LFT-G® LGF40 Nylon 66 Polymer

LFT-G^® LGF40 Nylon 66 Polymer

What Is LGF40 PA66?

LFT-G^® LGF40 PA66 is a thermoplastic composite material that is based on polyamide 66 (PA66/Nylon 66) and contains 40% long glass fibers as the reinforcing phase.

Engineering Challenges

When ordinary reinforcing materials fail to meet the structural requirements,

engineering material selection often does not merely aim for higher individual strength, but also needs to consider the component stiffness, continuous load, installation accuracy and long-term performance.

Insufficient structural stiffness
Under continuous load or complex stress conditions, components may deform, affecting assembly and performance.

Size control of complex structures
Reinforcing ribs, bolts and multi-installation point structures impose higher requirements on the material's stiffness, flow and forming process.

Balancing lightweight and load-bearing
While controlling the weight of the components, mechanical strength, assembly and actual working conditions still need to be met.

Why Choose LGF40 PA66?

Long glass fiber reinforced structure

Compared with the common short glass fiber reinforced system, long glass fiber materials, under appropriate design and molding conditions, have better potential for impact resistance and load-bearing performance.

01

Higher structural stiffness potential

Suitable for injection molded components with high requirements for stiffness, deformation control, and structural support.

02

Structural integration design

Can be designed in combination with reinforcing ribs, support positions, and installation structures, helping to reduce unnecessary component combinations.

03

Metal substitution assessment

For components that meet strength, temperature resistance, fatigue, and safety requirements, it is possible to assess the substitution of some metal structures with engineering plastics.

LGF40 PA66: Appliation Ranges

 

Automobiles and transportation

Structural supports, installation supports, load-bearing connecting components.

Electrical and electronic equipment

Terminal block supports, equipment installation structure, load-bearing electrical enclosure.

Power tools and mechanical equipment

Motor support frame, peripheral structure of the gearbox, mechanical bearing housing.

Processing & Design

Material properties need to be coordinated with the molding process.
The final performance of long glass fiber materials is not only determined by the resin formula, but also affected by the mold structure, gate position, flow path, and molding parameters.

1. Mold and gate design: Minimize unnecessary flow turns and fiber damage as much as possible.
2. Molding parameter control: Optimize the barrel temperature, mold temperature, and injection conditions according to the recommendations of the material supplier.
3. Structural design optimization: Pay attention to wall thickness variations, reinforcing ribs, screws, and local stress concentration.
4. PA66 moisture management: Dry, store, and process before molding according to the material technical data.
5. Component verification: Evaluate dimensions, mechanical properties, heat resistance, and durability based on actual operating conditions.

FAQ

 

 

01.What is the difference between LGF40 PA66 and short glass fiber PA66?

Long glass fiber and short glass fiber materials differ in fiber length, fiber retention after molding, and reinforcement mechanisms. The long glass fiber solution is particularly suitable for evaluating components with high requirements for impact resistance, load-bearing capacity, and structural reliability.

02.Is LGF40 PA66 suitable for replacing metals?

For some structural components, a substitution assessment can be conducted, but the load, working temperature, creep, fatigue, safety factor and service life must all be verified. It cannot be determined solely based on the glass fiber content.

03.Can LGF40 PA66 be used in high-temperature environments?

PA66 has a certain heat resistance capacity, but the actual usable temperature needs to be determined by considering the heat distortion temperature, long-term thermal aging, load and medium environment comprehensively.

04.How to determine if the material is suitable for my component?

By providing information such as the component's purpose, stress conditions, working temperature, molding method and target performance, a further assessment of the material grade and verification plan can be conducted.
