Product Name:
Plastic Supporting Core With Polypropylene Reinforced For Telecom Duct Installation
Product Description:
Plastic Supporting Core
Plastic supporting core is a spiral-structured supporting component specially designed to support and expand various rubber products such as rubber tubes, rubber sleeves, cold-shrink tubes and other rubber fittings. As a key auxiliary part, plastic supporting core provides stable and lasting expansion force to keep rubber parts in an open and expanded state, which is convenient for installation, transportation and later application in power and telecom projects. Made of high-quality PP or PE raw materials, this plastic supporting core features high structural strength, good toughness and stable physical properties, ensuring long-term use without easy breakage or deformation. The whole plastic supporting core is processed by mature spiral forming technology, with uniform stress distribution and excellent matching performance with rubber parts. In addition to being used as an internal support for rubber components, plastic supporting core can also be machined and assembled into handles for hardware tools, bicycle grips, hand-held equipment and other daily and industrial products, realizing multi-scenario application.
Plastic Strip
Plastic strip is the special raw profile for manufacturing plastic supporting core. Made of PP or PE material, it is the basic semi-finished product for forming spiral plastic supporting core of different diameters. Through automatic spiraling equipment, the plastic strip can be processed into standard or customized plastic supporting core efficiently and stably. It is compatible with auto-buckled and welding processes, which can realize continuous automatic production, with high welding joint strength and not easy to deform after forming, laying a solid foundation for the stable quality of it.
Product Application:
1. Plastic supporting core is mainly used as an inner supporting and expanding part for cold-shrink rubber tubes, cold-shrink cable terminals and cold-shrink joints in the power industry, providing stable support to ensure the normal installation and use of power cable accessories. It can effectively prevent the rubber parts from shrinking in advance during transportation and construction, ensuring the smooth progress of power engineering construction.
2. In the telecom industry, plastic supporting core is widely applied in optical cable accessories, communication cable joints and communication cold-shrink products, maintaining the expanded shape of rubber parts to meet the construction requirements of communication lines. It is suitable for various harsh construction environments such as underground, outdoor and high-altitude, and can maintain stable supporting performance for a long time.
3. Plastic supporting core can be used as the inner support structure for various tool handles, including maintenance tools, electric tools and manual tools. It can enhance the structural strength of the handle, avoid deformation and breakage during use, and improve the comfort and service life of the handle.
4. Plastic supporting core is also suitable for making bicycle grips, scooter handles and other sports equipment handles. It has the advantages of light weight, good toughness and stable supporting effect, which can effectively improve the use experience of the equipment and ensure the safety of users during use.
5. In industrial assembly and mechanical supporting fields, it can be used as a general spiral supporting part for rubber hoses, protective sleeves and other flexible parts. With good corrosion resistance and anti-bioerosion performance, it can adapt to various harsh industrial environments and has a long service life, reducing the frequency of replacement and maintenance.
