Polyurethane (PU) - The Ultimate Versatile Casting Material

Polyurethane , also known as PU or PUR , is a unique material that combines the best properties of rubber and plastic. From soft, elastic varieties to hard, strong plastics, polyurethane offers unparalleled versatility for professional and industrial applications.

Why Choose Polyurethane?

• Exceptional wear resistance: Up to 10x better than conventional materials
• High tear resistance: Resistant to extreme loads
• Excellent compressive strength: Ideal for heavy industrial applications
• Chemical resistance: Resistant to petrol, mineral oils, solvents and greases
• Resilient: Elastic and hard variants do not break easily
• Machinability: Can be easily painted and mechanically machined after curing.

Our Polyurethane Categories

🔧 Hard Polyurethane Shore D

Benefit: Extreme strength and dimensional stability for structural components, gears, and wear-resistant parts. Shore D values ​​of 40-85 for maximum durability.

🔄 Flexible Polyurethane Rubber

Benefit: Soft, elastic properties (Shore A) ideal for rubber-like applications, seals, flexible parts and applications requiring flexibility.

🎨 Polyurethane Dyes

Advantage: Professional coloring of your PU projects with UV-resistant pigments that maintain mechanical properties. Available in all RAL colors.

🧽 PU Foam

Advantage: Lightweight insulation and filler material with excellent thermal properties and flexibility. Ideal for design and insulation applications.

⚗️ Fillers

Advantage: Modifies PU properties such as density, fire resistance, and cost. Increases volume and can improve specific mechanical properties.

🛡️ Release agents

Benefit: Professional release agents for easy demolding of PU parts from molds. Prevents adhesion and extends the life of molds.

Shore Hardness Overview

• Shore A (10-95): Soft, flexible varieties - rubber-like properties
• Shore D (40-85): Hard variants - plastic-like properties

Areas of application

Polyurethane is widely used for:

• Industrial parts: Forklift tires, conveyor rollers, bearings and guides
• Automotive sector: Bumpers, spoilers and vibration-damping parts
• Mechanical engineering: Wear-resistant components and couplings
• Prototyping: Functional prototypes and end-use parts
• Mold and Mould Making: Flexible and Hard Molds for Reproduction
• Building and Construction: Insulation, Seals and Structural Elements

Professional PU Processing

For optimal results with polyurethane, the right additives are essential:

• Fillers: For cost savings, volume expansion and customized properties
• Release agents: For professional demolding without damage
• Colorants: For aesthetic and functional color applications
