Ultrathane Polyurethane

Ultrathane polyurethane is one of the most versatile of modern engineering materials. It incorporates hardness, resilience, strength and abrasion resistance

Ultrathane polyurethane’s versatility enables cost effective solutions for short production runs and prototyping.

It is available in a hardness range 25A-84D shore, and can be supplied in rod, sheet, tube or moulded to your requirements. For more information please contact us.

Applications for Ultrathane polyurethane within engineering are many and varied. General advantages of using Ultrathane polyurethane:

• Abrasion resistant
• High impact strength
• Oil and chemical resistant
• High load carrying ability
• Wide range of hardness 25A – 84D
• Operating temperatures to120C
• Good elastic memory
• Good dynamic properties
• Low coefficient of Friction
• Easy to machine
• Noise reduction
• Resistant to environmental degradation

Typical Physical Properties of Ultrathane polyurethane:

Hardness Shore A	83	95
Tensile (Mpa)	49	38
Elongation %	600	350
Modulus 300%(Mpa)	9.7	28
Split Tear (KN/m)	22	22
Rebound %	31	42
Compression Set % 24hrs	35	32
Specific Gravity	1.3	1.1

Physical properties of polyurethane can be manipulated by changing or varying several factors including processing conditions and type or quantity of polyol, isocyanate, curative or additives used. By varying these constituents, specific values such as hardness or tensile strength can be achieved.
