Through previous understanding of resin tiles, we should all know that the long life of resin tiles is closely related not only to the underlying material but also to the engineering resin of the surface layer. In addition to UV protection and color fading prevention, the surface resin must also have fire prevention and anti-aging functions. There are two commonly used ones on the market now, one is ASA engineering resin, and the other is ABS engineering resin. The market price of ASA is much higher than that of ABS engineering resin. So, how big is the performance difference under such a similar appearance? Let’s take a look together.
1. Different fire resistance
Compared to ABS, ASA has a substantially improved fire resistance due to the replacement of butane rubber with acrylamide butane rubber without double bonds, which is about 10 times higher than ABS; its fire rating is B1, meeting the basic requirements of residential buildings.
2. Different exposure properties
ASA resin tiles exposed to sunlight for 9 to 15 months have no decrease in impact strength and elongation, and no change in color.
3.3. Different impact resistance
Due to the special structure and composition of ASA resin, ASA has better impact resistance, weather resistance and high temperature resistance than ABS. It is necessary to choose ASA as the surface coating resin tile, so as to ensure the service life of the resin tile and the overall appearance.
In summary, the main difference between ABS and ASA lies in their weather resistance and UV resistance. ASA’s weather resistance is more than 10 times that of ABS, which means that products made of ASA can remain unchanged in color and shape in outdoor and complex environments for a long time, while ABS will quickly yellow and become brittle under the same conditions, leading to scrap. Therefore, it is recommended that when choosing synthetic resin tiles, one must choose to use ASA as the surface coating resin tile, so as to ensure the service life and overall appearance of the resin tile.
