8. Underbody coating (UBC)
In vehicle applications
Expancel® Microspheres - Your engineered solution
8
• The purpose of UBC is to reduce noise and protect
the underbody against environmental influences
• Typical weight of UBC without lightweight filler is
around 8 kg per car
• During storage, pumping, and spray application
pressures up to 350 bar (5076 psi) can occur
• The UBC ingredients need to be resistant to
pressure as well as plasticizers like DINP
• The same conditions apply to seam sealants

9. Challenges of tomorrow
The global trends
Expancel® Microspheres - Your engineered solution
9
• Automotive manufacturers must comply with
stricter regulations to reduce CO2 emissions
• Increased consumer demand for vehicles with
a low CO2 footprint without compromising on
performance and convenience
• The automotive industry is under constant pressure
to reduce production costs
• EV and ICEV need to improve the driving range
• Even lighter materials required
• Reduction of UBC and sealant density needed

10. Limitations of today
The current technologies
Expancel® Microspheres - Your engineered solution
10
• If added in higher amounts, glass bubbles fail to
meet the physical elasticity needed for sealants
• Automation lines cause shear stress resulting in
destroyed glass bubbles and wear on equipment
• Current thermoplastic microspheres fail during high
pressure, resulting in increased density and poor
surface appearance

11. Combining the best of two worlds
Expancel® Microspheres - Your engineered solution
11
• High volume recovery and high-shear
stress-resistant to work in manufacturing processes
• Combined with ultra-low material density
The result is an ultra-light UBC coating or seam sealant,
without compromising on physical product performance
Introducing Expancel® HP92 Microspheres

12. Expancel® HP92 Microspheres - the resistant grade
Optimized for high pressure applications
Expancel® Microspheres - Your engineered solution
12
• Thermoplastic microspheres are prone to buckling
when pressurized
• At very high pressures “legacy grade”
microspheres can get destroyed
• Expancel® HP92 Microspheres exceptional
stability allows for a more than 4 times better
recovery to its original shape after pressurization
even in DINP
