Hongjie manufactures custom Neoprene (CR/polychloroprene) rubber parts for OEM applications requiring flame resistance, sulfur-free compounds or strong rubber-to-metal bonding. Since 2001, our 11,000 m² Shenzhen facility has molded and extruded CR components for automotive, appliance and industrial buyers in more than 45 countries.
Polychloroprene resists ozone and weathering well, bonds to metal more readily than most elastomers, and self-extinguishes rather than sustaining flame — but oil and fuel resistance is only moderate, where NBR and FKM perform better. Compare against EPDM rubber parts for weather-only applications or NBR rubber parts where fuel resistance matters more than flame safety.

Molded, extruded and bonded CR components for sealing, pass-through protection, vibration isolation and OEM assemblies.
Panel pass-through grommets that protect cables and help isolate vibration in equipment housings.
Flange and housing gaskets produced for static sealing, weather exposure and moderate chemical contact.
Static and dynamic sealing profiles for doors, panels, housings and moving assemblies.
Continuous CR strips and channel profiles cut to length for weatherstripping and enclosure sealing.
Bonded mounts and structural components that combine CR flexibility with the strength and stability of metal inserts.
