When your application demands performance above 150°C, the field of viable engineering plastics narrows quickly. PPS GF40 (glass-filled polyphenylene sulfide) and PEEK are the two most commonly considered materials. This comparison examines their relative strengths to help you make the right choice.
PEEK is one of the most machinable high-performance plastics, but its unique thermal and mechanical properties require specific machining strategies. This guide covers everything from tool selection to stress relief, helping machinists achieve precision tolerances and excellent surface finishes on PEEK components.
Electronics manufacturing requires strict ESD (electrostatic discharge) control to protect sensitive components from damage. Selecting the right ESD materials for EPA (Electrostatic Protected Area) zones is critical for maintaining yield, reducing field failures, and meeting quality standards like ANSI/ESD S20.20 and IEC 61340-5-1.
The semiconductor industry is the single largest consumer of high-performance engineering plastics per unit of output. From wafer fabrication to packaging and test, engineering plastics are essential components in virtually every piece of semiconductor manufacturing equipment. This guide examines the materials, applications, and trends driving this critical market.
PEEK and PEI (ULTEM) are two of the most respected high-performance engineering plastics. Both offer inherent flame retardancy and excellent mechanical properties, but they serve different application sweet spots. This comparison helps engineers determine which material is the right choice for their specific requirements.
PTFE (polytetrafluoroethylene), widely known by the DuPont brand name Teflon, is the most chemically inert and lowest-friction engineering plastic available. PTFE sheets are used in applications requiring ultimate chemical resistance, extreme temperature performance, or non-stick surfaces where no other material can survive.
PA66 (polyamide 66, commonly called nylon 66) is one of the most widely used engineering plastics globally. Known for its excellent toughness, high impact strength, and good temperature resistance, PA66 sheets are the go-to material for applications requiring durability at moderate temperatures and a competitive price point.
The global transition to renewable energy is driving unprecedented demand for engineering plastics in electric vehicle (EV) batteries, solar panels, and wind turbine components. Engineering plastics offer the electrical insulation, thermal management, chemical resistance, and mechanical strength that these clean energy technologies require.
PPS GF40 — polyphenylene sulfide reinforced with 40% glass fibre — is a high-performance engineering plastic that bridges the gap between standard engineering plastics and premium materials like PEEK. Offering excellent dimensional stability, chemical resistance, and structural performance at temperatures up to 200°C, PPS GF40 is a cost-effective solution for demanding applications.
PEI (polyetherimide), commonly known by the brand name ULTEM, is an amorphous high-performance engineering plastic that delivers a unique combination of strength, flame retardancy, and thermal stability. PEI sheets are widely used in aerospace, medical, and industrial applications where fire safety and structural performance are both required.
