Learn about the characteristics of plastic screw materials and Application

Plastic can be said to be one of the greatest inventions of mankind in the 20th century, with its excellent plasticity, antibacterial insulation and corrosion resistance, etc. Plastic has become an indispensable basic new material for the rapid development of modern society. As a star member of the plastic family, nylon has revolutionized industrial development and human life since its birth. Compared with traditional metal screws, nylon screws have excellent performance in many aspects.

Nylon screws, nylon fasteners in our daily life is very common, nylon screws in English is plastic screws, also known as plastic, plastic screws, more common in our domestic nylon screws are mostly made of nylon 66 (NYLON66), nylon screws have insulation, non-magnetic, corrosion-resistant, beautiful, never rust and other high-quality characteristics, especially for parts of electronic products.

And modified engineering plastics, its use of strength, impact resistance and metal can be comparable, we often add 30% glass fiber in nylon 66. The mechanical properties of this modified engineering plastics is far better than ordinary nylon, with the development of nylon materials, nylon screws using a diverse range of materials, properties continue to improve, the field of application is also becoming more and more broad.

8.PA+GF-Glass Fiber Reinforced Nylon

Operating temperature:105°C Flame retardant grade:UL94HB

Reinforced nylon has excellent heat resistance, oil resistance and strong mechanical properties. It has excellent fatigue resistance and variability.

9. POM -Polyoxymethylene

Use temperature:95°C Flame retardant grade:UL94HB.

POM products are light, high stiffness, good elasticity, dimensional stability, small coefficient of friction, good electrical insulation, almost unaffected by temperature and humidity.

10. PE -Polyethylene

Use temperature:80°C Flame retardant grade:UL94HB

PE-polyethylene feels like wax, has excellent low-temperature resistance, good chemical stability, and can resist the erosion of most acids and alkalis (not resistant to acids with oxidizing properties). Insoluble in general solvents at room temperature, small water absorption, excellent insulation.

11. PEI -Polyetherimide
