It’s no secret that plastic has become a go-to material over metal and other alternatives in recent times. Today, there are numerous types of plastic resins available, each offering distinct mechanical and economic advantages. Among these, nylon resins have risen to prominence, perhaps being the first commercially successful synthetic thermoplastic polymer in the annals of plastic history. But what exactly makes nylon so popular? And how do the various grades of nylon resin stack up against one another? Keep reading to find out.
## A Brief Overview of Nylon
Nylon, commonly referred to as polyamide, is a broad family of synthetic polymers widely utilized in both household and industrial settings. These resins can be tailored with various additives to enhance their properties. They are highly versatile, capable of being melted down and shaped into fibers, films, and other forms with ease.
### Key Features That Make Nylon Stand Out
The following characteristics of nylon resins have driven their growing adoption across industries:
- Excellent temperature, creep, and chemical resistance
- High stiffness and strength
- Superior toughness and impact resistance
- Outstanding tribological properties
- Exceptional tear and wear resistance
Given these attributes, nylon is an excellent choice for processes such as injection molding, extrusion, co-extrusion, blow molding, and film production.
### Some Common Commercial Nylon Grades
Here’s a look at some of the more popular nylon resin grades found in the market:
#### Nylon 6
Also known as polycaprolactum, this semi-crystalline polyamide can be customized with stabilizers and comonomers to suit specific needs. Its fibers boast impressive tensile strength, luster, elasticity, and toughness.
#### Nylon 6/6 (or Nylon 66)
This grade is extensively used in the plastic and textile sectors due to its high stability in harsh conditions, strength, and heat tolerance. It’s often employed in the creation of injection-molded 3D structural components.
#### Nylon 4/6 (PA46)
With its high heat resistance, this grade excels in demanding environments, making it a staple in automotive under-the-hood applications.
#### Nylon 6/10
Offering low moisture absorption and robust chemical resistance, this grade is not only effective but also cost-efficient compared to other low-moisture-absorption nylon resins.
#### Nylon 11
Known as polyamide 11, this bioplastic serves diverse industries, including textiles, oil and gas, electronics, aerospace, automotive, and sports equipment. It stands out for its low water absorption and dimensional stability under heat and moisture exposure.
#### Nylon 6/12
This low-moisture-absorbing nylon provides excellent strength and chemical resistance while maintaining good lubricity and wear resistance.
#### Nylon 12
This resin combines the mechanical properties of polyolefins with those of short-chain aliphatic nylons, delivering high tensile strength, hardness, and abrasion resistance.
Most nylon resin grades are available in specialized forms such as glass fiber, aramid fiber, flame retardant, hydrolysis-resistant, nucleated, heat-stabilized, glass-beaded, carbon fiber, impact-modified, and lubricated variants.
## Applications of Nylon Resins
Nylon resins play a crucial role in manufacturing a wide range of commercial and industrial products. Here are some common examples:
- Connectors and switches
- Fasteners
- Brackets and housings
- Gears, cams, and bearings
- Vacuum cleaner handles
- Power tool housings
- Radiator tanks
- Mirror housings
- Intake manifolds
- 3D printed models
