The department is engaged in studying and testing of plastics and polymeric composites and in fluoroplastic technology. It is ranked among the leading institutions developing and processing fluoroplastics in the Czech Republic. METALOFLON® self-lubricating bearing foil, the most widespread Czech invention in automotive industry, was developed here. The department has implemented a quality management system according to CSN EN ISO 9001 certified by LL-C (Certification) Czech Republic s.r.o
Polymers technology:
- Tests of impact and notch toughness by Charpy, Izod methods (0.5 - 4 J) at laboratory temperature
- Creep tests at constant tensile stress at laboratory temperature and bending stress in a three-point configuration over a temperature range (23-80 ° C).
- Light microscopy, density measurement, determination of fillers (combustion test - determination of ash content), gravimetric determination of moisture content.
- Determination of Shore A, Shore D hardness and ball indentation method according to ČSN EN ISO 2039-1.
- Determination of tensile properties of plastics at laboratory temperature - modulus of elasticity, stress and deformation according to ČSN EN ISO 527.
- Thermal analysis in the temperature range of -85 ° C to 550 ° C by Differential Scanning Calorimetry (DSC) - determination of melting point and glass transition, specific melting heat, crystallinity, annealing or curing control etc.
