Dongguan Royflexa Rubber Co., Ltd. is an export-oriented, comprehensive and diversified large-scale private enterprise, taking the production of paper, gasket materials of flexible graphite, asbestos & asbestos-free materials, carbon black, and gasket & packing as the pillar industry, while also engaging in foreign trade, real estate, and scientific research simultaneously.
Since its establishment in 1996, by flexible management and continuous innovation, the group has achieved significant development—from a trading company to a business entity mainly engaged in scientific research and production. Our focus on Cork Rubber Specialty Insulation stems from a global demand for sustainable yet high-performance industrial materials.
The Cork Rubber Specialty Insulation market is experiencing a CAGR of over 5.8% globally. As industries transition towards "Green Construction" and "Electric Mobility," the demand for natural cork combined with resilient rubber has skyrocketed.
Modern trends emphasize Circular Economy principles. Our cork-rubber blends are increasingly used in EV battery thermal management, vibration damping in aerospace, and acoustic barriers in urban architecture.
Global procurement teams now prioritize E-E-A-T compliant manufacturers who can provide ISO-certified traceability, fire resistance ratings (UL94), and REACH/RoHS compliance for international export.
We spare no effort to introduce international standardized management systems into our company. Our group has successfully passed ISO quality, environmental, occupational health, and safety management system certifications, improving product quality, environmental protection, production safety, and overall management level, and bringing the company onto an internationally standardized management track.
Paper, gasket materials of flexible graphite, asbestos & non-asbestos, carbon black, gasket & packing, and related products are all produced with world-class equipment and advanced manufacturing techniques imported by our company. These products offer reliable quality and competitive pricing. With a 60% increase in sales, our products have rapidly occupied markets both domestically and internationally and enjoy a strong reputation, earning wide recognition and praise.
Used as thermal insulation for flooring and acoustic underlayment in LEED-certified buildings across Europe and North America.
Perfect for oil pan gaskets, valve covers, and transmission sealing where high vibration and heat resistance are required.
Highly resistant to saltwater and UV, making it the primary choice for deck insulation and mechanical room sealing.
Premium cork rubber sheets for ergonomic sandal footbeds and orthopedic inserts, combining comfort with durability.
Heavy-duty sealing for transformers and chemical processing equipment requiring chemical stability and low gas permeability.

All staff members of Dongguan Royflexa Rubber Co., Ltd., with renewed vigor and great enthusiasm, sincerely welcome friends and clients from all over the world to establish extensive cooperation and create a brilliant future together.
As a leading Cork Rubber Specialty Insulation Factory, we offer vertical integration that few can match. From raw material sourcing to the final precision-cut gasket, our process is optimized for both small-batch custom prototypes and high-volume industrial production. China’s supply chain efficiency allows us to source the highest quality natural cork from sustainable Mediterranean forests and combine it with advanced synthetic rubbers engineered for extreme conditions.
Our R&D team continuously experiments with hybrid insulation composites. By integrating carbon fiber, ceramic fibers, and flexible graphite into our cork-rubber matrices, we produce "Specialty Insulation" that withstands cryogenic temperatures as well as high-heat industrial environments. This expertise is why global leaders in the energy and automotive sectors trust Dongguan Royflexa as their primary OEM partner.
