Nylon 6 vs Nylon 66: Which Manufacturers Lead in India?

 Nylon is one of the most versatile engineering thermoplastics widely used in automotive, textiles, packaging, and industrial applications. Among its different grades, Nylon 6 and Nylon 66 dominate the market due to their unique mechanical strength, durability, and chemical resistance. While both have similarities, their properties differ in ways that make them suitable for specific applications. In India, the demand for both these polymers is rising rapidly, leading to the growth of strong networks of nylon 6 manufacturers in India and nylon 66 manufacturers in India.

Understanding Nylon 6 and Nylon 66

What is Nylon 6?

Nylon 6 is produced from a single monomer, caprolactam, and is known for its excellent toughness, high impact resistance, and good surface finish. Its lower melting point (around 220°C) makes it easier to process, making it widely used in textiles, films, industrial yarns, and injection-molded components.

What is Nylon 66?

Nylon 66 is synthesized from two different monomers—hexamethylene diamine and adipic acid. It has a higher melting point (around 265°C), better wear resistance, and superior thermal stability compared to Nylon 6. These characteristics make it a preferred choice for automotive under-the-hood parts, electrical connectors, and high-performance engineering components.

Nylon 6 vs Nylon 66: Key Differences

PropertyNylon 6Nylon 66
Melting Point~220°C~265°C
Moisture AbsorptionHigherLower
ToughnessBetter impact resistanceBetter stiffness and strength
ApplicationsTextiles, films, yarns, packagingAutomotive, electrical, heavy-duty machinery
CostRelatively lowerSlightly higher due to production

This comparison shows why Nylon 6 is more common in cost-sensitive applications like packaging and fabrics, while Nylon 66 leads in engineering-grade uses where strength and heat resistance are critical.

Growing Demand in India

India has become one of the fastest-growing markets for engineering plastics, driven by the automotive, electrical, and textile industries. As manufacturers look for high-performance polymers, both Nylon 6 and Nylon 66 are witnessing a surge in demand.

  • Automotive Sector: With the shift towards lightweight vehicles, Nylon 66 is increasingly replacing metals in structural and under-the-hood parts.

  • Textile Industry: Nylon 6 dominates due to its superior dyeability, smooth texture, and lower cost.

  • Industrial Applications: Gears, bearings, and machine parts often prefer Nylon 66 for its higher thermal stability.

Leading Nylon 6 Manufacturers in India

Several companies specialize in producing Nylon 6 to meet domestic and export demands. Key nylon 6 manufacturers in India include:

  • SRF Limited – Known for high-quality Nylon 6 used in textiles and industrial yarn.

  • Gujarat State Fertilizers & Chemicals (GSFC) – A major producer of caprolactam and Nylon 6 chips.

  • JCT Limited – Supplies Nylon 6 for textile and engineering applications.

These players ensure consistent supply, catering to industries ranging from packaging to engineering plastics.

Leading Nylon 66 Manufacturers in India

Compared to Nylon 6, Nylon 66 has fewer large-scale producers in India, but the market is expanding due to rising demand in engineering plastics. Prominent nylon 66 manufacturers in India include:

  • RadiciGroup (India operations) – Provides advanced Nylon 66 grades for engineering applications.

  • BASF India – Supplies Nylon 66 resins for automotive and electrical components.

  • Ascend Performance Materials (via distributors) – One of the world’s largest Nylon 66 producers with a presence in the Indian market.

Local compounding companies are also investing in Nylon 66 production, enabling more cost-effective solutions for Indian manufacturers.

Case Study: Nylon in the Indian Automotive Industry

A leading automobile manufacturer in India recently shifted from using metal components to Nylon 66 in its engine housing and radiator end tanks. This change resulted in:

  • 30% weight reduction of the component.

  • Improved fuel efficiency due to lightweighting.

  • Lower production costs through easier molding and reduced machining.

This example demonstrates how Nylon 66 is becoming a crucial material in India’s growing automotive sector.

Conclusion

The choice between Nylon 6 and Nylon 66 depends on the application requirements. Nylon 6 remains a favorite for textiles, packaging, and cost-sensitive industries, while Nylon 66 leads in engineering plastics, automotive, and electrical applications.

With strong networks of nylon 6 manufacturers in India like SRF and GSFC, alongside global leaders supplying nylon 66 manufacturers in India, the country is well-positioned to meet rising demand across multiple sectors. As industries push for lightweight, durable, and sustainable solutions, both Nylon 6 and Nylon 66 will continue to play a pivotal role in shaping India’s manufacturing landscape.
