Expanded Polystyrene India

Expanded Polystyrene India

Expanded Polystyrene India –  Expanded Polystyrene (EPS) is a light weight and completely recyclable material that has various applications in packaging and insulation.  EPS can be moulded to virtually any shape, giving unlimited freedom to designers. Here, at K. K. Nag Pvt. Ltd, we cater to a variety of customer sectors that include white goods, FMCG (Fast Moving Consumer Goods), pharmaceuticals, agricultural products, the automobile industry, construction, electronics and fisheries.

Annually, we process approximately 4,500 tonnes of Expanded Polystyrene from our four factories, making us one of the largest EPS shape moulders in India. Our units are spread across the country in Maharashtra (Urse and Ranjangaon), Tamil Nadu (Thiruvallur) and Puducherry and we have more than fifty machines that range from 400 × 600 mm to 1300 × 1700 mm in platen size.  We are proud to say that we are reputed to be the most technically progressive and competent EPS processor in India.

Everything, from conceptualisation to the final product, is handled by our expert in-house team.  This includes prototyping and design, development and manufacture of EPS moulds and the moulded parts.

We were the first Expanded Polystyrene processor in India to receive ISO 9001:2000 certification and have since been certified for ISO 9001:2008, ISO 14001:2004, BS OHSAS 18001:2007 and ISO/TS 16949:2009.  K. K. Nag Pvt. Ltd is also the single source EPS supplier to several renowned national and international brands.

Applications of EPS

Expanded Polystyrene India

EPS is one of the most cost-effective protective packaging materials available and is used all over the world to protect goods from transit damage.  It possesses an extraordinary combination of lightness, rigidity and shock absorption and can be moulded to virtually any shape desired.

EPS is also used widely for low temperature thermal insulation because of its low thermal conductivity and closed cell structure (most other thermal insulation materials have open cell structures which make them vulnerable to moisture penetration).  Because EPS has no taste or odour and does not harbour fungi, it is used extensively in the packaging of pharmaceutical products, such as vaccines, where stringent temperature ranges are required to be maintained.

Expanded Polystyrene is also used to make internal components for the air-conditioning and refrigeration industries.  Earlier, these parts were made by gluing insulation materials on to a metal sheet but they have been now replaced by EPS because it possesses both rigidity and the required insulation properties, and can be moulded in one piece.

Expanded Polystyrene packagings used for packing fruits

EPS is now widely used for the packaging of agricultural products in India and various countries.  Fruits such as grapes, pomegranates, papayas, mangoes and many others, and various types of vegetables, are conveniently packed and stored in EPS containers.  Even in the marine industry, EPS boxes are used extensively to stock fish and other seafood.

Another useful application of EPS is in construction.  Its high thermal insulation makes it an excellent material to use in the construction of walls and ceilings and its high sound absorption makes it the ideal choice for sound-proofing.

Another recent application of EPS is as “Geofoam” in landfills.  This application is made possible because of EPS’s light weight, water resistance, dimensional stability and inert nature.
