PEEK 3D printing enables production of complex, high-performance polymer parts without traditional machining constraints. This guide explores current PEEK additive manufacturing technologies and how they compare to machined PEEK stock shapes.

Surface finish affects friction, wear, aesthetics, cleanliness, and optical properties in machined PEEK, POM, PPS, and PEI parts. This guide covers available surface finish options.

When sourcing ESD (electrostatic discharge) engineering plastics for electronics manufacturing, understanding the testing standards that define “ESD-safe” is critical. This guide explains the primary ESD standards, their testing methods, and how they apply to ESD plastic materials.

PEEK and PPS are two of the most widely used high-temperature engineering plastics, both offering exceptional thermal stability and chemical resistance. However, their performance profiles differ significantly, and choosing between them can affect part performance, longevity, and cost. This guide compares PEEK and PPS across all critical engineering properties.

Understanding minimum order quantities (MOQ) is essential for procurement planning. MOQs vary significantly by material, shape, dimensions, and manufacturer. This guide covers typical MOQ ranges for engineering plastics and strategies to work within or around these constraints.

A Material Safety Data Sheet (MSDS), now commonly called Safety Data Sheet (SDS), is a critical compliance document for any engineering plastic material. Whether you’re sourcing PEEK, POM, PPS, or PEI, understanding SDS requirements ensures regulatory compliance, workplace safety, and smooth customs clearance.

Color may seem like a cosmetic detail, but in engineering plastics, color choice affects material properties, cost, availability, and regulatory compliance. This guide covers the color options available for PEEK, POM, PPS, PEI, and PA66 — and how to choose the right color for your application.

Unfilled PEEK is an outstanding engineering plastic, but for demanding applications, filled PEEK grades offer enhanced mechanical, thermal, or tribological properties. This guide covers the three most common PEEK filled grades — carbon-filled, glass-filled, and PTFE-filled — helping engineers select the optimal grade for their application.

A material datasheet is the primary technical document for evaluating engineering plastics. However, datasheets can be dense with information, and not all properties are equally relevant for every application. This guide helps engineers and procurement professionals identify the critical properties when reading datasheets for PEEK, POM, PPS, PEI, and PA66.

China’s engineering plastic manufacturing sector has evolved dramatically over the past decade. Today, Chinese manufacturers produce high-quality PEEK, POM, PPS, PEI, and PA66 stock shapes that meet international standards at competitive prices. This guide highlights the top 10 manufacturers shaping the industry in 2026.
