AUTOTHANE™ is a high performance microcellular polyurethane system based on hybrid polyols and MDI technology from Dow Hyperlast. It has been specifically developed for impact, shock and vibration management in automotive applications.

AUTOTHANE™ offers OEM and Tier 1 design engineers high performance solutions to technical problems in suspension design, performance and vibration control. The AUTOTHANE™ system offers:

• High tensile and tear strength
• Low temperature flexibility (Tg of -63°C)
• High resistance to repeated compression
• Progressive load deflection characteristics

AUTOTHANE™
• Easy to process
• Cost effective
• Offers a short in-mould time
• Is designed for high-quality, high-volume automated moulding processes
• Conforms to current automotive specifications for high-stress components
• Has over 12 years history of service on vehicles

The majority closed cell structure and integral skin gives components moulded in AUTOTHANE™:
• High abrasion resistance
• Excellent hydrolytic stability
• Resistance to microbial degredation
• Improved damping characteristics
• Longevity of “on vehicle” performance

These properties make AUTOTHANE™ components ideal for use in numerous automotive chassis, suspension and NVH (Noise, Vibration and Harshness) applications:

• Spring Aids in McPherson Strut type designs on cars, trucks, vans, SUV’s, motorcycles and snow mobiles.
• Bump stops in Leaf Spring suspension designs
• Suspension top mounts
• Suspension spring seats
• Body and cab mounts
• Seat damping
• Bush stiffeners
• Vibration Isolating washers and bushes

For many years, design engineers have been making use of the unique mechanical and dynamic properties of high density microcellular polyurethane elastomers. When used in suspension systems or vibration isolation applications, these materials are known to improve a vehicles handling, comfort and ride quality. The AUTOTHANE™ microcellular
polyurethane technology combines these benefits to meet engineers needs in NVH applications.
