Tarnoprop (PP) – polypropylene


Tarnoprop H (H-PP) - Polypropylene homopolymer

A partially crystalline polymer. Density: 0.91 g/cm3. Melting point: approximately 160°C. Hard, resistant to tension cracks. Resistant to low temperatures. Below 0°C it shows a significant decrease in hardness. Polypropylene (PP) ages under the influence of light, UV radiation and temperature. It has very good chemical resistance (not resistant to aromatic and chlorinated hydrocarbons). Glass fibre reinforced grades are characterized by high stiffness and dimensional stability. Shows no hygroscopic properties and therefore does not need to be dried before processing.

Tarnoprop C (PP-C) - polypropylene copolymer

A partially crystalline polymer. Density: 0.91 g/cm3. Hard, resistant to tension cracks. Resistant to low temperatures. Glass fibre reinforced grades are characterized by high stiffness and dimensional stability. Very good chemical resistance (not resistant to the action of aromatic and chlorinated hydrocarbons). Shows no hygroscopic properties and therefore does not need to be dried before processing.
