Materials

Engineered Plastics We Machine

At Lehigh Valley Plastics, we machine a wide range of engineered plastics used in wear, load-bearing, and high-performance applications. From nylon and UHMW for heavy equipment to PEEK and PTFE for semiconductor environments, we help customers select the right material based on performance, cost, and application requirements.

Our focus is simple: machined parts, to print, in tolerance, and delivered on time.

Engineered Plastics We Work With

Acetal (POM / Delrin®)
Strong, dimensionally stable material ideal for precision machined components and tight-tolerance parts.
Nylon (PA – Cast & Extruded)
High-strength, wear-resistant plastic commonly used for sheaves, gears, and load-bearing components.
Nylatron® (Filled Nylon Grades)
Enhanced nylon with improved wear resistance and load capacity for demanding applications.
UHMW-PE
Ultra-low friction material used for wear strips, guides, and conveyor components.
HDPE (High Density Polyethylene)
Lightweight, moisture-resistant material used for cutting boards, tank components, and corrosion-resistant parts.
Polycarbonate (PC)
Impact-resistant material used in guards, covers, and structural components requiring toughness.
Acrylic (PMMA)
Clear, rigid material ideal for visual components, displays, and applications requiring optical clarity.
PVC (Polyvinyl Chloride)
Cost-effective material with good chemical resistance for industrial and corrosion-resistant applications.
CPVC (Chlorinated PVC)
Improved temperature and chemical resistance compared to standard PVC.
Polypropylene (PP)
Lightweight, chemical-resistant material used in tanks, fixtures, and processing components.
PET / PET-P
Strong, low-moisture absorption material ideal for precision parts and food processing applications.
PEEK (Polyetheretherketone)
High-performance plastic for extreme temperatures, chemical resistance, and critical environments.
PPS (Polyphenylene Sulfide)
Excellent chemical resistance and dimensional stability in high-temperature applications.
PEI (Polyetherimide / Ultem™)
High-strength, high-temperature material often used in aerospace and medical applications.
PTFE (Teflon®)
Low-friction, chemically inert material used for seals, bearings, and non-stick applications.
Fluoropolymers (General Family)
Includes PTFE, PVDF, and others designed for aggressive chemical environments.
PVDF (Kynar®)
High-purity, chemical-resistant material commonly used in semiconductor and fluid handling systems.
PAI (Torlon®)
Extremely high-performance plastic with excellent wear resistance and high load capability.
Polyimide (PI)
Advanced material designed for extreme heat and high-performance applications.
PSU / PPSU (Radel®)
Tough, high-temperature plastics used in medical and food-grade applications.
PPO (Noryl®)
Stable, low-moisture material used in electrical and structural applications.
Polyurethane (PU)
Flexible, wear-resistant material used for impact and abrasion applications.
