What exactly are the advantages of TPU in charging pile cables?
describe:
With the gradual deepening of the concept of green lightweight, new energy vehicles as the new darling of the automotive industry, its various components are subject to sustained external attention. Charging pile cable as an important carrier connecting the charging pile and new energy vehicles, need to withstand the pressure of high current transmission for a long time and the test of outdoor climate. In order to ensure the stability and safety of the charging cable, the choice of cable material is more demanding.

Overmolding Techniques & Adhesion Requirements
SILIKE Si-TPVs Overmolding can adhere to other materials through injection molding. suitable for insert molding and or multiple material molding. Multiple material molding is otherwise known as Multi-shot injection molding, Two-Shot Molding, or 2K molding.
SI-TPVs have excellent adhesion to a variety of thermoplastics, from polypropylene and polyethylene to all kinds of engineering plastics.
When selecting an Si-TPV for an over-molding application, the substrate type should be considered. Not all Si-TPVs will bond to all types of substrates.
For more information regarding specific over-molding Si-TPVs and their corresponding substrate materials, please feel contact us.
Application
Si-TPV Modified Soft Slip TPU in addition to the new energy automotive industry applications include charging pile cable raw materials, TPU cable modification additives, is the new energy industry can not miss the innovative solutions!
1. Cable environment requirements
Natural environment: charging car cables are exposed to the outdoors for a long time, and will encounter sunlight, humidity, freezing, etc., so the cable is required to have UV resistance and low temperature resistance. China has a wide range of regions and needs to meet the requirements of different regional conditions.
Man-made environment: Dragging, twisting, bending, stretching, etc. will inevitably occur during the charging process, which is very likely to cause mechanical damage, so it is necessary to reduce the bending and flexing stress and increase the flexibility of the cable. In the process of use may also cause corrosion of acid and alkali liquids, so it needs to have excellent chemical resistance.
2. Functional requirements
Electric vehicle charging in addition to charging also need to communicate, if necessary, automatic control.
3.Safety requirements
Electric vehicle charging process time is short, current intensity, high frequency of use, to ensure good insulation at the same time also requires materials with a certain degree of high temperature resistance, aging resistance, and in the combustion of halogen-free flame retardant and low smoke density.
Si-TPV Modified soft slip TPU granules are a Dirt-Resistant thermoplastic vulcanizate Elastomers Innovations/ TPU with Improved Frictional Properties/ Matt effect surface TPU. used in charging pile cable, can be used as raw materials, can also be used as Reduce TPU hardness Modifier for TPU effectively solve the traditional wire in the quality of soft as well as other properties of the technical difficulties between the balance, effectively improve the surface of the TPU. Finish in Non-Tacky Elastomeric Materials.

In the new energy vehicle potential continues to release, the charging pile field also needs more green low-carbon overall material solutions. Si-TPV Modified soft slip TPU granules, help people's green travel. ★Flexibility, full pressure resistance With good strength, abrasion resistance, scratch resistance, delicate matte effect and other properties, effectively ensure that the charging cable does not crack after dragging on the ground friction, bending, stepping on the ground, or even crushing and other abnormal conditions, reduce wear and tear, extend the service life and provide excellent visual effects.
-
★Water and oil resistant, dirt-resistant and easy to clean Under the water, oil, dirt and aging resistance test, the charging pile cable TPU material still has a high retention rate of the performance, effectively ensure that the charging cable in the face of water immersion, oil and other abnormalities will not appear after the performance of abnormalities, so that the charging pile of the sense of security "full of", and easy to clean. ★Ultra-strong standby, dissolve wet temperature anxiety In the changing temperature and humidity, Si-TPV Modified soft slip TPU granules with excellent aging resistance, so that the surface of the cable protection sleeve without any cracking or failure and high strength retention, in the outdoor exposure, rain and snow and other environmental tests, giving the charging cable longer service life.
