Recycled polypropylene supports epp's sustainable future! borouge rd209apc custom solution commercialized

Borouge 2025-07-18 09:45:03

Under the EU's ban on single-use plastic products (SUP) and China's "14th Five-Year Plan" promoting recycled plastics, the automotive and packaging industries are actively responding to the call for weight reduction and carbon reduction. They are developing products using innovative and recyclable materials, promoting sustainable development in the industry.

EPP (expanded polypropylene) due to its excellentSeismic energy absorption, deformation recovery, heat resistance, chemical corrosion resistance, oil resistance, and thermal insulation performance.The widely used characteristics of EPP, such as lightweight, excellent cushioning performance, and recyclability, have found applications in automotive parts (such as bumpers, seat cores, trunks, and foot mats), furniture, and turnover boxes. As global attention to sustainable development continues to deepen, EPP manufacturers are also actively exploring the feasibility of applying recycled polypropylene (rPP) in EPP foaming.

Challenge: Stability of recycled polypropylene quality

1 Characteristics requirements of EPP raw materials

EPP products have strict requirements for raw material performance during the molding process, especially regarding the stability of foaming ratio and bubble size. Therefore, EPP producers typically require that the melting point fluctuation be controlled within ±0.5°C, and the melt flow index be stable between 8 to 10 g/10min.

Recycling polypropylene quality stability

Due to the numerous manufacturers of polypropylene products in the market, even similar products may have significant differences in raw material types, resulting in the quality of recycled polypropylene being difficult to meet the above requirements.

Solution: Customized RD209APC Applied to Automotive Parts

Driven by the circular economy and carbon reduction goals, Bolu has actively invested in the application development of recycled materials. In response to technical challenges from a well-known EPP manufacturer, Bolu, led by the packaging department, integrated company resources over three years, streamlining the entire process from raw materials to products, and ultimately developed RD209APC.

Raw Material Quality Assurance

Bolok collaborates with downstream customers in the packaging department to secure the source of PIR (Post-Industrial Recycled) materials and completes extrusion granulation and product testing at the Shanghai Lingang factory to ensure the stability of raw material quality.

Confirmation of product specifications

During the product development process, the Lingang factory coordinated different production lines multiple times, optimized the extrusion granulation process, and established key quality control points. Ultimately, RD209APC passed several rounds of batch production validation, meeting the strict requirements for melting point and melt flow index set by EPP manufacturers, and was successfully applied to automotive components for a well-known international brand.

RD209APC has been successfully commercialized in internationally renowned automotive components, marking a solid step for Bolu in promoting the circular economy and the application of high-performance recycled materials.
