PP Application Grade

PP Injection Molding Grade

PP injection grades include homopolymer, random copolymer and impact copolymer options. The correct choice depends on flow, stiffness, impact, transparency and service temperature.

Typical Applications

Housewares

Containers, furniture parts and household products selected for flow, stiffness and appearance.

Appliance Components

Housings and components requiring dimensional consistency and suitable heat performance.

Automotive Parts

Interior and technical parts requiring impact, stiffness, UV or filled compounds.

Industrial Moldings

Crates, closures and molded products selected according to load and cycle targets.

Grade Selection Factors

The following factors are application references, not guaranteed specifications. Final selection must be confirmed using the current producer TDS, COA and customer requirements.

Selection ItemWhat to Confirm
Polymer type Choose homopolymer, random copolymer or impact copolymer according to the application.
Melt flow Match wall thickness, flow length, gate and cycle requirements.
Impact and stiffness Define service temperature and mechanical target.
Filled or modified grade Confirm talc, glass fiber, flame-retardant or other modification needs.

Information Needed for Quotation

Current grade, PP type, part application, wall thickness, MFI, impact target, color, filler or modifier, quantity and destination port.

Frequently Asked Questions

Which PP type gives the best impact resistance?

Impact copolymer is commonly selected for higher impact needs, but the exact grade depends on temperature and stiffness targets.

Which PP type is used for transparent parts?

Random copolymer grades may be considered where clarity and sealing are important.

Can you source filled PP compounds?

Availability depends on filler level, performance, color and order quantity.
