CHEMICAL NAME Polypropylene
GRADE Co-polymer
NORMAL STATE Solid = Rolls or plates
STANDARD COLOURS White
ODOUR Imperceptible
SPECIFIC WEIGHT 0,91
REACTION WITH OTHER CHEMCAL PRODUCTS Information available upon request
STABILITY Ductile at 146 ºC. Does not break down when subject to temperatures below 280ºC.
FIRE RATING As with most organic polymers, PP will burn slowly and form drops but is unlikely to catch fire and, while combustible, is not flammable. The main combustion products are carbon dioxide, carbon monoxide, water and carbon. In the event of fire, any fire extinguisher can be used. (DIN 4102= B2) (DIN EN 13501-1 = E-d2)
CORROSION Non-corrosive
TOXICITY Standard PP is advisable for use in contact with food.
