Distinction and Selection of High, Medium and Low Temperature of Hot Melting Glue on Enclosure of EVA Furniture

   According to the difference of using temperature, the hot melt gum on the sealing edge of furniture can be divided into three types: high temperature glue, medium temperature glue and low temperature glue. In order to meet more market demand, according to different production processes and costs, different heat melt rubber manufacturers have made different grades of high, medium and low temperature gum. How to choose the most suitable for your edge heat melt glue, which needs to understand the difference in their performance.
1, the difference between the same grade of high school low temperature glue:
Strength: High temperature rubber & amp; Gt; Moderate gum & amp; Gt; Low temperature glue;
Appearance hardness: high temperature rubber & amp; Gt; Moderate gum & amp; Gt; Low temperature glue;
Elasticity: low temperature gum elasticity is relatively poor, high temperature gum elasticity is good;
Different temperature of use;
Cold resistance: The cold resistance of high temperature gum is slightly better than that of low temperature gum.

2, the difference between different grades of high school low temperature glue:
Strength: The higher the grade, the better the strength;
Liquidity: High-grade liquidity will be slightly better;
There are differences in aging resistance and heat resistance;
Cold resistance: the difference is most obvious, the more fillers, the worse the cold resistance;
Solvent resistance: It is mainly for painting paint after sealing the wood skin. All hot melts are not solvent resistant. They only differ in the strength of solvent resistance. The higher the gum, the stronger the solvent resistance will be. If the same grade of gum, high temperature glue & amp; Gt; Moderate gum & amp; Gt; Low temperature glue.
At present, the scale of domestic hot melt rubber manufacturers is uneven, and each manufacturer has a very different position in the market of its own products. Due to the pressure of the current market competition, some manufacturers have chosen to reduce production costs in order to make the low-end sealing gum., coated rubber is the most dominant, The common features of this type of low-end gum are:
1. Low price;
2. There is no planning or management for each area and each market.
3. The performance of hot melt glue is unstable in all aspects, and customers complain more;
Therefore, comparing the performance of hot melt glue, we should try to use the same level of high, medium and low temperature glue comparison.
