Xiamen LFT-G Polyamide 66 nylon materials reinforced plastic high mechanical properties customized color and length

Polyamide 66

Nylon 66 (PA66) has excellent mechanical properties, processing performance and corrosion resistance, after flame retardant modification of PA66 can be widely used in automotive, electronics, machinery and other fields. With the wide application of nylon in different fields, the requirements for its performance have been taken to the next level.

However, PA66 has high crystallinity and fast crystallization speed, and is prone to warpage defects during injection molding process. Especially for glass fiber reinforced nylon 66, due to the anisotropic arrangement of glass fibers inside the material, it is easy to cause different shrinkage rates in all directions, which further aggravates the warping deformation.

Long glass fiber reinforced composites

Glass fiber is an excellent performance of inorganic non-metallic materials, mostly used for reinforcing plastics. Mainly silica as raw material, add specific metal oxides mineral raw materials melted at high temperature, molten glass liquid flow through the leakage nozzle out of the role of high-speed pulling gravitational force is drawn and rapid cooling and curing into a very fine continuous fibers, the diameter of a few microns to more than twenty microns.

Glass fiber is divided into short glass fiber, long glass fiber according to the shape.

Short glass fiber: length less than 6mm, cross-section is round, in the material distribution disorder, anisotropy.
Long glass fiber: length between 6-25mm, orderly distribution in the material, isotropic.

Short Glass Fiber Nylon: Processability, rigidity and strength are improved, and floatation is less likely to occur during injection molding compared to long glass fiber nylon.

Long glass fiber reinforced nylon: less anisotropic shrinkage compared to short glass fiber, reducing the effect of warpage. The rigidity, abrasion resistance, aging resistance, and heat resistance are stronger than those of short glass fiber reinforced nylon.
