POLYMER SOURCING

PP Injection Molding Grade Supplier

Injection grade selection starts from MFI and the stiffness–impact balance: low-MFI impact copolymers for crates and appliance parts, high-MFI grades for thin-wall packaging, random copolymers for clear housewares.

Material properties to specify
MFI from about 2 to 90 g/10 min
Homopolymer, impact or random copolymer
Flexural modulus, notched impact and HDT
Typical applications
Appliance housings and washing-machine partsThin-wall food containers and capsCrates, furniture, housewares and automotive parts
