General Properties of Nylon Plastic –

• Interesting strength and stiffness at relatively high temperatures.
• Outstanding electrical insulation properties
• Low dimensional stability
• Great impact strength (even at low temperatures)
• Good fatigue resistance
• Fantastic oil and fuel resistance
• Dyeing is a must before processing
• Good fatigue resistance
• Meagre dimensional stability
• Susceptible to attacks from mineral acids and polar solvents
• Nylon melt point is relatively high because nylons are polyamides and formed by the reaction of an amine with an acid. The amide group is responsible not just for Nylon’s high melting point, but also responsible for its strength and natural harmony with moisture.
• Nylon can easily be flame retarded which is quite rare to be found in thermoplastics.

Advantages and Disadvantages –

 Advantages:

• Smooth processing ans easy machining.
• Outstanding wear-resistance and abrasion
• Excellent tensile and compressive strength.
• Super lightweight compared to other thermoplastics. 1/7th in weight compared to mainstream thermoplastics such a polypropylene, polystyrene, polycarbonate, etc.
• Intricate designs are easily achievable.
• Excellent dust and dirt resistance.

Disadvantages:

• The infamous high melting temperature can become a nuisance in certain applications.
• Highly flammable. Catches fire easily in an open fire.
• Not compatible with UV exposure. Additional UV-proof coating must be added for UV protection.

Applications:

Typical Applications:

• Wheels
• Gloves
• Toothbrushes
• Medical implants
• Electrical connectors
• Fishing lines
• Tents
• Gears
• Tennis racket strings
• Guitar strings and pics
• Tents
• Wear pads

Construction: tubes, pipes, sheet ods, pipes, screws, plumbing fittings, industrial hammerheads, crane pads, etc.

Electrical: Switchgear, circuit insulation board, machine guards, seals, electronic test equipment, jigs & fixtures, rotor slot wedges, gears, replacement components, wear strips & chain guards.

Automotive: door handles & radiator grills.

FAQs – 

1. Which is more water-resistant? Nylon or Polyester.

Ans. Polyester is more water-resistant than Nylon. However, none of them is completely waterproof. Nylon has a moisture regain the level of 4%, whereas polyester has a moisture regain the level of 0.4%. Meaning, polyester is more hydrophobic than Nylon.

2. How do you clean Nylon Plastic?

Ans. It is quite easy to clean, but it should be done carefully because nylon resists absorbing moisture and dries easily. Handwashing is the easiest and safest way to clean Nylon products. Rinsing with cool water until the water is no longer soapy and doesn’t wring.

3. What is the reason behind Nylon’s high melting point?

Ans. Nylon is formed by amide groups with more intermolecular interaction making the attractive force also high. Tat actor makes both the melting point and mechanical properties more robust.

4. What is the main difference between Nylon and polypropylene?

Ans. Nylon and polypropylene are drastically different materials from each other. Polypropylene looks and feels very dull compared to nylon which feels silky. Polypropylene is a prime replacement for wool and cotton, whereas, nylon is a replacement for silk.

5.  What is the material density of Nylon?

Ans. 1.15 g/cm3.

That was all I wanted to say about the Nylon melting point and its other attributes. Thsi was a short piece and I’ll keep sharing such short and informative articles shortly.
