Cost Efficiency
& Decarbonization
As the automotive industry accelerates toward the "Four Modernizations" — electrification, connectivity, intelligence, and sharing — lightweighting has become a core strategy to overcome cost constraints and environmental challenges. Studies indicate that a 1% reduction in vehicle weight can lead to a 0.7% decrease in fuel consumption and a 0.3%–0.5% reduction in carbon emissions. As an innovator in polymer materials, Crerax Technology is providing revolutionary lightweight solutions to automotive manufacturing through its core product — Crerax expandable microspheres.
A Game-Changing Engine for Lightweighting
Crerax microspheres are polymer additives with thermal expansion properties. Their unique structure consists of a polymer shell encapsulating a blowing agent. When heated, the volume of the microspheres can expand by 80–100 times, resulting in an ultra-low density of 30 kg/m³ (0.03 g/cm³), making them an ideal lightweight filler and foaming agent for plastics, rubber, and other materials.
Panorama of Lightweight Applications in Automotive Manufacturing
In the automotive sector, Crerax microspheres create value through:
√ Multi-Material Compatibility:Can be incorporated into mainstream automotive materials such as PP/PE, PA, ABS, polyurethane, and EPDM rubber.
√ Weight Reduction in Key Components:Widely used in door panels, instrument panels, GMT headliners, sealing strips, and anti-chip coatings.
√ Performance Enhancement:Significantly reduces material density while minimizing warpage and shrinkage deformation of molded parts, and improves dielectric properties.
Four Major Breakthroughs Compared to Conventional Processes
Compared to chemical foaming agents or supercritical foaming technologies, Crerax microspheres offer significant advantages:
◆ Process Simplification: Low equipment requirements and precise control of foaming temperature.
◆ Cost Optimization: Reduces raw material consumption and processing energy consumption.
◆ Performance Assurance: Maintains mechanical strength of materials and extends component lifespan.
◆ Environmental Safety: Physical foaming process releases zero harmful substances.
Continuing to Enable Automotive Industry Advancement
Crerax Technology remains committed to advancing microsphere technology and building a new materials ecosystem that spans over 130 industries. In the automotive sector, we will continue to promote:
● Synergistic achievement of body weight reduction and energy efficiency improvement.
● Dual breakthroughs in extended driving range and reduced carbon emissions.
● Integrated enhancements in driving quality and environmental benefits.
