Pyongyang, November 1 (KCNA) — Scientists of the Institute of Agricultural Science in the DPRK developed high-quality functional nano plastic sheet.
It is 1.2 times stronger than ordinary plastic sheet in tensile strength, 2 times higher in elongation percentage and 1.5-2 times longer in serviceable life.
The production process of functional nano plastic sheet was set up in a short span of time.
The functional nano plastic sheet has been introduced into different units to prove effective in raising temperature of rice-seedling beds and germination rate, while enjoying great demand for its high quality and low cost.
It was highly appreciated at the national nano sci-tech exhibition-2017 held some days ago.
