The main component of synthetic resin tile is synthetic resin, so what is synthetic resin, the following is a brief introduction:
Synthetic Resin - is a synthetic class of high molecular weight polymers. ASTM D883-65T defines a synthetic resin as a solid, semi-solid, or pseudo (quasi) solid organic substance of unqualified molecular weight, often of high molecular weight, which has a tendency to flow under stress, and which often has a range of softening or melting and which appears as a shell when ruptured.
In practice it is often used synonymously with polymers and even plastics on the one hand, and in particular to refer to basic materials produced by polymerization of monomers without any additives or with only a very small amount of additives. In addition, it is also sometimes used to represent uncured, fluid thermosetting polymer materials.
The world's three major synthetic materials include synthetic resins, synthetic rubber and synthetic fibers. Synthetic resins are the synthetic materials with high production and consumption.
Synthetic resin tile surface material is the key, the selection of surface materials directly affect the service life of the resin tile, in most cases the selection of super weather-resistant material ASA, co-extruded through the surface of the molding. The weather resistance of the product directly leads to the service life of the synthetic resin tile. What is ASA? Here is a brief introduction.
ASA plastic raw materials - is acrylate rubber body with acrylonitrile, styrene graft copolymer. Molding temperature is 170-230 ℃.
Benefits of ASA -
1、ASA has good mechanical and physical properties
ASA is structurally similar to ABS, consisting of acrylonitrile and butadiene rubber, and it retains the mechanical and physical properties that ABS has as an engineering plastic.
2、ASA has strong weather resistance
If the polymer contains double bonds, the double bonds are easily opened by the ultraviolet rays of the sunlight with higher energy intensity, which causes the aging resistance of the polymer to decline. ASA replaces the butadiene rubber containing unsaturated double bonds in ABS with acrylic rubber containing no unsaturated double bonds, and therefore not only resists degradation, aging, and fading caused by ultraviolet rays, but also provides a strong guarantee against decomposition or discoloration caused by high temperatures during oxidative processing in the atmosphere. The decomposition or discoloration caused by high temperature during oxidation process has been strongly guaranteed, which greatly improves the anti-aging and weather-resistant performance of the material. According to the test results, the anti-aging performance of ASA is more than 10 times that of ABS (some cheap resin tiles are made of ABS instead of ASA, so the price is cheap, but the quality, as you can imagine).
3, ASA has better high temperature resistance performance
4, ASA is an anti-static material, can make the surface less dust accumulation
ASA Application Areas
Automotive field: ASA will not turn gray (due to many microscopic cracks and cavitation on the surface caused by wind erosion or water flow) like specially treated aging-resistant ABS after sustained wind erosion for a long period of time.Typical applications of ASA are exterior mirrors, radiator grills, tailgates, lampshades, and other exterior parts subjected to harsh conditions such as sunlight and rain, and strong wind blowing. More gradually, it has been extended to motorcycle panels, camping cars, small boat hulls, surfboards and other fields.
Horticulture: ASA has proven to be particularly suitable for horticultural irrigation equipment and lawn cutter housings, among others.
Electrical and electronic field: It is preferred to be used in the casing of durable equipment, such as: sewing machine, telephone, kitchen equipment, satellite antenna and other all-weather casing.
Construction field: ASA/PVC blends are used for roof siding and window materials, which have been practically applied abroad for more than 10 years.
In the United States, ASA has been widely used in bathroom and sanitary products, hot and cold water exchangers, etc., due to its good surface quality and long-lasting stable color, which indicates that ASA also has corrosion resistance to cleaning agents and disinfectants.
