Since 2014, GRP has pioneered the recycling of polyamide from end-of-life tyres in India. Our Engineering Plastics division manufactures high-performance Nylon 6, Nylon 66, and PBT - leveraging inter-unit synergies and upcycled raw materials to replace 3000 MT of virgin polymers annually. Every product is rigorously tested and certified to meet demanding engineering standards.
GRP’s repurposed Nylon 6 compounds, both unfilled and glass- filled, are produced from recycled polyamide sources such as tyre cords, processing wastes and ocean wastes. The unfilled grade offers excellent impact resistance, wear properties, and ease of processing. The glass- filled grade, with up to 50% glass fiber, delivers enhanced tensile strength, stiffness, thermal stability, and dimensional accuracy. These sustainable compounds are engineered for automotive, electrical & electronics, and industrial applications requiring high performance and durability.
For applications requiring very high mechanical and thermal properties, Nylon 6 is reinforced in various combinations of reinforcing materials depending on the properties required and applications
Typical glass filled combinations includes 15% glass filled Nylon 6, 30% glass filled Nylon 6, 35% glass filled Nylon 6
Nylon 6 is a semi-crystalline synthetic polymer, produced from Polymerization of caprolactam. It is also known as Polyamide 6 or PA6 and has great demand due to its strength, high abrasion resistance, surface appearance and process-ability compared to Nylon66. Nylon 6 is used in various forms like prime polymer, reprocessed granules, scrap, lumps, modified Nylon 6 for high performance, blends & compound
