SUNBOW transparent heat shrinkable tube is made of radiation cross-linked environmentally friendly polyolefin heat shrinkable material, which is environmentally friendly. Through accelerated aging experiments, it has been proved that its service life is more than 5 years, its tensile strength is greater than 7.3Mpa, and its performance decay rate is less than 3% after aging for 168H. After comparing several transparent heat-shrinkable tube manufacturers, the customer confirmed that SUNBOW transparent heat-shrinkable tube has the best performance and the longest service life, and is a real insulating sleeve supplier.

At present, most transparent heat-shrinkable tubes on the market use polyolefin as the base material, and it is not difficult to find out that although polyolefin has a long history, it is widely used in general electronic products, and the requirements for service life are generally average. That is about 3 years, which is far from the service life of more than 5 years required by some customers. ( PVC tubing)

This problem has been noticed by customers for a long time, but because the transparent heat shrinkable tube is a relatively special product, there is no professional verification standard matching it in the industry, and customers can only try it, and there is no way to verify it in advance.

When SUNBOW decided to develop transparent heat shrinkable tubes a few years ago, it discovered this defect in the industry. When developing transparent heat-shrinkable tubes, we first analyzed various indicators, and at the same time developed a set of accelerated aging life prediction algorithms, which were certified. Through more than 5 years of research and development verification and more than 1,000 performance tests, the service life of SUNBOW transparent heat shrinkable tube exceeds 5 years, which is not only in the domestic market, but also in the world. A conservative estimate is at least 2-3 years ahead of its peers. ( silicone tubing)

Some time ago, a wiring harness customer found SUNBOW through their customers, because SUNBOW is used to communicating with customers on technology, so they introduced SUNBOW to their downstream suppliers, hoping to use SUNBOW's transparent heat shrinkable tubes. This customer's evaluation of SUNBOW is very high, they say that if the industry is professional, it is SUNBOW. The reason why customers say this is not only that the quality of SUNBOW products is good, but more importantly, in addition to products, we can also provide various performance tests and verifications such as accelerated aging life prediction, which are beyond the capabilities of other peers.

SUNBOW transparent heat shrinkable tube has the following core advantages:

1) It has 8 invention patents, and similar products cannot be found at home and abroad at present.

2) The service life of more than 5 years is 2 times longer than that of the brother company.

3) SUNBOW transparent heat shrinkable tube aging test 168H, the performance attenuation is less than 3%.

4) Exclusive accelerated aging life prediction, which cannot be done by friends.

5) The transparent heat-shrinkable tube is flame-retardant, and currently only SUNBOW is doing it.

At present, SUNBOW's transparent heat-shrinkable tubes have been sent to more than 500 Fortune 500 companies. Due to confidentiality agreements, it is inconvenient to disclose customer information. Maybe customers are helping SUNBOW to promote it, or maybe they know from the news on SUNBOW's official website that there is no need to worry about the quality of SUNBOW transparent heat shrinkable tubes, and it is worth a small test.
