Amines & Plasticizers Ltd is a speciality chemicals maker whose products are the invisible workhorses inside oil refineries, pharmaceutical plants, textile mills, and electronics factories - the amines and solvents that strip out impurities, catalyse reactions, and make fibres possible. Founded in 1973 as a first-generation venture by Hemant Kumar Ruia, it was the first Indian company to indigenously develop methyl diethanolamine (MDEA), a critical gas-treating solvent, and has since grown into one of the world’s largest producers of N-methyl morpholine oxide (NMMO), serving customers across more than 85 countries. The recurring approach is to build proprietary, hard-to-copy chemical know-how in-house - for every product except ethanolamines, the technology comes from its own R&D - and then sell those molecules globally into industries where switching suppliers is slow and expensive.
Business segments
Four chemical engines built on a single manufacturing backbone - a gas-treating franchise that cleans the world’s refineries, an ethanolamine business that dominates its home market, a morpholine platform that enables greener textiles, and a specialty ethoxylates engine feeding everything from cosmetics to electronics - plus a small oilfield-and-engineering division that rounds out the portfolio.
1. Gas treating chemicals and specialty solvents: the refinery’s cleaning crew
APL makes the solvents that strip carbon dioxide and hydrogen sulphide out of gas streams in refineries, fertiliser plants, and hydrogen production units - and it was the first Indian company to do so with its own technology.
- The cornerstone molecule - MDEA is the base solvent for removing CO₂ and H₂S from process gas, and APL’s indigenously developed version anchors a family of formulated blends sold under the Aminosol brand.
- Custom blends for specific customers - the company has developed tailor-made solvent formulations for over 25 domestic and international clients, including demulsifiers matched to country-specific crude profiles and carbon-capture formulations for flue gas and cement plants.
- Not just chemicals, but the engineering to use them - APL sells analytical and process engineering services alongside its solvents, including amine analysis, process simulation software, operator training, and even physical Amine Reclamation Units that extend solvent life inside refineries.
- Hydrogen and carbon capture are the next frontier - its formulated MDEA already works across Brown, Grey, Blue, and Turquoise hydrogen production, and the company has tied up with a leading Japanese multinational to manufacture new carbon-capture solvents.
2. Alkanolamines and alkyl alkanolamines: the domestic champion
APL supplies roughly 70% of India’s ethanolamine demand - the nitrogen-containing alcohols that go into everything from cement additives and water-treatment chemicals to pharmaceutical raw materials.
- A commanding home-market position - the company holds a 75-80% domestic market share in ethanolamines and caters to approximately 70% of total Indian demand for ethanolamines and alkyl alkanolamines.
- Products that touch construction and medicine - two propylene-oxide-based alkyl alkanolamines are used as cement grinding aids in infrastructure, while another product gained prominence as a raw material for COVID-19 treatment drugs.
- Green-chemistry credentials in paints - two products developed by the company are used in water-borne paints and automobile coatings, replacing environmentally unfriendly solvents.
- The building blocks for multiple industries - these molecules feed into oil refining, petrochemicals, pharmaceuticals, agrochemicals, and textiles, making them a broad-spectrum intermediate.
3. Morpholine and derivatives: the green-textile enabler
APL is among the world’s largest producers of NMMO, the solvent that makes Lyocell fibre possible - a cleaner alternative to viscose that has reshaped the textile industry.
- The molecule behind a fibre revolution - NMMO (N-Methylmorpholine N-oxide) is an environment-friendly solvent that dissolves wood pulp to spin Lyocell fibre, replacing the polluting viscose process without environmental harm.
- Global scale in a niche - the company is recognised among the world’s leading manufacturers of morpholine and its derivatives, and ranks among the largest producers of NMMO globally.
- Pharmaceutical linkages - one morpholine derivative serves as a key raw material for an immunosuppressant drug, giving the engine exposure to high-value pharma supply chains.
- A natural hedge against raw-material risk - the company imports morpholine as a raw material but exports morpholine derivatives, so foreign-exchange exposure is largely offset by the export revenue stream.
4. EO/PO-based specialty products: the formulation toolkit
Using ethylene oxide and propylene oxide as building blocks, APL makes ethoxylates, polyols, and copolymers that become surfactants, polyurethane systems, and performance additives for a widening set of end markets.
- Surfactants and emulsifiers - alcohol ethoxylates, sorbitol ethoxylates, and fatty alcohol propoxylates feed the growing surfactants field, while neem-based agrochemical emulsifiers contribute to green chemistry.
- Polyols for polyurethanes - glycerol polyol and PPG 4000 are the precursors for polyurethane systems used in foams, coatings, and elastomers.
- High-purity grades for demanding applications - demand is rising for high-purity versions of cosmetic ingredients, metal-working fluids, drug intermediates, textile auxiliaries, and electronic chemicals, all of which draw on EO/PO chemistry.
- R&D is expanding the range - the company has commercialised cocoamine-based ethoxylates and glycerin-based propoxylates through in-house R&D, and is designing a range of surfactants based on tridecyl alcohol ethoxylate.
5. Oilfield chemicals, industrial gases, and engineering services: the ancillary workshop
A compact division that supplies hydrogen-sulphide scavengers and corrosion inhibitors to upstream oil and gas, plus dissolved acetylene and custom pressure equipment from a separate site at Khopoli.
- Chemicals for the oil patch - the portfolio includes H₂S scavengers, acid corrosion inhibitors, flow improvers, pour-point depressants, bactericides, and oil-spill dispersants, with products accepted in international markets.
- A small industrial-gas operation - the Khopoli plant manufactures dissolved acetylene with a capacity of 2 lakh cubic metres per year, running at roughly 50% utilisation with a team of eight.
- Heavy fabrication on the side - the engineering services division at the same Khopoli site builds heat exchangers, pressure vessels, and boilers with a capacity of 100 tonnes per month and a team of 80.
- Molecular-sieve distribution - APL represents one of the world’s biggest molecular-sieve producers and is a major distributor in India, supplying drying agents used in industrial gases, fuel ethanol, and polymer processing.
Manufacturing, technology, and R&D infrastructure
Two integrated plants in Maharashtra, 13 reaction chemistries under one roof, and a DSIR-recognised R&D lab that has commercialised 43 new products in five years - this is the shared backbone that makes every segment possible.
- Two sites, one chemistry backbone - the main Turbhe plant in Navi Mumbai sits on 18.11 acres with 32,760 MTPA of installed capacity and runs at 85% utilisation, while the Khopoli site adds another 25.41 acres housing the gases and engineering divisions.
- In-house R&D as the growth engine - the DSIR-recognised lab has commercialised 43 new products over five years, developed import-substitute molecules for electric-vehicle batteries and hydrogen electrolysers, and created custom solvent formulations for more than 25 customers.
- Self-sufficient engineering - an in-house engineering division handles plant maintenance and equipment upkeep, reducing reliance on outside contractors and keeping costs down.
- Raw-material strategy built around ethylene oxide - the single most important feedstock is ethylene oxide, sourced locally because it is too inflammable to import; the company manages price volatility through commercial negotiation and has invested in its own fleet of EO tanks for safer logistics.
Group structure and partners
A lean structure centred on a single listed entity with one overseas subsidiary in the UAE, a 26% stake in a captive solar-power venture, and technology partnerships with American and Japanese multinationals.
- The UAE subsidiary - wholly owned Amines and Plasticizers FZ-LLC in the Ras Al Khaimah Free Trade Zone trades in the company’s products and those of other manufacturers, giving APL a foothold in Middle Eastern markets.
- Captive solar power - a 26% stake in Radiance MH Sunrise Six Private Limited was taken as a regulatory pre-condition to secure a 2.6 MW ground-mounted solar plant that supplies concessional green power to the company’s operations.
- Global technology tie-ups - the company has memoranda of understanding with leading American and Japanese corporations for customised product development, including a tie-up with a Japanese multinational for manufacturing new carbon-capture solvents.
- Promoter-led governance - the board is chaired by founder Hemant Kumar Ruia (over four decades of experience) alongside his son Yashvardhan Ruia as Executive Director; the company is listed on both BSE and NSE.
