Frequently Asked Questions (FAQs)

What is EPDM rubber and how is it used in Chinese factories?

EPDM (Ethylene Propylene Diene Monomer) rubber is a synthetic rubber known for its excellent resistance to heat, ozone, and chemicals. In Chinese factories, EPDM rubber is widely used to manufacture various products such as seals, gaskets, hoses, and other industrial rubber components. It is particularly popular in the automotive, industrial equipment, and construction industries due to its durability and versatility.

Which Chinese companies are major producers of EPDM rubber products?

Several Chinese companies are prominent in the production of EPDM rubber products. For instance, Guanlian is one of the largest rubber compounders in China, offering a wide range of rubber solutions including EPDM. Another notable company is Hebei Shida Seal Group, which specializes in manufacturing molded rubber products, including those made from EPDM, and serves various industries such as automotive, industrial equipment, and more.

What kind of manufacturing processes do Chinese EPDM rubber factories use?

Chinese EPDM rubber factories employ advanced manufacturing processes such as compression molding and injection molding. Compression molding involves placing preheated, uncured rubber into a heated mold and applying pressure until the rubber is fully cured. Injection molding, on the other hand, involves injecting melted rubber into a mold, which is faster and more suitable for high-volume production. These processes ensure high-quality and precise rubber parts.

How do Chinese EPDM rubber factories ensure quality and compliance with industry standards?

Chinese EPDM rubber factories, such as Hebei Shida Seal Group, adhere to strict quality standards. Many of these factories are certified with IATF 16949:2016, which is a global standard for the automotive industry. They also use the latest equipment and technology, and offer in-house tool and mold design and manufacturing to ensure that the products meet the most exacting requirements. Additionally, they provide value-added finishing services and supply PPAP (Production Part Approval Process) and process control documentation.

What steps are Chinese EPDM rubber factories taking to reduce their environmental impact?

Chinese EPDM rubber factories are increasingly focusing on reducing their environmental impact. For example, Guanlian has invested in advanced air-purifying equipment and automated operating and monitoring systems to prevent emissions of dust, oil-mist, odor, and other discharges. These factories also align their operations with national and local environmental policies, ensuring that their growth is sustainable and environmentally friendly. This includes initiatives to minimize CO2 footprint, especially in new facility setups.
