SHOCK CORD GUIDE
What Is Shock Cord?
Shock cord is an elastic cord made with a stretchable latex core and a braided outer sheath. It is widely used for fastening, securing, and absorbing movement in outdoor, marine, cargo, and industrial applications.
- Latex elastic inner core
- Braided protective outer sheath
- Strong stretch and recovery performance
how do bungee cords work
Shock cord works by combining an elastic inner core with a braided outer sheath. When the cord is stretched, the latex or rubber core provides the recovery force.
The outer sheath helps protect the core, improves abrasion resistance, and gives the cord its finished appearance. This structure makes shock cord useful for flexible tension, secure fastening, and repeated stretch recovery.
| Part | Function |
| Inner Core | latex elastic cord provide stretch and recoil |
| Outer Sheath | Braided sheath protects the core and resists abrasion and UV. |
| Diameter | Various diameters offer different strength and stretch ranges. |
| Material Choice | Sheath and core materials are selected for the intended environment and use. |
What Is Shock Cord Made Of?
Shock cord is typically made of two main parts: an elastic inner core and a braided outer sheath. The core provides stretch and recovery, while the sheath protects the cord and improves durability.
Inner Core
Natural Latex
Local natural latex
Synthetic rubber
Rubber
Outer Sheath
Polypropylene (PP)
Polyester (PET)
Nylon (PA)
UHMWPE
Polyethylene (PE)
Common Types of Shock Cord
Different shock cords are built with different combinations of inner core and outer sheath materials. These combinations affect stretch performance, durability, surface feel, and application suitability.
Nylon + Imported Latex
A premium construction with strong elasticity, smooth surface feel, and reliable rebound performance.
Polyester + Latex Core
A balanced choice for outdoor and industrial use, offering durability and stable stretch performance.
Polypropylene + Rubber
A practical and economical option for basic elastic cord applications and large-volume production.
Custom Material
Shock cord can be customized with different sheath and core materials based on application, budget, and performance targets.
