India EV Conclave 2026 Highlights Next-Generation Materials for Electric Vehicle Manufacturing

November 13, 2026

India EV Conclave 2026, organised by Autocar Professional on October 27 at the Hyatt Regency in New Delhi, included a technical session on next-generation EV materials. According to Autocar Professional's November 11 coverage, Ascend Performance Materials presented a cross-linked polyamide compound designed for potential use in battery thermal runaway protection applications. Its reported performance claims remain subject to application-specific testing and validation. Most of the conclave's agenda focused on demand, ownership economics and localisation. Materials featured in technical presentations, and the coverage reviewed is largely company-led.

What is India EV Conclave 2026?

India EV Conclave 2026 is Autocar Professional's annual conclave, themed "Electric Mobility 2.0: Ideas, Innovations & Impact on India". The one-day event covered EV adoption, ownership economics, localisation and the supply chain.

Speakers included the Ministry of Heavy Industries' Additional Secretary Dr Hanif Qureshi and executives from Tata Motors, Mahindra, Hyundai, ZF Group, Ather Energy and Amara Raja. Technical presentations came from Ingersoll Rand, Neenjas Electric and Ascend Performance Materials.

What Next-Generation EV Materials Were Discussed?

The materials coverage centres on Ascend's technical presentation, by Anton Kumanan, Technology Leader for India. He described Starflam X-Protect, a polyamide 66 compound in which electron-beam treatment creates cross-links after conventional injection moulding.

According to the report, standard polyamide 66 loses stiffness as it nears its melting range of roughly 240 to 260 degrees Celsius. Kumanan said the material "nearly becomes a thermoset" after cross-linking. It targets components exposed to heat during battery thermal runaway.

According to Kumanan, the material could provide more than two minutes of additional protection during a battery thermal runaway event. This is a supplier-reported performance claim, and actual protection would depend on component design, testing conditions and validation within the vehicle's battery system. He noted that actual performance depends on the extent of cross-linking, part design and validation for each application. This is a supplier claim and not independent test data.

What Other Materials and Applications Were Mentioned?

Ascend also described overmoulded busbars, which need electrical insulation and heat resistance, and said it is working on them with global automakers. It presented HiDura PA610 and PA612, specialty polyamides reported to absorb less moisture than PA6 and PA66, helping to preserve dimensional stability.

The company said certain materials retained more than 50% of their properties after 1,000 hours of exposure to automotive coolants and fuels. These are company statements.

In a separate premium-EV panel reported on October 28, speakers cited sustainable materials and interior craftsmanship as brand differentiators. They also discussed NMC and LFP battery chemistries. No specific material or performance data were reported from that panel.

How is the Localisation Angle Developing?

Ascend entered India in 2022 by acquiring Chennai-based Formulated Polymers, and operates a compounding facility in Chennai. It plans to make Starflam X-Protect in India. Its proposed route is a ready-to-use compound from Ascend, parts moulded by a Tier 1 supplier, electron-beam treatment at an industrial facility, and validation in the battery system with OEM support.

Kumanan said industrial-scale cross-linking capacity already exists in India. The company is also building simulation capability at IIT Madras Research Park and is seeking OEM and Tier 1 partners. Customer commitments or production dates were not reported.

What Manufacturing Technology Was Presented Alongside the Materials?

Ingersoll Rand's Vikas Bhat spoke on EV manufacturing technology, according to an Autocar Professional report dated November 6. Ingersoll Rand highlighted its role in supplying manufacturing equipment for India's EV industry, including fastening and assembly technologies designed to improve process control and traceability.

The presentation covered fastening tools that record torque and tightening data, which allows individual joints to be traced. These tools can be mounted on robotic arms, and Bhat cited two-wheeler lines running at about 13 to 14 seconds per vehicle.

The report named no specific materials. It is relevant here because new materials and joining methods depend on process control and traceability on the line.

What Else Did the Conclave Say About the Supply Chain?

The concluding panel was titled "Building India's EV Ecosystem: Localisation, Self-Reliance and Competitiveness". It included speakers from ACMA, ZF Group, Amara Raja Group, Ather Energy and ASDC. The coverage reviewed does not report specific outcomes from that panel on materials.

In the premium-EV panel, Brar of BMW India said long-range vehicles need NMC chemistry for energy density. BYD's Rajeev Chauhan highlighted LFP Blade batteries for thermal stability. These are executive statements on battery chemistry, not independent assessments.

Why Are Advanced Materials Important for EV Manufacturing?

Material choice affects safety, weight, thermal performance, cost and manufacturability. In EVs, heat from the battery and power electronics, and the need for range, make these trade-offs sharper than in many conventional vehicles. The conclave coverage does not discuss aluminium alloys, composites or high-strength steel. The examples below are broader industry context and were not reported from the conclave.

How Do Lightweight Materials Affect Component Design, and What is Used in Battery Enclosures?

Lightweight vehicle structures can improve range or allow smaller batteries, but they bring design constraints. Aluminium alloys, advanced composites and high-strength steel each differ in stiffness, joining methods, tooling and repair. Battery enclosure materials are commonly steel, aluminium or composites, chosen for crash protection, sealing, thermal behaviour and fire containment. Thermal management materials are selected for heat conduction and flame resistance. The best choice depends on the vehicle and the cost target.

How Can Advanced Materials Affect Costs, and What Challenges Do Manufacturers Face?

New materials can lower weight or improve safety, but may raise material cost, tooling cost or process complexity. Ascend's route, for example, adds an electron-beam step after moulding. That adds a processing stage and a dependence on cross-linking capacity. Challenges for suppliers include material testing and validation, supplier qualification, reliable sourcing, process control and meeting automotive quality standards. Costs and timelines for the materials discussed were not reported.

The conclave showed supplier interest in new EV materials, but the evidence is early. Manufacturers should treat the claims as starting points for their own testing and qualification.

IMARC Engineering’s Perspective

The discussions at India EV Conclave 2026 highlight the growing importance of material selection, manufacturing compatibility and supplier readiness in electric vehicle component development. For EV component manufacturers and industrial project developers, adopting advanced materials requires more than evaluating product performance. It also involves assessing manufacturing processes, tooling requirements, equipment compatibility, material sourcing, testing infrastructure and production costs.

IMARC Engineering supports manufacturers through feasibility studies, DPR preparation, supplier identification, plant layout and process planning, and engineering coordination for EV component manufacturing projects. The supplier-reported developments discussed at the conclave should be treated as potential opportunities requiring independent technical evaluation, application-specific testing and commercial feasibility assessment.
