HDPE Sheets, LDPE Sheets

A. hdpe film sheet:
hdpe films mostly used in land fill applications, which protect the environment from the contamination produced by percolation of rainwater through the waste. A capping system will protect the landfill from further water infiltration.
due to excellent chemical, physical, biological properties hdpe sheets are used for ground water protection and water engineering including the sealing of waste disposal sites, industrial lagoons and reservoirs.
advantages of hdpe films:
hdpe have high tear resistance, ozone, oxidation, weathering resistance, low coefficient of thermal expansion, flexibility, chemical resistance, proof resistance, low temperature resistance, friction resistance, high erosion resistance stating and migration resistance.
applications:
* landfill for waste
* masking of concrete structure at port
* storage of agriculturalindustrial slurries
* salt spans
* protection from pollution
* fire fighting lagoons
* lining canals
* dams, reservoirs.
b. ldpe film sheet:
low density polyethylene (ldpe) sheets are extensively used for protection of liquid contamination, agricultural, industry, industrial projects. Ldpe film acts as a perfect line to prevent foreign material entering through ground water source as well as prevent seepage loss in water conservation projects.
other applications:
* agriculture
* lining of canal, reservoir, ponds
* lining of industrial effluent plant
* tunnels
* packaging and wrapping
* water roofing for terrace gardens
* for protection of food grains, fertilizers, cotton, chemicals, cement, constructions and power plants
* concrete road and bridge
* steel plants etc.
properties of ldpe:
* ldpe film has excellent mechanical properties.
* saves water seepage upto 60% of total quality of water available.
* it has a very low moisturevapour transmission rate.
* very good resistance against chemical and unaffected by bacterial or fungal growth.
* very good resistance against ozone, oxidation, weather & water because polyethylene has a long chain of hydrocarbon which gives above properties.
