PA66 enhanced flame retardant grade

PA66 shielded nylon application of electronic, automotive electronics and other integrated circuit packaging, electromagnetic shielding, etc.

Modified nylon

Due to the strong polarity of PA nylon, hygroscopicity is strong, and the dimensional stability is poor, but it can be improved by modification. According to statistics, 70% of nylon materials used in a car for the modified nylon! It can be seen that the advantages of modified nylon.

Modified nylon is a class of engineering plastics , is based on nylon raw materials as the base material to change the physical properties of the formation of granular products, nylon color can be produced according to customer requirements.

Modified nylon is roughly divided into:

1, enhanced nylon

2, flame retardant nylon

3, transparent nylon

4, wear-resistant nylon

5, toughened nylon

Reinforced nylon

In the polyamide mixed with a variety of fibrous materials

Single casting

Features:

⑴ high molecular weight

⑵ simple process, product shapes and diverse

⑶ can be made of large mechanical parts

⑷ low water absorption

Aromatic

In the main chain in the introduction of benzene ring structure products high temperature, radiation resistance, corrosion resistance

Amorphous class

Amorphous transparent nylon

High transmittance, good dimensional stability

characteristic

1. Thermal properties: glass transition temperature (T g) and melting point (T m); high heat distortion temperature (HDT); long-term use of high temperature (UL- 746B); use temperature range; small thermal expansion coefficient.

2. Mechanical properties: high strength, high mechanical modulus, low latency, strong wear resistance and fatigue resistance.

3. Other: chemical resistance, electrical resistance, flame resistance, weather resistance, good dimensional stability.

Modified nylon features:

Injection grade modified nylon, injection grade enhanced nylon 66 material has good dimensional stability, high temperature resistance, easy processing and easy mold release. Division I can be based on customer needs different research and development; production, all materials can provide relevant testing and certification! Support customers to the relevant authority to detect testing agencies.
