What is A Rubber Cord? How Does it Work?

A rubber cord is a flexible material made from different rubber materials. It is typically prevalent in sealing, cushioning, and vibration damping. Rubber cords can be stretched and compressed without breaking. They come in different shapes, including solid, hollow, and co-extruded. In the later part of this article, we will discuss these shapes elaborately.

The physical properties of cord rubber provide reliable and long-lasting performance. When a cord rubber is compressed or stretched, it absorbs the force and resists deformation. As a result, the elastic nature of the rubber returns to its original shape and size when pressure is released. This process results in improved cushioning and vibration-dampening properties.

Rubber cord works as a barrier against different external factors. These factors may include dust, moisture, and forces that can cause damage or impact performance. It also works against vibration and reduces noise. As a result, you will see the application of this product in many industries. The popular sectors are automotive, aerospace, construction, marine, electrical and medical. The manufacturing process for rubber cords typically involves several steps. It includes preparation of the raw materials, extrusion of the cord rubber, vulcanization, and finishing.

  • Applicazioni automobilistiche: Rubber cords are also prevalent in various automotive applications. Engine mounts, fuel tanks, and door seals are the most common examples of rubber cord applications.
  • Aerospace Applications: Aircraft windows, door seals, and fuel tanks require high-quality rubber cords.
  • Sporting Goods: Rubber cords are also prevalent in sporting goods such as tennis rackets and gym equipment. They absorb shock to reduce the impact of ball and racket collisions.

Types of Rubber Cord

A rubber cord may come in various types. Each of these types is designed to suit different applications and requirements. Rubber cords come in various shapes and sizes to suit multiple applications. Here are some of the most common types of rubber cords:

  • Solid rubber cord: These rubber cords are made from solid rubber and are available in various shapes and sizes. The solid cord is popular in sealing applications. It is prevalent in applications requiring flexible material to prevent water, dust, or air from entering. Automotive, aerospace, and construction are some of the most popular sectors of applications.
  • Sponge rubber cord: These rubber cords are made from sponge rubber, which is popular in cushioning applications. Since they are compressible, they can absorb impacts. As a result, it can reduce vibration in industrial machinery and equipment. Sponge rubber cords are popular in the HVAC, electrical, and automotive sectors.
  • Hollow rubber cord: These rubber cords usually have an open center from extruded rubber. They are also prevalent in sealing and cushioning applications. These rubber cords are often used as door seals and window seals.
  • Co-extruded rubber cord: These rubber cords are made from multiple layers of rubber materials. They are incredibly beneficial for applications where flexibility and hardness are the concerns. However, co-extruded rubber cords are often prevalent in automotive and aerospace applications.

Rubber Cord Materials

Rubber cords come from various types of rubber materials. Each type of material provides unique properties and capabilities. Here are some of the most popular rubber materials:

A. Natural Rubber

Natural rubber usually comes from the sap of the Hevea brasiliensis tree. It is a highly versatile polymer. It has excellent strength, flexibility, and elongation properties. As a result, it has become ideal for many applications. The most famous natural rubber cord application sectors are automotive, construction, and marine.

B. Synthetic Rubber

This type of cord rubber comes from an artificial compound. It mimics the properties of natural rubber. Synthetic rubber offers enhanced durability and resistance to harsh environmental conditions. However, some most popular synthetic rubber cords are:
