Random Copolymer Polypropylene

DESCRIPTION
TIPPLEN R 959 A is a reactor grade random copolymer polypropylene for injection moulding
applications. The product formulated with special nucleating and optical whitener agent with excellent
transparency and gloss. This improved reactor grade has very narrow MWD which provide good
dimensional stability, low warpage, excellent smellodor and organoleptic behaviors. This grade
contains nucleating and antistatic agent.
TIPPLEN R 959 A is suitable for replacement of PVC, PS or PET.
APPLICATIONS
TIPPLEN R 959 A is recommended for injection moulding for the production of household articles,
containers and thin?walled packaging for cosmetics, toiletries, herbs, confectionery, where the higher
gas-permeability is no problem. It is applicable for injection moulding of transparent food containers,
which can use in microwave oven.
TIPPLEN R 959 A is suitable for food contact. The product complies with Food Contact and Toy Safety
Regulations.
