Product Name:

Cold Shrink Plastic Supporting Core For Rubber Tube Expansion, Tool Handle & Bicycle Grip

Description:

The Cold Shrink Plastic Supporting Core is a high-performance internal support component engineered specifically for cold shrink installation applications. This Plastic Supporting Core serves as a temporary structural support that maintains rubber tubes, tool handles, and bicycle grips in an expanded state during installation. After the outer material is properly positioned, the Plastic Supporting Core is easily removed, allowing the rubber to contract tightly around the target object at room temperature without any heat application. The Cold Shrink Plastic Supporting Core is widely recognized for its reliability, ease of use, and superior performance across multiple industries including power, telecommunications, tool manufacturing, and bicycle manufacturing.

Product Application:

The Cold Shrink Plastic Supporting Core is designed to meet the demanding requirements of various industries:

• Power Industry – The Plastic Supporting Core is used for rubber tube expansion support in cable joints, terminations, and insulation protection applications.

• Telecom Industry – This Plastic Supporting Core provides internal support for cold shrink tubing used in antenna sealing, cable splices, and fiber optic protection.

• Bicycle Industry – This it functions as an internal support core for bicycle grips, ensuring stability and comfort during use.

• Other Industries – The Plastic Supporting Core can be applied in general industrial applications requiring internal support for rubber or plastic hoses.

FAQ

Q1: What is a Cold Shrink Plastic Supporting Core?
A: It is a temporary internal support core used in cold shrink installations. The Plastic Supporting Core holds rubber tubes or handles in an expanded state during installation. After positioning, the Plastic Supporting Core is removed, allowing the rubber to shrink tightly around the cable, tool handle, or bicycle handlebar without heat.

Q2: How is this product different from heat shrink products?
A: Unlike heat shrink products that require a heat source, the Cold Shrink Plastic Supporting Core enables installation at room temperature. This allows for safe, tool-free installation in environments where heat is not available or not recommended, such as explosive areas or outdoor settings.

Q3: What industries commonly use this Plastic Supporting Core?
A: This Plastic Supporting Core is widely used in the power industry, telecommunications industry, tool manufacturing, and bicycle manufacturing for applications such as cable joint protection, antenna sealing, ergonomic tool handles, and bicycle grips.

Q4: Can the size of the Plastic Supporting Core be customized?
A: Yes, we offer customization of the Plastic Supporting Core in terms of diameter, length, and wall thickness to meet specific application needs. Please contact us with your specifications.

Q5: Is this Plastic Supporting Core resistant to harsh environments?
A: Yes. The Plastic Supporting Core offers excellent corrosion resistance and resistance to biological erosion, making it suitable for outdoor, underground, and high-humidity environments.
