The quality of Silicone heat blanket are the main factors determined the length of its service life, but how to find and identify a good silicone heat blanket isn’t easy, in the following content will talk about how to identify a good silicone heat blanket from two aspects.
1. Product temperature performance
The common silicone heat blanket in the market generally uses silica gel heating line, PVC electric hotline and teflon plus hotline. In terms of performance, teflon plus hotline is certainly the best choice, but its high price makes its cost greatly increased and appears to be cost-effective. PVC is a common heating line in the current production, but it has a great disadvantage is when the heat blanket heating to a high temperature will get easy to melt, and some manufacturers in the current market choose to recycle materials for reproduction, which virtually reduces the service life and safety of the product.
2. The bending performance
In terms of bending performance, the quality of heating wire is the key to the service life of silicone heat blanket, the better the heating wire represents the higher safety factor and longer service life. At present, the common heating wire on the market has nickel chromium alloy, copper nickel alloy. According to UL specifications, only wires with more than 25000 bending tests meet the production standard, but many manufacturers are prone to break after 7000 tests.
