The company adopts extrusion method to produce R-EPS products. This production process can reprocess any proportion of recycled PS to produce R-EPS products (10-100% recycled PS), realizing the recycling of EPS recycled material to R-EPS through physical process, which has broad application prospect in the field of circular economy.

In terms of foaming process, we optimize the formula related to foaming and product performance, so that the EPS cell-size after pre-foaming and molding are sufficiently fine and uniformly distributed, with intact cells. At the same time, the process also enables the blowing agent and polystyrene system to mix homogeneously in supercritical state, realizing molecular level diffusion, and avoiding pre-foaming by using continuous high-pressure underwater pelletizing technology.

Compared with the performance of suspension method EPS, both of them have similar performance in terms of compression strength and puncture strength. However, under certain circumstances, R-EPS has better performance in terms of maximum load flexural strain and flexural stress under maximum load.

Comparison of the performance of recycled R-EPS and new EPS raw materials, the performance of the two is close.
