The scientific activity performed in this department concerns mainly polyolefines, but other polymers are studied also.
Research work is carried out, based on contracts with the Romanian Ministry of Education and Research and with independent companies.


Some inventions elaborated in this department have been applied in the Production Plant.
The following problems have been studied in this department:

Technologies for obtaining new polymers and copolymers based on ethylene (linear low density polyethylene, ethylene-maleic diester copolymer, ethylene-vinyl acetate copolymer, modified polyethylene with polar groups);

Obtaining of new blends and composites with improved characteristics, based on polyolefines and elastomers, with inorganic fillers, polyolefinic composites with UV stabilizers and composites with fireproofing agents;

Testing new additives for polyolefines;

Obtaining new ranges of polyolefines such as: antistatic polyethylene, expandable polyethylene photo-biodegradable polyethylene, photocrosslinked polyethylene, fire-resistant polyethylene;

Obtaining films with target-properties for special uses: agriculture (thermal film), constructions, hydro-insulation, military;

Studies of thermo- and photo-oxidative stabilization and aging phenomenon of polyolefines;

Studies about obtaining and using natural antioxidants for polymers, such as vitamin E, flavonoids, Alga Spirulina.


The Polymers and Intermediaries Department also performs specific analyses for interested customers (especially polyolefines processing companies) such as:

Density

Melt Flow Index

Tensile Properties

Dart Impact Resistance

Environmental Stress Crack Resistance for polyolefines,

according to ASTM, ISO and STAS regulations.
