SEMI-CONDUCTOR & POWER

Gharda Plastics’ advanced ultra high-performance polymers—including PEK (Polyetherketone), PEKK (Polyetherketoneketone), and PEI (Polyetherimide)—are critical materials serving both the semiconductor and diverse energy industries, delivering exceptional properties, key applications, and significant advantages.
In the semiconductor industry, PEK and PEKK provide outstanding dimensional stability, excellent wear and chemical resistance, and high-temperature tolerance, essential for precise and durable components such as wafer handling systems, processing vessels, parts carriers, and IC test equipment sockets. These polymers enable tight tolerance machining and exhibit very low moisture absorption, supporting the industry’s demand for smaller, high-frequency IC packages that require materials capable of replacing metals while maintaining performance under thermal and mechanical stresses.
In the energy industry—including nuclear, wind, thermal, and other alternative energy sectors—these polymers deliver unmatched thermal stability, mechanical strength, chemical resistance, and electrical insulation. For example: PEK exhibits superior resistance to creep and deformation under load at elevated temperatures and outstanding electrical properties, making it suitable for components in harsh environments such as electrical connectors and downhole equipment in oil and gas. PEKK shares similar high-performance traits with added stiffness and strength, applicable in structural parts exposed to extreme thermal and chemical stress. PEI offers excellent high-temperature resistance, dielectric properties, and energy storage potential. Recent advances in PEI-based multilayer nanocomposites demonstrate ultra-high energy storage density and efficiency with stable performance up to 150°C, making it highly promising for energy electronic circuits, pulse power systems, and hybrid vehicles. PEI is also notable for its radiation resistance and fire safety, essential in nuclear power applications.

Key Properties Across PEK, PEKK, and PEI:
High strength-to-weight ratio, often comparable or superior to metals, but lighter
Long-term thermal stability
Excellent chemical and wear resistance extends component lifetimes
Low moisture absorption ensures dimensional stability and reliability under harsh conditions
Electrical insulation is critical for power and semiconductor components
Good machinability for tight tolerance and complex parts
Self-lubrication properties reduce maintenance needs for moving components
Radiation and fire resistance, especially important in nuclear and safety-critical energy systems

Together, PEK, PEKK, and PEI polymers from Gharda Plastics form a robust portfolio that meets the evolving demands of high-technology sectors by replacing heavier metals with lightweight, durable, and reliable plastics. Their specific advantages support innovation in semiconductor manufacturing and safer, more efficient, and sustainable energy technologies.
