PLASTICS IN MEDICAL, DENTAL & PHARMACY
- In health care industry, products need to be of purest quality with respect to hygiene & sterility.
- PE, PU, PET, TPE are used extensively in this field.
- Dentists are using acrylics as bone cement and as dentures.
PLASTICS IN CIVIL ENGINEERING & ARCHITECTURE
Drainage System
-Plastic pipes are used by contractors: based on cost, ease of installation and availability.
- Commonly plastic drainage pipes are made with PVC and HDPE.
Rain Water Harvesting
- Rainwater harvesting is a technology used for collecting and storing rainwater from rooftops, the land surface or rock catchments using simple techniques such as jars and pots as well as more complex techniques such as underground check dams.
- Rain collection barrels are made up of HDPE and piping involved in this system is met by PVC.
Building and Civil construction
- Construction is the second largest market after packaging.
- Plastics makes a significant contribution to long-life applications such as pipes, insulation, windows, cables and floor coverings.
- Plastics are used very effectively for various structural and non-structural applications in construction, because they provide long-lasting and easy solutions.
Roads, Pavements & Geo-membranes
- Plastics are commonly used to mark cross marks(pedestrian crossing), stop lanes & traffic guidance such as turn lanes, HOV(High Occupancy Vehicle) lanes, train crossings, taxi lanes & bus lanes.
