Septa Materials Private Limited · Mumbai, India

Thermal protection and interface materials for India's EV and data centre infrastructure.

Specified. Sourced. Supported. We supply thermal-propagation barrier and interface materials for India's EV and data centre sectors — with material selection, documentation, and application evaluation support that helps customers navigate their AIS-038 Rev.2 and AIS-156 validation programmes.

What We Do

Three ways we create value other material suppliers cannot.

01
Technical Import Supply

We source specialty thermal and fire protection materials from qualified international manufacturers — materials India does not produce domestically. We handle all import logistics, quality verification, and local delivery. Customers get the right material without the complexity of importing it themselves.

02
AIS Battery Safety Material Support

We support Indian EV battery manufacturers through the material selection, sourcing, documentation, and application evaluation stages of their AIS-038 Rev.2 and AIS-156 thermal propagation validation programmes. The battery manufacturer owns the final compliance case. Septa provides the materials, documentation, and technical support to strengthen it.

International Manufacturer Representation

We represent selected international specialty materials companies seeking India market access — acting as their technical and commercial presence in India. This gives Indian customers access to materials and expertise from global leaders, with India-local support, pricing, and service.

Our Materials

Materials selected around the application — not from a catalogue.

Every material Septa supplies is chosen for a specific application requirement, a specific standard, and a specific operating environment. We do not supply generic products. We supply the right material for the problem.

Platform 01 · Thermal Protection
Thermal Runaway Propagation Barrier

Mica-ceramic composite sheets that stop thermal runaway propagating between battery cells. AIS-038 mandatory. Flexible, die-cuttable, and supplied with AIS-038 integration guidance as standard.

High-temperature rated — grade, thickness & test method confirmed per supplier datasheet
Dielectric strength: >8 kV/mm
Flexible — die-cuttable to exact cell dimensions
For customer-led REESS safety evaluation under AIS-038 Rev.2 & AIS-156

Platform 02 · Thermal Interface
Electrically Insulating TIM (EI-TIM)

Boron nitride silicone pads that conduct heat away from power electronics while maintaining full electrical isolation at 800V+. For EV inverters, on-board chargers, and data centre power distribution where a standard thermal pad is not sufficient.

Thermal conductivity: 5–12 W/(m·K)
Dielectric strength: >10 kV/mm
Temperature range: −40°C to +200°C
Volume resistivity: >10¹² Ω·cm

Why Septa

What makes Septa different from every other material supplier.

We are not a general rubber or industrial products distributor. We are a specialist — with focused expertise in thermal management and fire protection materials for India's EV and data centre markets. That specificity is what creates value for our customers.

01
Application Engineering Included

Every material we supply comes with application guidance. We help customers integrate, test, and document — not just supply and invoice.

02
India-Local with Global Sourcing

We are based in Mumbai with the ability to source from qualified international manufacturers. Customers get global material quality with local service, pricing, and response times.

03
AIS-038 Compliance Expertise

We specifically support the test that Indian EV manufacturers fail most often. Our service goes beyond the material — to helping customers pass the certification.

04
No Minimum Order Complexity

International manufacturers often have large MOQs, USD invoicing, and 8-12 week lead times. Septa solves all of this — supplying in Indian quantities, in rupees, from local stock.

How We Work

From requirement to qualified material in six steps.

01

Understand the Requirement

We begin with the application, the environment, the standard, and the performance needed.

02

Material Selection

We identify the right material chemistry, specification, and form factor from our supplier network.

03

Sample & Test

Samples supplied with relevant test data. We support in-house and third-party testing at ARAI or NABL labs.

04

Integration Support

We support application evaluation and documentation for the customer's validation programme. The battery manufacturer owns the compliance case; Septa provides material data, test coordination support and technical documentation.

05

Qualification

We support the customer through formal material evaluation, vendor qualification, and technical documentation. Final REESS or vehicle-level compliance is owned by the manufacturer through their approved test agency.

06

Supply & Support

Ongoing supply with consistent quality, responsive service, and technical support as applications evolve.
