DEKUMA TPV Extrusion Line produces high quality hose for EVs


Recently, DEKUMA supplied a TPV Knitted Composite Hose Extrusion Line for a Chinese well-known automobile fluid pipeline manufacturer, and completed acceptance successfully.

With the development of electric vehicles (EVs), the advancement of automobile industry technology, and the enhancement of people’s awareness of environmental protection, electric vehicles are becoming more and more popular.

At present, the materials used in the manufacture of automotive fluid pipelines can be divided into three types, metal, rubber, and nylon plastic.

The electric cooling system of EVs is particularly critical, liquid cooling is currently the main way for EVs cooling. As an important part of EVs, coolant fluid pipelines need to meet multiple requirements such as hydrolysis resistance, high temperature resistance, and lightweight.

In recent years, Thermoplastic Vulcanizate (TPV) has the characteristics of both rubber and plastic, and its application in fluid pipelines of EVs has become more and more extensive.

DEKUMA launched TPV Knitted Composite Hose Extrusion Line for EVs, which adopts the combination of TPV (inner layer) + knitted layer (polyester, aramid) + TPV (coating layer), which can simultaneously provide three product structures production solution of TPV knitted composite hose, TPV double-layer composite hose and TPV single-layer hose.

In full use of TPV material light weight, simple process, easy connecting, shockproof characteristics, while using the intermediate fiber knitted reinforcement layer to increase the compressive strength of the hose, improve the safety factor.

TPV can better combine the material characteristics of plastic and rubber, and has alternative advantages in the application of cooling pipeline of EVs in the future.

DEKUMA TPV Knitted Composite Hose Extrusion Line, the inner TPV hose body is accurately extruded by the inner TPV extrusion system, through customized knitted coating fiber reinforced layer, and then through the infrared heating system to make the knitted layer and the inner and outer layer materials perfectly bonded, forming a complete TPV knitted composite hose.

The acceptance samples have been tested and approved by a number of testing institutions in China and Overseas, and the products fully meet the requirements of EVs fluid management.

After nearly three years of development, the application of new materials has gradually extended from “hard” power to “soft” power.

DEKUMA self-developed the TPV Knitted Composite Hose Extrusion Line, which has accelerated the application process of new materials and new fields, and solved the core production problem of “bottleneck” in the development of the auto parts industry.

DEKUMA TPV Knitted Composite Hose Extrusion Line not only realizes the breakthrough in the supply of new materials for EVs, but also further realizes the foresight development of China made equipment, forming a new generation of products and a new line of industry leadership status.

In future, with the increasing application cases of new materials to pipelines, through the continuous exploration of different structure performance, DEKUMA will bring a new boost to the development and iteration of EVs fluid pipeline!
