REPOL (POLYPROPYLENE)

REPOL - B220MN (IMPACT COPOLYMER)

Product Description and Applications

REPOL Polypropylene B220MN is manufactured using Unipol PP process which combines the production efficiency of gas phase fluidized bed reactor technology with the high activity and stereo specificity of the SHAC catalyst system.

REPOL B220MN is recommended for use in Injection Moulding processes where high flow and medium impact strength is required. It is an ideal material for rigid packing, automotive components, housewares and appliances parts. Repol B022MN contains nucleating agent.

Features

Repol B220MN is designed to provide

Excellent flow characteristics
Short moulding cycle
Consistent processability
Good stiffness-impact balance
Good surface gloss
