LFT-D PA6 Long Carbon Fiber modified plastic high toughness strength 12mm sample available

What is PA6?

Nylon6 (PA6), also known as polyamide 6, English name: Polyamide6 or Nylon6, PA6 for short; That is, polycaprolactam, obtained from caprolactam ring-opening polycondensation. It is translucent or opaque opalescent resin, with superior mechanical properties, stiffness, toughness, wear resistance and mechanical shock absorption, good insulation and chemical resistance. Widely used in automotive parts, electronic and electrical parts and other fields.

What are the advantages and disadvantages of PA6?

Main advantages of PA:

1. High mechanical strength, good toughness, high tensile and compressive strength.

2. outstanding fatigue resistance, parts after repeated bending can still maintain the original mechanical strength.

3. high softening point, heat resistant.

4. smooth surface, small friction coefficient, wear-resistant.

5. corrosion resistance, very alkali and most salts, also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants.

6. with self-extinguishing, non-toxic, odorless, good weather resistance.

7. Excellent electrical performance. Good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can be used as power frequency insulation material, even in high humidity environment still has good electrical insulation.

8. light weight, easy to dye, easy to form.

Main disadvantages of PA:

1. easy to absorb water. High water absorption, saturated water can reach more than 3%. The dimensional stability and electrical properties are affected to some extent, especially the thickening of thin-walled parts. Water absorption also greatly reduces the mechanical strength of plastics.

2. Poor light resistance. In a long-term high temperature environment, it will oxidize with oxygen in the air, turn brown at the beginning, and then break and crack.

3. injection molding technology requirements are more strict: the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing.

4. will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials.

There are many advantages of PA6, but also many disadvantages, these disadvantages limit the play of the advantages, so people thought of modifying methods to enhance its application.

What is the Long Carbon Fiber reinforced PA6?

Long carbon fiber reinforced composites offer significant weight savings and provide optimum strength and stiffness properties in reinforced thermoplastics. The excellent mechanical properties of long carbon fiber reinforced composites make it an ideal replacement for metals. Combined with the design and manufacturing advantages of injection molded thermoplastics, long carbon fiber composites simplify the re-imagining of components and equipment with demanding performance requirements. Its widespread use in aerospace and other advanced industries make it a "high-tech" perception of consumers - you can use it to market products and create differentiation from competitors.

What is the differences between Long Carbon Fiber and Short Carbon Fiber?

Compared with the short fiber, it has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.

Frequently asked questions

1. The product is easy to brittle, so changing to use long fiber reinforced thermoplastic materials can solve this problem?

A: The overall mechanical properties must be improved. The characteristics of long glass fiber and long carbon fiber are the advantages in mechanical properties. It has 1-3 times higher (toughness) than short fiber, and the tensile strength(strength and rigidity) is increased by 0.5-1 times.

2. Are there any special progress requiremets of long carbon fiber injection molding products?

A: We must consider the requirements of long carbon fiber for the injection molding machine screw nozzle, mold structure and injection molding process. Long carbon fiber is a relatively high cost material, and need to evaluate the cost performance problem in the selection process.

3. The cost of long fiber products is higher. Does it has a high recycling value?

A: The thermoplastic LFT long fiber material can be recycled and reused very well.
