At Emco Industrial Plastics, we are one of the leading distributors of plastic materials in North America. We maintain a broad selection of engineering, high-performance, and commodity plastics in various forms—including sheet, rod, tube, profile, and film—to accommodate different customer needs. For example, we offer nylon 6 (a cast nylon material) in glass-filled variants.  

Overview of Nylon

Nylon is highly versatile. Due to its many advantageous properties, it finds use in many industries and industrial applications, making it one of the most widely used engineering thermoplastics. For example, its lighter material weight, toughness, impact resistance, and thermal resistance (up to 180º F) make it well suited for the manufacture of mechanical and electrical components. Additionally, it often serves as a replacement for aluminum, brass, bronze, steel, and other metals in assemblies that require the reduction of weight and/or noise stemming from metal-to-metal contact.

The material is available in numerous variations, each of which varies slightly in composition and, consequently, properties exhibited. The commercially available types include nylon 6, nylon 4/6, nylon 6/6, nylon 6/10, nylon 6/12, nylon 11, and nylon 12. The numerical qualifiers indicate the ratio of carbon atoms in the diamine and dibasic acid monomers used in the manufacture of the material (e.g., nylon 6/6 has six carbon atoms in the diamine acid monomer and six carbon atoms in the dibasic acid monomer).

Properties, Advantages, and Applications of Glass-Filled Nylon

Nylon manufacturers can also include various additives and fillers to improve or enhance the properties of the material. For example, adding glass powder or fibers can increase its strength and rigidity. Compared to standard nylon, glass-filled nylon generally offers the following advantages:

  • Up to 80% greater stiffness 
  • Up to 70% greater tensile strength
  • Approximately 50% of the thermal expansion rate
  • 50% greater material hardness

However, the actual properties and performance of the final material are highly dependent on the base composition and the amount of glass content added. For example, nylon 6/6 with 30% glass content has the following properties:   

  • Light material weight
  • Low coefficient of friction
  • High tensile strength
  • High elasticity
  • High thermal resistance
  • Resistance to abrasion, vibration, and wear
  • Resistance to a variety of chemicals, alkalis, dilute acids, and oxidizing agents
  • Moisture absorbent
  • Low permeability when exposed to gasoline, mineral oil, and fluorocarbon-refrigerant

The unique characteristics of glass-filled nylon make it perfect for use in a wide range of industries and industrial applications. Typical use cases include:

  • Appliances
  • Bearings
  • Brake fluid reservoirs
  • Business machines
  • Cooling fans
  • Door-latch hardware
  • Industrial equipment
  • Molded fender extensions
  • Speedometer gears
  • Timing sprockets
  • Washers and stampings
  • Windshield wiper parts
  • Wire connectors

What are the Properties, Advantages, & Applications of Glass-Filled Nylon 6?

Nylon 6 is a tough and abrasion-resistant nylon variant. Compared to nylon 6/6, it offers better surface appearance properties and processability and requires lower molding temperatures with less risk of mold shrinkage. Additionally, it generally offers good impact strength and energy-absorbing characteristics, both of which increase as moisture content rises. By adding glass beads or fibers to the material, plastic manufacturers can improve its mechanical and thermal performance even further. Glass-filled nylon 6 is typically used in applications that require a tough and wear-resistant material with excellent lubrication properties.
