Deep Polymers is a specialist maker of masterbatches - the tiny, colour-packed pellets that give nearly every plastic product its shade, strength, or special property - and it has quietly grown from a 600-tonne-a-year workshop into a supplier serving over 25 countries. The company was founded in Gujarat in 2005 by Ramesh Bhimjibhai Patel, a plastics-industry veteran, and its story is one of steady capacity expansion punctuated by a pivotal merger with a family partnership firm that consolidated operations and added scale. The recurring approach is to offer practically every kind of masterbatch under one roof - a breadth most rivals do not match - and to back that range with deep application support that keeps its labs and customers closely linked on new product development. # Business segments A single-engine business built around one core capability - making the concentrated additive pellets that colour and enhance plastics - with a new green-chemistry bet layered on top as an extension of the same compounding know-how. ## 1. Masterbatches and compounds: the full-spectrum colour and additive kitchen for plastics **The company makes every major type of masterbatch and filler compound, acting as a one-stop supplier of the ingredients that give plastic products their colour, function, and cost structure.** - **The full palette, from white to speciality** - it produces White, Black, Colour, Additive, Speciality, and Filler masterbatches, plus polymer compounds, covering the complete range of concentrated additives that downstream manufacturers need. Colour masterbatch alone comes in roughly 5,000 grades for different applications and shades. - **Fillers that cut costs for customers** - its Antifab-brand filler masterbatches are designed as cost-effective replacements for pure polymer, improving opacity, extruder output, and thermal stability while letting manufacturers use high loadings to reduce material expense. A talc-based version is made specifically for woven sacks and lamination liners. - **Serves industries from packaging to textiles** - end uses span household goods, furniture, bulk and film packaging, roof coverings, flexible and rigid containers, non-woven bags, and PET fibre masterbatch for textile yarn, meaning its pellets end up in everything from shopping bags to car parts. - **In-house R&D as the customer link** - a state-of-the-art lab with NABL-calibrated testing equipment lets the company develop customised, tailor-made solutions and work closely with customers on new product projects, which builds a deep understanding of what they need. - **Manufacturing at scale with German engineering** - the company runs multiple plants in Gujarat, including a newer facility equipped with twin-screw compounders from Coperion GmbH of Germany, the leader in extrusion machinery, giving it the precision to make speciality masterbatches for PET fibres. ## 2. Biodegradable polymers: a green-chemistry extension built on the same compounding base **The company has entered biodegradable polymers under the Deep Bio brand, using renewable plant-based materials that break down into carbon dioxide and water - a new product line that leans on its existing compounding expertise.** - **Made from renewable agricultural plant elements** - Deep Bio raw material is produced from renewable basic elements found in agricultural plants and degrades with the help of bacteria and microorganisms, offering manufacturers a way to reduce plastic waste without abandoning the plastics processing chain. - **Research partnership with IIT Guwahati** - the company signed an agreement with IIT Guwahati’s government-funded research hub to jointly develop biodegradable plastic formulations, transfer technology on sustainable polymers, and even work on edible coatings for fruits and vegetables. Deep Polymers provides the plant and machinery for this development work. - **A dedicated production site already running** - the company has started a new production site specifically for bio-degradable masterbatch, moving the initiative beyond the lab and into commercial manufacturing. # Group structure and partners **The company sits within a family-controlled network of related plastics entities, with a history of consolidation that has simplified the group structure over time.** - **Promoter family at the centre** - as of FY21, the promoter group held roughly 65% of the equity, with Rameshbhai Patel, Ashaben Patel, Jignesha Patel, and others connected as blood relatives, alongside a corporate promoter entity, Deep Additives Private Limited. - **A merger that reshaped the business** - in FY2021-22, the partnership firm Deep Plast Industries was merged into the company at a value of around ₹45-55 crore, settled partly with equity shares issued to the promoter partners and partly in cash, consolidating operations at the Rakanpur-Santej site. - **Related entities still in orbit** - the company holds a 33.79% stake in Deep Additives Limited and has transactions involving the sale of stores, raw materials, and equipment with both Deep Additives and Deep Masterbatch Limited, though a planned merger of these entities into Deep Polymers was approved by the board in 2021 and does not yet appear completed in subsequent filings. - **No subsidiaries or joint ventures** - the company operates without a subsidiary or joint-venture layer, keeping the structure flat as of the latest filings.
