Unfilled PEEK Pellets 880G for Injection

Name: Unfilled PEEK Pellets 880G for Injection
Brand: PRES
SKU: 510884607
Rating: 5.0 (14 reviews)

PEEK 880G is our Enhanced Flow unfilled PEEK pellets (MFR 20 g/10min, ISO 1133), offering easier mold filling for thin-walled or complex injection parts while retaining the inherent toughness of virgin PEEK. Compared with high-viscosity PEEK 990G, 880G provides lower melt viscosity; vs. ultra-high-flow grades it has higher molecular weight and better fatigue resistance. Download TDS and selection guide.

PEEK pellets 880G Product Description

	Enhanced Flow
	✅MFI is 20g/10min ,ISO1133,380°C 5kg ✅The molecular weight of PEEK 880G is at a moderate level (MFR 20 g/10min, ISO 1133), between high viscosity 990G and ultra-high flow grades.
	Balanced Processability & Toughness
	✅Compared to ultra-high flow PEEK resin, 880G has a higher molecular weight, therefore it has better toughness and fatigue resistance, making it more suitable for applications with certain dynamic loads. ✅Compared to high viscosity PEEK 990G: 880G, the melt viscosity is lower, making it easier to fill molds with thin-walled, complex structures, or long flow channels, and suitable for injection molding precision PEEK components.

| PEEK pellets 880G Application

PEEK 880G is an Enhanced Flow unfilled resin pellets with excellent chemical resistance, high-temperature stability and inherent toughness. It is specifically developed for injection molding of precision PEEK components.

Thanks to its balanced molecular weight, 880G combines good mold filling capability with retained toughness, making it suitable for parts requiring both dimensional accuracy and mechanical reliability under dynamic or sterilizable conditions.

PEEK 880G is widely used in electronics, semiconductor, medical devices, analytical instruments, and automotive systems where tight tolerances, chemical resistance and high heat resistance are required.

Typical injection molded PEEK 880G components include:

PEEK screw molded from Unfilled PEEK pellets

Unfilled PEEK have better toughness and chmical purity than filled PEEK grade.

Screw made of food grade unfilled PEEK pellets can replace metal,use in device which need to contact with food.

Unfilled PEEK also has better chemical resistance & UV resistance,the components can work in corrosion and Strong ultraviolet rays condition

PEEK sealing ring made of unfilled PEEK pellets

Unfilled PEEK pellets provide a low coefficient of thermal expansion (CLTE), which—when combined with high-precision injection molds—yields superior surface flatness and excellent sealing performance in finished parts.

With a continuous use temperature of 260°C (UL 746) and inherent resistance to acids, bases, and high-pressure steam, virgin PEEK resin outperforms metal in aggressive thermal-chemical conditions, permanently resolving metal’s susceptibility to corrosion and degradation.
