RU Through the past several periods of the understanding of the resin tile, we should understand that the long life of the resin tile is not only related to the bottom material, but also closely related to the engineering resin of the surface layer. Face layer resin in addition to have anti-ultraviolet light, anti-fading, but also must have fire prevention, anti-aging function. Now there are two most commonly used in the market, one is ASA engineering resin, the other is ABS engineering resin, the market price of ASA is much higher than ABS engineering resin, so how different can the performance be under the very similar appearance? Let’s take a look together:
1,different fire resistance
Compared with ABS, due to the introduction of acrylic rubber without double bonds, the fire resistance is about 10 times higher than ABS; the fire rating is B1, meeting the basic residential requirements.
2,the sun exposure sex is different
The ASA resin tile was exposed to the sun for 9 to 15 months, and the impact strength and elongation did not decrease, and the color did not change.
3,Different impact properties
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 use ASA as the surface coating of the resin tile, so as to ensure the service life and overall appearance of the resin tile.
Overall, the main difference between ABS and ASA lies in climate resistance and ultraviolet resistance. The climate resistance of ASA is more than 10 times that of ABS. Generally speaking, the products made by ASA can not change color and deformation in outdoor and various complex environment for a long time, while ABS will soon turn yellow and brittle under the same conditions, leading to scrap. Therefore, it is suggested that when choosing synthetic resin tile, we must choose to use ASA as the surface coating of the resin tile, so as to ensure the service life of the resin and the overall appearance of the tile.
