Xiamen LFT Nylon series Polyamide 66 Long Glass Fiber Reinforced Thermoplastic Resin

Polyamide, which is also known by the trade name, Nylon, has excellent heat resistant properties, especially when combined with additives and filler materials. In addition to this, Nylon is very resistant to abrasion. Xiamen LFT offers a wide range of temperature-resistant nylons with many different filler materials.

About PA66-LGF compounds

Nylon 6,6, also written as nylon 6-6, nylon 66, or nylon 6/6, is a more crystalline version of nylon 6. It is also referred to as polyamide 66 or PA 66. It has improved mechanical properties due to its more ordered molecular structure. Nylon 66 for machining has improved temperature resistance and lower rates of water absorption when compared to standard nylon 6. 

The advantages of nylon 6,6 are that the yield strength is higher than nylon 6 and nylon 610. It has high strength, toughness, rigidity, and low coefficient of friction in a wide temperature range. In addition, it is oil resistant and resistant to chemical reagents and solvents.

However, PA66 has strong hygroscopicity and poor dimensional stability, which limits its application. In order to obtain nylon 66 engineering material with higher strength, it should be modified by glass fiber reinforcement.

The mechanical properties of long glass fiber reinforced nylon 66 (LGFR-PA66) are obviously better than those of short glass fiber reinforced nylon 66 (SGFR-PA66), and the molding processing performance is also better. It can be molded by various molding methods such as injection molding and compression molding, and complex components can also be formed.

The production process of long glass fiber reinforced nylon 66 is different from that of short glass fiber reinforced nylon 66.

The short glass fiber reinforced nylon 66 particle is chopped under the friction and shearing of screw and barrel, and the short glass fiber reinforced nylon 66 particle is obtained with the length of glass fiber monofilament about 0.5mm. The length of some glass fiber monofilament in the final product is lower than the critical length of reinforcement, and the glass fiber is easy to be extracted from the nylon 66 matrix when the product is stressed. The strength of glass fiber is not fully utilized, and the mechanical properties of the product are not high.

Long glass fiber reinforced nylon 66 has better reinforcement effect and dimensional stability, and the rigidity, tensile, bending, impact resistance and fatigue resistance of the manufactured products are better, and the service life is longer.

About Xiamen LFT

Xiamen LFT Composite Plastic Co.,LTD was established in 2009, is a brand-name global suppliers of long fiber reinforced thermoplastic materials integrating product research & developmen （R&D）, production and sale marketing. Our LFT products have passed the ISO9001&16949 system certification and have obtained lots of national trademarks and patents, covering the fields of automotive, military parts and firearms, aerospace, new energy, medical equipment, power wind energy, sports equipment, etc.

LFT long fiber reinforced thermoplastic engineering materials,compared to ordinary short fiber reinforced thermoplastic materials (fiber length is less than 1-2 mm), the LFT process produces thermoplastic engineering material's fibers in lengths of 5-25 mm. The long fibers are impregnated with the resin through a special mold system to obtain long strips that are fully impregnated with the resin ,and then cut to the length as required.   The most used base resin is PP, by PA6, PA66, PPA,PA12,MXD6,PBT,TPU,PPS, ABS,PEEK, etc. Conventional fibers include glass fiber, carbon fiber. Depending on the end use, the finished products can be used for injection molding,extrusion, molding, etc., or directly used for plastic instead of steel and thermoset products.
