Foam shoes

Foam shoesUsing PVC foam material to form a porous structure through the following two methods:

Chemical foaming: The foaming agent decomposes at high temperatures to produce gases (such as nitrogen and carbon dioxide), which expand in the PVC melt to form bubbles.

Physical foaming: using supercritical fluid (such as carbon dioxide) to dissolve in PVC under high pressure, and after decompression, gas escapes to form uniform bubbles.

The size, density, and distribution of pores directly affect the buffering, rebound, and support properties of the material, and require precise control through process parameters.

Foam shoesProduct function

Buffer protection: Absorbs impact force through deformation, protecting joints such as ankles and knees from sports injuries.

Stable support: A well-designed foam structure can provide moderate support, maintain the natural shape of the foot, and prevent excessive internal or external rotation.

Comfortable experience: Reduce the weight of the shoe body and alleviate fatigue during prolonged walking or running.

Cost optimization: Reduce material and manufacturing costs while ensuring basic performance, and improve product cost-effectiveness.

Precautions for use

Temperature limit: PVC foam material may soften and deform in high temperature environments, so avoid prolonged exposure to direct sunlight or high temperature places (such as car trunks).

Chemical compatibility: When transporting special chemical substances (such as strong acids and bases), it is necessary to confirm the material compatibility to prevent corrosion or performance degradation.

Installation specifications: When bending and laying, maintain the minimum bending radius to avoid excessive bending and damage to the internal structure; When laying underground, it is necessary to fill with fine sand or soft soil to prevent sharp objects from piercing.

Maintenance inspection: Regularly check the wear of the shoe sole, and replace it in a timely manner if there are cracks or deformations to prevent safety hazards.

Environmental protection treatment: After disposal, it is necessary to classify and recycle according to local regulations, avoid arbitrary incineration or landfill, and reduce environmental pollution.
