyols with (di)isocyanates. Depending on the formulation, polyurethane resin, polyurethane foam, or polyurethane gel are created with varying hardness and properties.
What is the difference between PU foam and PU resin?
PU foam (polyurethane foam) is a low-density, cellular structure used for insulation/filling. PU resin is solid and is used for sturdy castings and components.
Do I need training to process PU?
Yes, training is mandatory for systems containing >0.1% diisocyanate. Ensure employees are certified before working with PU.
