High flow for thin walls, controlled and predictable
CM500LN is a controlled-rheology impact copolymer with an extremely high 50 MFR: it fills complex, thin-walled molds fast for short cycles, while keeping a usable balance of stiffness and impact. It is made with a non-phthalate catalyst and ships with molding guidance.

About this product
PP CM500LN Natural is a controlled-rheology, medium-impact polypropylene copolymer with an extremely high 50 MFR — engineered for high-speed, thin-wall injection molding, with a non-phthalate catalyst and a usable balance of stiffness and impact. Based on the COPYLENE® CM500LN grade.
Why engineers choose PP CM500LN
A very high-flow PP that fills thin walls fast and processes predictably.
Extremely high flow (50 MFR)
Fills complex, thin-walled molds quickly and efficiently, cutting cycle times on high-speed parts.
Controlled rheology
Consistent, predictable melt behavior shot to shot, so thin-wall parts stay repeatable across a run.
Stiffness & impact balance
Keeps structural integrity and toughness (110 J/m notched IZOD) despite its very high flow.
Non-phthalate catalyst
Manufactured without phthalates, a useful consideration for consumer and food-related markets.
How we supply it
Genuine resin, ready to mold, with the parameters your process engineer needs.
Step 01
Sourced & lot-traced
Genuine COPYLENE CM500LN PP, packed in sealed 2 lb units and shipped from US stock. Minimum order 5 units.
Step 02
Mold ready

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
Do I need to dry PP CM500LN before molding?
Not usually. Polypropylene absorbs very little moisture, so PP CM500LN does not typically require drying. Store the sealed units in a cool, dry place and keep them closed until use. A short dry only helps if the pellets have been exposed to humidity for a long time.
What makes CM500LN good for thin-wall molding?
CM500LN has an extremely high 50 MFR, so the melt flows easily into thin, complex sections and long flow paths that lower-flow grades struggle to fill. Its controlled rheology also keeps shots predictable, which matters for consistent thin-wall containers and detailed parts at short cycle times.
What melt and mold temperatures does PP CM500LN need?
PP CM500LN molds at a melt temperature of 190–230°C (374–446°F) with a mold temperature of 40–80°C (104–176°F). Its very high flow means it fills easily at the lower end of that range. These are starting points — a materials engineer can help tune them for your part.
What does non-phthalate catalyst mean?
It means CM500LN is manufactured without phthalate compounds in its catalyst system, which some consumer and food-related markets prefer or require. It is a formulation consideration worth noting during material selection; a materials engineer can confirm whether it fits your compliance needs.
What is PP CM500LN used for?
PP CM500LN suits thin-wall containers, food storage and disposable packaging, housewares, toys and products with detailed features, and technical parts where fast cycling and easy flow are critical. Its high flow and controlled rheology make it a natural fit for high-speed molding.
How is PP CM500LN packaged and what is the minimum order?
PP CM500LN ships in sealed 2 lb units, and the minimum order is 5 units (10 lbs total). Larger volumes and official purchase orders are welcome — contact us for volume pricing. Material ships from US stock, typically within 1–2 business days.
Will PP CM500LN run on the APSX-PIM desktop molder?
Yes. PP CM500LN is formulated for desktop and standard injection molding, including the APSX-PIM. Its very high flow makes it one of the easiest grades to fill on smaller machines. Our team can confirm shot size and parameters for your specific mold.
