Enhance the mechanical properties of materials
After mixing EPS Particles with polymers, the mechanical properties of the material can be significantly enhanced. EPS Particles themselves have certain elasticity and toughness. When combined with polymers, they can serve as an effective reinforcing phase and are dispersed in the polymer matrix. When the material is subjected to external force, EPS Particles can bear part of the stress and prevent the expansion of cracks, thus improving the impact strength and compressive strength of the material. For example, in some building insulation boards, after EPS Particles are mixed with polymers, the boards not only have good thermal insulation properties, but can also withstand certain external impacts and are not easily damaged, extending the service life of the material.
Improve the thermal insulation properties of materials
EPS Particles have excellent thermal insulation properties and contain a large number of closed pores inside. The low thermal conductivity of air makes it difficult for heat to pass through. When mixed with polymers, this insulating property can be further developed and enhanced. As a continuous phase, the polymer wraps the EPS Particles, forming a relatively stable thermal insulation structure and reducing the heat transfer path. Therefore, the mixed material performs better in thermal insulation and can be widely used in areas with high requirements for thermal insulation such as building exterior wall insulation and cold chain logistics packaging, effectively reducing energy consumption and improving energy utilization efficiency. .
Improve material processing performance
During the processing of polymers, sometimes the processing efficiency and product quality are affected due to high viscosity or poor fluidity. The addition of EPS Particles can improve this situation. The spherical structure of EPS Particles gives it good fluidity and dispersion in polymers, and can act like a "ball bearing" to reduce the viscosity of the polymer and improve its processing fluidity. This makes the material smoother and easier to form during processing such as extrusion and injection molding, enabling the manufacture of products with complex shapes and precise dimensions, while also reducing energy consumption and equipment wear during processing.
Give materials special functional properties
In addition to the improvement of the above basic properties, mixing EPS Particles with polymers can also give the material some special functional properties. For example, by selecting EPS Particles with different particle sizes and surface properties, and adjusting the mixing ratio, the material can have certain sound absorption and noise reduction functions. In addition, specific functional additives, such as flame retardants, antibacterial agents, etc., can also be added to EPS Particles or polymers to make the mixed materials have special properties such as flame retardant and antibacterial to meet the special needs of different application scenarios and broaden the scope of Material application range.
