Glass Fiber Reinforced ABS Plastic Granule

ABS is a thermoplastic with good comprehensive performance, but its strength, hardness, dimensional stability and thermal deformation temperature can not meet the requirements of some engineering parts. Glass fiber reinforced ABS not only maintains the original mechanical properties, thermal stability and machinability of ABS, but also can effectively improve its tensile strength, elastic modulus, thermal deformation temperature and dimensional stability, so as to expand the application field of ABS.

Glass fiber reinforced ABS composite material is a new thermoplastic which is made by adding the glass fiber after surface treatment into the twin-screw extruder with ABS resin as the main body. It not only maintains the mechanical properties, electrical properties, thermal properties and machining properties of the original material, but also has the following advantages: a higher elastic modulus, the material stiffness has been greatly improved; The thermal deformation temperature is increased significantly, and the range of application temperature and application field are expanded. The linear expansion coefficient is significantly reduced, the molding shrinkage rate is significantly reduced, and the dimensional stability of products is enhanced.

Glass fiber reinforced ABS and other reinforcing materials, although its impact strength is significantly reduced than pure ABS, its rigidity, heat resistance and dimensional stability are significantly improved, its bending strength and tensile strength are increased by 2-3 times, the thermal deformation temperature is increased by 10-15℃ compared with pure ABS, and the molding shrinkage rate is reduced by 1/4 to 1/2. Weather resistance is also improved compared with pure ABS, providing the possibility of outdoor use.

For glass fiber reinforced ABS, the higher the mixing temperature is, the more evenly the glass fiber is dispersed in the ABS matrix. In this way, the material defects that may be caused by the non-uniform inorganic filler are reduced, and the overall uniformity of the blended material is ensured, so that it has better mechanical properties.
