Most of the domestic manufacturers know that EVA heat shrinkable tubing can't be made of ultra-thin wall thickness. Shunbo is one of the few manufacturers in China that has the technology to make ultra-thin wall thickness EVA heat shrinkable tubing, and it is also the supplier that can replace the heat shrinkable tubing of international famous brands. Who said EVA heat shrink tubing can't be made ultra-thin wall thickness? That was before you met Sunbow.
EVA heat shrinkable tube wall thickness is very difficult to do ultra-thin, most manufacturers do not have the technical support, has not been able to do this. Can do ultra-thin wall thickness of heat shrinkable tube, the market is only PVC material or PET material, but used in battery packs, some countries are banned PVC material or PET material, most of the shrinkable tube manufacturers and battery pack manufacturers inside the heart of the anxiety, but also can only do nothing about it.
However, Shun Bo strong R & D team, from 2010, focusing on research and development of EVA material, ultra-thin heat shrinkable tube, only less than a year, to stabilise the quantity of product quality. Now has been supplied in bulk to many well-known battery pack manufacturers, EVA material ultra-thin heat shrink tubes, customers only choose Sunbow, other suppliers are no longer considered within the scope.
In mid-April this year, the United States, a battery pack manufacturing enterprises to find Shun Bo, consulting EVA heat shrinkable tube, the requirements of the shrinkage of the wall thickness of 0.1mm to 0.2mm, see the wall thickness of such a thin, recommended PVC heat shrinkable tubing, but the customer feedback on their countries prohibit the use of PVC heat shrinkable tubing in battery packs, previously also took the silicone material and PET material, but the performance of the silicone material does not meet the requirements, PET material at a temperature of 65 degrees Celsius in the heat shrinkable tube, but also the performance of the silicone material does not meet the requirements, and the performance of the silicone material does not meet the requirements. PET material in the temperature of 65 degrees environment will be brittle, also can not meet their requirements.
Understand that the EVA material heat shrinkable tube can meet their performance, before the customer took samples from many manufacturers to test, but the wall thickness is relatively single, no manufacturer can meet their requirements, to achieve ultra-thin wall thickness EVA heat shrinkable tube. To the customer recommended our ultra-thin EVA heat shrinkable tube SBD-SWHF, with micrometers to measure the wall thickness and take photos sent to the customer for reference, the customer can immediately take a sample test.
The next day the customer received the sample, feedback is very satisfied, measured the wall thickness, fully meet the customer's requirements. Next is the other performance test verification which lasted for a week, the battery pack focuses on acid and alkali resistance, which is expected, Shun Bo's ultra-thin EVA heat shrinkable tube meets their needs in all aspects. Ultra-thin wall thickness EVA heat shrinkable tube, the requirements of how thin the wall thickness does not need to worry about, the customer is very satisfied, immediately placed an order for 50,000 metres, the first has been formally mass production.
Sunbow ultra-thin EVA heat shrinkable tube has the following advantages:
(1) Insulation voltage up to 600V, breakdown voltage of 2500V within 1 minute will never break.
(2) Comply with UL 224 flame retardant certification, never fake, there is a third-party authority to test and verify the report UL E360625 certification.
3) Developed and produced ultra-thin wall thickness that most of the counterparts can't do. Halogen-free, low smoke, non-toxic, thin-walled, fast shrinkage.
Ultra-thin wall thickness EVA material heat shrinkable tubing, customers only choose Sunbow, other suppliers are no longer under consideration.
