// THE FIVE NON-NEGOTIABLES
01 / EXCELLENCE

Spec, not shortcut.

Compounds, tolerances and finish held to the standard your application demands — not the one that's easy.

02 / PRECISION

Dimensional discipline.

To drawing. To spec. Batch after batch, with the same numbers.

03 / HONESTY

Real prices. Real dates.

What's possible, what isn't, what it costs and when it ships — all stated upfront, in writing.

04 / DELIVERY

On time, every time.

Promised dates, met. If anything threatens that, you hear about it early — never late.

05 / RELATIONSHIP

Built to last.

We treat customers the way the partnership itself is built — for the long term. Relationships measured in years, not orders.

The catalogue.

Six categories, custom to your drawing or sample. Across six base polymers — Silicone, EPDM, FKM, NBR, Neoprene, SBR — and the hundreds of compounds we formulate from them.

01 / MOULDED

Gaskets & Seals

Complex geometry seals for pressure and temperature cycling.

02 / EXTRUDED

Profiles & Channels

Custom cross-sections. Any length, constant section.

03 / MOULDED

O-Rings

All major sizes and compounds. Static and dynamic sealing.

04 / MOULDED

Grommets

Cable and wire sealing for IP67/68 enclosure designs.

05 / EXTRUDED

Foam profiles and strips at low compression force.

06 / EXTRUDED

Silicone Strips

Extruded silicone strips and tapes for sealing, masking and gasketing.

07 / MOULDED

Bushes & Anti-Vibration Pads

Moulded bushes, mounts and pads that damp shock and noise — rubber-to-metal bonded.

08 / CUSTOM

Bespoke to Drawing

Send drawing, sample or spec. We engineer what you describe.

// Materials

Six base polymers, hundreds of compounds.

Silicone is our specialism — but we mould and extrude across the full range, formulating each polymer into the exact compound your part needs. Click any material for properties, strengths and where it fits.

// EPDM

EPDM

Outstanding weather, ozone, steam and hot-water resistance — built for the outdoors.

View details →
// SILICONE (VMQ) specialist

Silicone

Widest temperature range, excellent UV, weather and electrical insulation. Moulded and extruded — our core material.

View details →
// NBR (NITRILE)

NBR

Excellent oil, fuel and abrasion resistance — the workhorse for industrial seals.

View details →
// FKM (VITON-TYPE)

FKM

High-heat with oil, fuel and chemical resistance for the most aggressive duty.

View details →
// SBR

SBR

Cost-effective abrasion and impact resistance for general-purpose parts.

View details →
// NEOPRENE (CR)

Neoprene

A balanced all-rounder — weather, moderate oil and flame resistance in one.

View details →
// CAPABILITIES

From drawing to finished part — in-house, end-to-end.

Design, compound, tooling and production, all under one roof. We read the drawing, choose the compound, build the tool and make the part — not parts off a shelf, but the whole chain under one partnership.

01 / DESIGN & PROTOTYPING

Read it. Prove it.

Work from your drawing or sample, prototype the part, and prove it before committing to tooling.

02 / COMPOUND SELECTION

The right elastomer.

Match the compound to the application — Silicone, EPDM, FKM, NBR, CR or SBR — for the chemistry, heat and load it has to take.

03 / MOULDING

Moulded to geometry.

Compression moulding and rubber-to-metal bonding — complex parts held to drawing, batch after batch, with the same numbers.

04 / EXTRUSION

Constant section.

Continuous profiles and channels in custom cross-section — any length, the same section throughout.

05 / TOOLING

Built for your part.

Tooling cut to your geometry, not adapted from something close enough.

06 / IMPORT SUBSTITUTION

Source it here.

Replace imported components with locally engineered equivalents — same spec, a shorter supply chain.

// INDUSTRIES WE SERVE

Made for your industry.

Custom rubber seals, gaskets, grommets and profiles for manufacturers across India — from electrical and lighting to automotive, EV, batteries and solar. If the part is hard to source, that is exactly what we make.

// ELECTRICAL

Electrical

Custom seals, gaskets and cable grommets that keep dust and moisture out of electrical enclosures, connectors and assemblies.

// LIGHTING

Lighting

Weatherproof silicone gaskets and seals that keep LED fittings and light fixtures sealed, indoors and out.

// SWITCHGEAR

Switchgear

Insulating moulded and extruded rubber parts for switchgear and power-distribution equipment.

// INDUSTRIAL OEMs

Industrial OEMs

Made-to-drawing rubber components for OEMs — the non-standard part, engineered exactly to your spec.

// DEHUMIDIFIERS & HVAC

Dehumidifiers & HVAC

Sealing gaskets, drain seals and anti-vibration pads that keep HVAC and dehumidifier units quiet and leak-free.

// AUTOMOTIVE & EV

Automotive & EV

Seals, grommets and anti-vibration mounts for automotive ancillaries and electric-vehicle assemblies.

// BATTERIES

Industrial & Car Batteries

Vent seals, terminal gaskets and enclosure seals for industrial and automotive battery packs.

// RENEWABLE & SOLAR

Renewable & Solar

Weatherproof gaskets and cable grommets for solar junction boxes, inverters and outdoor enclosures.

THE PARTNERSHIP

Two partners. Decades each.

Exonel is a new firm — but not new ground. Its founders bring decades of operating experience: one in rubber design and manufacturing, the other in finance and operations. Both pointed at one thing — doing it the right way, for customers who know the difference.

FOUNDING PARTNER · DESIGN & MANUFACTURING
20+ years as a rubber technologist — designing, prototyping and manufacturing moulded and extruded components, including rubber-to-metal bonded parts, in Silicone, EPDM, FKM, NBR, CR and SBR. An engineer first: he formulates the compound to the hardness, temperature and chemical resistance an application needs, reverse-engineers a part from a worn sample, and designs for manufacture before a tool is cut. Solves the sealing, vibration and import-substitution problems where standard catalogue parts won't do — for electrical, lighting, switchgear and industrial OEMs.

// FAQ

Common questions.

What types of rubber does Exonel manufacture?

We work across six base polymers — Silicone, EPDM, FKM (Viton-type), NBR (nitrile), Neoprene (CR) and SBR — formulated into hundreds of compounds, and match the right one to the heat, chemicals and load your part will see.

Can you make custom rubber parts to a drawing or sample?

Yes — bespoke work is most of what we do. Send a drawing, a sample, or even a description, and we engineer the moulded or extruded part to match it.

What is the minimum order quantity (MOQ)?

It depends on the part, compound and process. Tell us what you need and we'll confirm the right quantity for your job — just get in touch.

Which industries does Exonel supply rubber components to?

Electrical, lighting, switchgear, HVAC and dehumidifiers, automotive and EV, batteries, and solar and renewables — for manufacturers and OEMs across India, including parts that replace imports.

Can you help me choose the right rubber compound?

Absolutely — picking the elastomer and hardness is part of the job. We'll recommend the compound suited to your temperature, chemical and load conditions before any tooling is cut.

How do I get a quote from Exonel?

Send a drawing, sample or description by email at email@exonel.in or on WhatsApp, and we'll come back with a material recommendation and a quote.

Where is Exonel based, and do you supply across India?

We manufacture in-house in Howrah (Kolkata), West Bengal, and supply rubber components to customers across India.

Who manufactures custom silicone rubber components near Kolkata?

Exonel Industries manufactures custom silicone rubber components in-house in Howrah (Kolkata), West Bengal — moulded and extruded seals, gaskets, profiles, cords and sponge — supplied to manufacturers across India.

Can you supply a local alternative to an imported rubber part?

Yes — import substitution is core to what we do. Send the imported part, a sample or a drawing, and we'll work to a locally made equivalent in the right compound.

What temperature can silicone rubber withstand?

Silicone (VMQ) typically performs from about −60°C to +200°C — far wider than most rubbers — which is why it suits lighting, electrical and high-heat sealing. Exact grades are matched to the application.
