1. ASA has good mechanical and physical properties. ASA and ABS have similar structures and are composed of acrylonitrile and butadiene rubber. It retains the excellent mechanical and physical properties of ABS 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 in the sunlight with greater energy intensity, which will cause the degradation of the aging resistance of the polymer. And ASA is replaced by acrylic rubber that does not contain unsaturated double bonds...
As the largest and most important engineering plastic variety, nylon has strong vitality, mainly because it has been modified to achieve high performance, followed by automotive, electrical, communications, electronics, machinery and other industries to meet high performance requirements. Product. The development of related industries has become more and more intense, which has promoted the development of high-performance engineering plastics. The future development trend of modified nylon is as follows. 1 The market's demand for high-strength and high-rigidity nylon is increasing...
ASA is an opaque yellow amorphous polymer, odorless and non-toxic. Its flame retardancy can reach UL94HB level, burns slowly, and emits the smell of benzene and rubber. The relative density of ASA is 1.05~1.09, and the notched impact strength It is 480~580J/m, the tensile strength is 38~48MPa, the heat distortion temperature is 85~105°C under 1.86MPa load, it can be used at -20~75°C, and it has better high temperature resistance. .......
1. The fire resistance is different. Compared with ABS, ASA has introduced a double bond-free acrylate rubber instead of butadiene rubber, so the fire resistance has essentially changed, which is about 10 times higher than that of ABS. The fire resistance is B1. Meet the basic residential requirements. 2. Different ASA resin tiles exposed to sunlight for 9 to 15 months, the impact strength and elongation did not decrease, and the color did not change...
Reasons for the shiny surface of ASA plastic products 1. The temperature is high. Each crystalline plastic has a fixed melting point. If the temperature exceeds the melting point, it will burn. 2. There are impurities in the material, such as PA66+GF30. But. The material contains those low molecular weight impurities. Your injection temperature is set within a reasonable range of 280-290, but the impurities inside cannot withstand the high temperature of 280-290...
