What are the advantages and disadvantages of ABS plastic

ABS plastic, on the basis of the original pure plastic, adding glass fiber and other additives to improve the characteristics of FRP. Glass fiber reinforced materials can be made into a variety of composite functional materials with special properties and a wide range of uses. This greatly increases the range of applications of plastic materials.

Generally speaking, most ABS plastics are mostly used in automobiles, engineering parts, electrical components, etc. Common FRP ABS PP PA6 PA66 PC/ABS POM PBT and other engineering plastics.

The main advantages of ABS plastic, glass fiber reinforced plastic are:

1. After glass fiber reinforced, glass fiber is a kind of high temperature resistant material. Therefore, the heat resistance temperature of reinforced plastics is much higher than before without glass fiber.

2. After the glass fiber is reinforced, the addition of the glass fiber limits the mutual movement of the plastic polymer chain, so the shrinkage rate of the reinforced plastic decreases a lot, and the rigidity is greatly improved;

3. After the glass fiber is reinforced, the reinforced plastic will not crack under force, and the impact resistance of the plastic will be improved a lot;

4. After glass fiber is reinforced, glass fiber is a high-strength material, which greatly improves the strength of plastics, such as tensile strength, compressive strength, and bending strength;

5. After glass fiber is reinforced, due to the addition of glass fiber and other additives, the combustion performance of reinforced plastics decreases a lot, and most materials cannot be ignited, so it is a flame retardant material.

The main disadvantages of glass fiber reinforced ABS plastic are:

1. After the glass fiber is reinforced, because the glass fiber is added, it is transparent before adding the glass fiber and will become opaque;

2. After glass fiber reinforced, the toughness of all plastics decreases, but the brittleness increases;

3. After glass fiber reinforcement, due to the addition of glass fiber, the melt viscosity of all materials increases, the fluidity becomes worse, and the injection pressure is much higher than that without glass fiber.

4. After glass fiber reinforcement, due to the addition of glass fiber, the fluidity is poor. In normal injection, the injection temperature of all reinforced plastics is 10 ℃-30 ℃ higher than that without glass fiber.

5. After glass fiber reinforcement, due to the addition of glass fiber and additives, the moisture absorption performance of reinforced plastics is greatly enhanced. Pure plastic that does not absorb water will also absorb water. So in the injection molding process to dry.

After the glass fiber is reinforced, the glass fiber will enter the surface of the plastic product during the injection molding process, making the surface of the product rough and spotty. In order to obtain a higher surface quality, it is best to use a mold temperature machine to heat the mold during injection to make the plastic polymer enter the surface of the product, but it cannot reach the appearance quality of pure plastic.

7. After glass fiber reinforced, glass fiber is a material with high hardness. After the additive volatilizes at high temperature, it is a very corrosive gas, which will cause great wear and corrosion to the screw and injection mold of the injection molding machine. Therefore, when using such materials to produce molds and injection molding machines, attention should be paid to the surface anti-corrosion treatment and surface hardness treatment of the equipment.
