The addition of glass fibers to the polymer usually makes its surface rougher, which can lead to a reduction in gloss. The specific degree of impact depends on the proportion, length and shape of the glass fiber added, as well as processing conditions and other factors.
Glass fiber is relatively rough, and incompatible with plastic, added to the plastic material, resulting in a less smooth surface, which affects the appearance of the material. In some components, this effect may be acceptable, especially where increased material strength and rigidity are required, as glass fibers typically provide these mechanical improvements. However, if it is a surface appearance part, and the mold is still smooth, it will have a greater impact on the appearance.
If you have special requirements for gloss or beauty, you need to replace the material, such as PP+ filler material, or ABS material, to improve the beauty. If you are not sure how to choose a plastic material, you can email Xiamen LFT and have a professional plastics engineer recommend it to you.
