Ethylene Propylene Rubber – EPR cables

Product Details: EPR (Ethylene Propylene Rubber) and EPDM (Ethylene Propylene Diene Monomer) are thermosetting elastomeric compounds used in cable insulation and sheaths. EPR is a copolymer of ethylene and propylene, while EPDM is a terpolymer including a small amount of non-conjugated diene monomers for cross-linking. These materials are used in low and medium voltage cables, with EPR preferred for higher voltage applications due to its superior electrical performance. They are compounded with fillers, vulcanizing agents, and other additives to enhance their properties. Both EPR and EPDM are applied using conventional single screw extruders and then cross-linked through vulcanization processes.

Frequently Asked Questions (FAQs)

Frequently Asked Questions About EPR (Extended Producer Responsibility) in China

What is Extended Producer Responsibility (EPR) in China

EPR in China is a policy that makes producers responsible for the entire lifecycle of their products, including design, consumption, recycling, and waste disposal. This approach aims to reduce resource consumption and environmental impact.

Which products are covered under China’s EPR plan

China’s EPR plan initially focuses on electronics, automobiles, lead-acid batteries, and packaging products. It also extends to home appliances such as TVs, refrigerators, washing machines, and air conditioners. The goal is to ensure these products are recycled and disposed of responsibly.

What are the key responsibilities of producers under EPR

Producers are tasked with establishing waste recycling systems, designing products with environmental impact in mind, increasing the use of recycled raw materials, unifying recycling efforts, and enhancing information disclosure. They must also set and achieve recycling targets and submit annual reports on their progress.

How does the Chinese government support EPR implementation

The government encourages participation through incentives such as priority support for projects that promote structural transformation and innovation. Companies that meet recycling targets are added to the “Green Enterprise List” and receive priority support for green bonds and loans.

What are the targets and timelines for EPR implementation in China

By 2025, China aims to achieve a 50% recycling rate for key products and a 20% utilization of recycled raw materials. The National Development and Reform Commission and the Ministry of Ecology and Environment have set timely targets for 2020, 2022, and 2025 to control plastic pollution and promote recycling in various sectors.
