Compared with PC, PC/ABS alloy has the following advantages:
1、 Under widespread usage conditions, it will only exhibit plastic failure, reduce residual stress, and improve stress cracking resistance. At room temperature, its impact strength is 3-4 times that of PC.
2、 Excellent boiling water resistance, after treatment at 100 ℃ for 240 hours, the tensile strength and bending strength remain almost unchanged, and the tensile strength is more than three times that of PC treated under the same conditions.
3、 Good aging resistance, after treatment at 120 ℃ and 140 hours, its impact strength is still more than twice that of PC.
4、 Excellent weather resistance, exposed outdoors for 2 years, with almost no change in tensile and bending strength, and an impact strength more than 4 times that of PC.
5、 The melt viscosity is reduced by 1/3, so the molding temperature can be lower, molding is easier, residual stress is reduced, and the product color is also better. In addition, the melt viscosity of the blend decreases significantly with increasing molding pressure, which also improves the formability.
The characteristics of PA nylon
The mechanical properties of PA, such as tensile and compressive strength, vary with temperature and moisture absorption. Therefore, water is relatively the plasticizer of PA. After adding fiberglass, its tensile and compressive strength can be increased by about 2 times, and its temperature resistance can also be correspondingly improved. PA itself has a very high wear resistance, so it can operate continuously without lubrication. If you want to obtain a special lubrication effect, sulfides can be added to PA. Suitable plastic products: various gears, turbines, racks, cams, bearings, propellers, transmission belts. Other: The shrinkage rate of 1-2% needs to pay attention to the dimensional changes in moisture absorption after molding. Water absorption rate: can absorb 8% when saturated with 100% relative moisture absorption. Suitable wall thickness: 2-3.5mm
It has good tensile strength, impact resistance, rigidity, wear resistance, chemical resistance, surface hardness and other properties. It has a high transmittance, similar to optical glass, and a processing temperature of 300-315 ℃. During molding and processing, it is necessary to strictly control the temperature of the barrel. If the melt temperature is too high, it will cause discoloration of the product due to degradation, and if the temperature is too low, it will affect the transparency of the product due to poor plasticization. Try to keep the mold temperature as low as possible, as high mold temperatures can reduce the transparency of the product due to crystallization.
The main applications of nylon
With the acceleration of miniaturization of automobiles, high-performance electronic and electrical equipment, and lightweight mechanical equipment, the demand for nylon will be higher and greater. Especially as a structural material, nylon has high requirements for its strength, heat resistance, and cold resistance. The inherent drawbacks of nylon are also an important factor limiting its application, especially for the two major varieties PA6 and PA66, which have a strong price advantage compared to PA46, PAl2 and other varieties, although some performance cannot meet the requirements of related industry development. Therefore, it is necessary to target a certain application field and expand its application scope by modifying and improving certain performance. Due to the strong polarity of PA, it has strong moisture absorption and poor dimensional stability, but it can be improved through modification.
