Cost Efficiency
& Decarbonization
In the global footwear industry’s relentless pursuit of innovation and excellence, Crerax Microspheres have emerged as a core driver of the lightweighting revolution in shoe materials. As a leading enterprise with years of expertise in high-performance expandable microspheres, Crerax has consistently invested in independent R&D and technological breakthroughs, offering comprehensive upgrade solutions for global footwear manufacturers. This supports the industry’s transition toward a new era of lighter, more comfortable, and more environmentally friendly products.
Crerax Microspheres: Core Technology and Innovative Breakthroughs
Crerax Microspheres are thermoplastic hollow polymer spheres composed of a thermoplastic polymer shell encapsulating a blowing agent. This unique structure provides outstanding performance: when heated, the shell softens and the internal pressure increases sharply, leading to expansion of the microspheres, with volume increasing by 80 to 100 times. The expanded microspheres can achieve densities as low as 20 kg/m³, making them an ideal lightweight filler and blowing agent for various materials including plastics and rubber.
Since establishing its expandable microsphere laboratory in 2008, Crerax has remained committed to independent innovation, dedicating significant resources to technological advancement. Through persistent effort, Crerax broke the foreign monopoly on microsphere technology, achieving domestic substitution and resolving a critical “bottleneck” issue in this field. To date, Crerax has applied for over one hundred patents and is recognized as a National High-Tech Enterprise and a Specialized, Refined, Unique, and New “Little Giant” Enterprise.
Outstanding Performance of Crerax Microspheres in Footwear Materials
1. PVC Shoe Materials: Synergistic Effects for Enhanced Quality
In PVC shoe material applications, Crerax Microspheres work synergistically with AC blowing agents to significantly improve foam cell structure. By forming uniform and dense cells, they not only enhance the support and stiffness of the material but also improve the overall quality and durability of finished shoes. The closed-cell structure of Crerax Microspheres effectively reduces injection molding defects and increases product yield, helping manufacturers boost production capacity by up to 20%. Furthermore, the short molding time and ease of shaping during processing further optimize production efficiency and reduce costs.
2. TPR Shoe Materials: Ideal Combination of Lightweight and Eco-Friendly Properties
Crerax Microspheres also demonstrate strong advantages in TPR shoe materials. With the addition of microspheres, the density of TPR materials can be significantly reduced to as low as 0.5 g/cm³, while maintaining uniform and compact cell structure, providing superior lightweight performance. The use of microspheres also effectively reduces shrinkage and deformation, improves surface fullness, and enhances the aesthetic appeal of shoes. Notably, as a physical blowing agent, Crerax Microspheres are more environmentally friendly compared to traditional chemical blowing agents, aligning with the global footwear industry’s growing emphasis on sustainability.
Comprehensive Upgrade and Empowerment: Supporting the Global Footwear Industry
In addition to excellent performance in PVC and TPR materials, Crerax Microspheres also provide complete solutions for other shoe materials such as rubber, TPU, and CPU. Through compatibility with various material systems, Crerax enables global footwear manufacturers to explore more innovative possibilities and develop more competitive products.
As market demands become increasingly diverse, consumers are placing higher requirements on comfort and environmental sustainability. Crerax Microspheres help manufacturers meet these expectations by delivering lightweight, eco-friendly characteristics, resulting in high-quality footwear that offers enhanced comfort and a reduced environmental footprint. Moreover, the application of Crerax Microspheres brings significant economic benefits to the industry—increasing production capacity and reducing costs—helping companies gain a competitive edge in the market.
Looking Ahead: Continuous Innovation Leading New Transformation in Footwear Materials
As a globally leading manufacturer of high-performance expandable microspheres, Crerax will continue to uphold an innovation-driven philosophy, increasing investment in R&D, and introducing more high-performance and multifunctional microsphere products. In the future, Crerax Microspheres will play an even greater role in the footwear lightweighting revolution, providing strong technical support and innovative momentum for the development of the global footwear industry. At the same time, Crerax remains committed to delivering high-quality and innovative footwear products to consumers, promoting a greener and more sustainable future for the industry.
