DDev Plastiks is India’s largest listed manufacturer of polymer compounds - the customised plastic pellets that go into every power cable, solar wire and industrial bag - with a legacy stretching back over four decades and three generations of the founding family. The business was carved out of Kkalpana Industries in 2022 and listed on the BSE that same year, but its compounding roots go back to a PVC unit in Daman in 1985 and a pivotal 2006 bet on a Swiss Buss Kneader that made it the first Indian producer of high-voltage XLPE insulation compound. The recurring approach is to spot a compound that Indian cable makers are importing, build the first domestic capacity for it, and then lock in customers with faster customisation and zero-defect consistency - a playbook it has now extended from wires into the energy-storage systems that stabilise renewable power grids. # Business segments A single compounding engine with two distinct value-creation stages - the core polymer-compound franchise that generates the cash, and an emerging battery-assembly vertical that uses that cash to build a second platform for the energy transition. ## 1. Polymer compounding: the cash engine that feeds every Indian cable maker **The company takes raw plastic granules, cooks them with flame-retardant and conductive additives, and sells the resulting pellets to virtually every major wire and cable manufacturer in India - with roughly one of every three tonnes of cable compound used in the country coming from its plants.** - **More than 200 custom grades, not one commodity** - the portfolio spans five product families: PVC compounds for construction wire, XLPE and Sioplas compounds for medium- and high-voltage power cables, engineering plastics for white goods, halogen-free flame-retardant (HFFR) compounds for public-building and solar cables, and filled compounds for packaging sacks. Each grade is a recipe of base polymer plus additives that alter conductivity, flame resistance or tensile strength to a specific customer’s process, so switching costs are high. - **First-mover in high-voltage insulation** - it was the first in India to install a Buss Kneader for medium-voltage XLPE compound in 2006, and remains the only domestic player offering compounds rated from 66 kV up to 72 kV, with R&D now targeting 132 kV and 220 kV for commercial readiness by FY29. Its water-tree-retardant XLPE compound passed a two-year test at Germany’s VDE laboratory, which acts as a passport for export customers. - **Raw-material cost passed through, not absorbed** - the pricing model is designed so that a one-rupee move in PVC resin changes the product price by about fifty paise, while for polyethylene-based compounds the pass-through is nearly one-to-one. Orders and raw-material purchases are lined up simultaneously, and inventory is held for at most a month, so the company carries very little commodity-price risk on its book. - **Six plants placed to catch imports and feed customers** - manufacturing units in West Bengal, Daman and Silvassa sit along both coasts, close to ports where polymer is imported from the Middle East and Europe, and near the domestic cable-making clusters that buy 61% of output. The multi-location setup cuts freight both on the way in and on the way out. - **Exports as a quality stamp, not just volume** - roughly a quarter of revenue comes from over 55 countries, with marquee names like Nexans, Prysmian and Ducab on the customer list, and underwriters’ approval for direct Americas sales in progress. The company carries a record of zero rejections, which matters in an industry where a failed batch can shut a cable line. ## 2. Battery energy storage: the next compounding play, applied to the grid **DDev is building a battery-pack assembly business that will buy cells, marry them with its own thermal-management and power-electronics know-how, and sell finished storage systems to the solar and utility EPC companies that need to smooth out intermittent renewable power.** - **Assembler, not cell manufacturer** - the model is to procure lithium-ion cells and integrate them into containerised or cabinet-based storage systems, positioning the company as a supplier to EPC players and storage integrators rather than a cell-chemistry player. This keeps the capital requirement to roughly ₹150-200 crores for the first 5 GWh of annual assembly capacity, funded from internal accruals. - **Revenue from the second half of FY27** - Phase 1 targets a 5 GWh facility by Q3 FY27, with the segment expected to start contributing to the top line from the second half of that year and to be reported as a separate business segment from that point. Each gigawatt of capacity is projected to generate roughly ₹800-900 crores of revenue, so the vertical could add ₹2,000-2,500 crores on top of the compounding target by FY30. - **R&D centre built in from day one** - the BESS initiative includes a dedicated advanced-battery R&D centre, mirroring the compounding playbook where in-house formulation capability became the moat. # Group structure and partners **The company sits under a tightly held promoter group, buys key raw materials from a fellow subsidiary, and pays a royalty for the brand name that the market still recognises.** - **Controlled by Bbigplas Poly Private Limited**, which holds roughly 74% of the shares, with Mr. Narrindra Suranna as Chairman and Managing Director and Mr. Ddev Surana as Whole-Time Director and CEO. - **Kkalpana Industries is both sibling and supplier** - KIIL, a fellow subsidiary, trades in and manufactures specialty compounds that are a critical raw material for DDev, and its large-scale procurement gives DDev better negotiated prices. DDev pays KIIL a branding fee of ₹1 per kilogram of finished goods, capped at ₹15 crores a year, for continued use of the KIIL brand name, trademarks and centralised procurement muscle. - **No subsidiaries or joint ventures** - as of the latest annual report, the company operates as a single entity with no associate or subsidiary companies, though it had earlier announced plans for a wholly owned subsidiary in Saudi Arabia that do not appear to have been completed.
