1. Let the molecular model of the polymer be formed into a three-dimensional structure to form a mesh, thereby inhibiting molecular motion.

 

    2. Add difficult to move aromatic rings and alicyclic structures inside the molecular structure;

 

    3. Adding polar groups inside the polymer, so as to rely on the binding force like hydrogen and oxygen chains to inhibit the molecular structure;

 

    4. The crystal structure is introduced into the polymer structure for heat-resistance modification and a heat-resistant modifier is used.

 

    ABS plastic material properties

 

    1, conventional performance

 

    Plastic ABS is non-toxic and odorless, and its appearance is ivory translucent, or transparent particles or powder. Density is 1.05~1.18g/cm3, shrinkage is 0.4%~0.9%, elastic modulus is 2Gpa, Poisson's ratio is 0.394, hygroscopicity is <1%, melting temperature is 217~237°C, thermal decomposition temperature is> 250 °C.

 

    2, mechanical properties

    Plastic ABS has excellent mechanical properties, its excellent impact strength, can be used at very low temperatures; plastic ABS excellent wear resistance, dimensional stability, and oil resistance, can be used for medium load and low speed Bearing. The creep resistance of ABS is larger than that of PSF and PC, but smaller than that of PA and POM.

 

    3, thermal performance

    The heat distortion temperature of plastic ABS is 93~118°C, and the product can be increased by about 10°C after being annealed. ABS can still exhibit certain toughness at -40°C, and can be used within the temperature range of -40°C to 100°C.

 

    4, electrical performance

    Plastic ABS has good electrical insulation and is almost unaffected by temperature, humidity, and frequency and can be used in most environments.

 

    5, environmental performance

 

    Plastic ABS is not affected by water, inorganic salts, alkalis, and various acids, but it is soluble in ketones, aldehydes, and chlorinated hydrocarbons. It is susceptible to stress cracking when attacked by glacial acetic acid, vegetable oils, and the like. ABS has poor weatherability and is easily degraded under the action of ultraviolet light; after half a year outdoors, the impact strength is reduced by half.
