Plastic sheets are widely used semi-finished products in industrial manufacturing, known for their versatility, chemical resistance, and ease of fabrication. They serve as the base materials for machining gaskets, seals, wear parts, structural components, and insulation parts.
Depending on the polymer type and production method—such as extrusion, molding, or skiving—plastic sheets can be tailored to meet specific performance requirements involving temperature, mechanical stress, chemical exposure, or dimensional stability.
| Material | Key Characteristics | Typical Applications |
|---|---|---|
| PTFE (Polytetrafluoroethylene) | Exceptional chemical resistance, non-stick, wide service temperature range (–200 °C to +260 °C), low friction coefficient | Chemical-resistant gaskets, linings, electrical insulation, and sliding bearings |
| PVC (Polyvinyl Chloride) | Rigid, corrosion-resistant, cost-effective, easy to weld and fabricate | Tanks, ducts, panels, cladding, and general industrial applications |
| PP (Polypropylene) | Lightweight, tough, excellent chemical and fatigue resistance, weldable | Chemical tanks, laboratory equipment, linings, and cutting boards |
| PE (Polyethylene – HDPE/LDPE/UHMWPE) | Tough, impact- and wear-resistant, excellent moisture barrier | Linings, wear strips, food-grade cutting boards, and mechanical components |
| ABS (Acrylonitrile Butadiene Styrene) | Strong, impact-resistant, easily machined or thermoformed | Enclosures, panels, machine housings, automotive, and prototype parts |
| PC (Polycarbonate) | High impact strength, transparent, heat-resistant, and good dimensional stability | Machine guards, glazing, safety shields, and instrument covers |
| PMMA (Acrylic / Plexiglass) | Optical clarity, UV and weather resistance, lightweight | Display panels, signage, lighting diffusers, and glazing |
| Nylon (PA6 / PA66) | High mechanical strength, wear, and fatigue resistance | Bearings, bushings, gears, spacers, and structural parts |
| POM (Acetal / Delrin) | High stiffness, low friction, excellent dimensional stability | Precision gears, valve seats, seals, and mechanical components |
| PEEK (Polyetheretherketone) | High-performance engineering plastic with exceptional thermal (up to +250 °C continuous), mechanical, and chemical resistance; excellent dimensional stability and wear performance | Aerospace, oil & gas, semiconductor, and chemical industries—used for seals, bearings, valves, and high-load structural parts |
Note: PEEK is one of the most advanced engineering plastics available, offering a unique combination of strength, stiffness, and chemical inertness suitable for replacing metals in high-performance environments.
Plastic sheets are manufactured in a wide range of sizes and thicknesses depending on the material and forming process:
| Standard Size (mm) | Equivalent (inch) | Typical Thickness Range |
|---|---|---|
| 1000 × 1000 | 39" × 39" | 0.3 – 100 mm |
| 1200 × 2400 | 48" × 96" | 0.5 – 50 mm |
| 1500 × 3000 | 60" × 120" | 1 – 100 mm |
| 2000 × 1000 | 78" × 39" | 1 – 100 mm |
PTFE and PEEK sheets are generally produced by molding or skiving due to their processing characteristics, while materials such as PVC, PP, and PE are typically extruded.
Plastic sheets are used across a broad range of industries and functions, including:
Sealing and Gaskets: PTFE, PEEK, and POM for high-performance sealing in chemical and mechanical systems.
Corrosion Resistance: PVC and PP for tanks, ducts, and chemical containment.
Wear and Structural Components: Nylon, UHMWPE, and PEEK for bushings, bearings, and machine parts.
Electrical and Thermal Insulation: PTFE, PEEK, and PC for insulation, spacers, and covers.
Display and Architectural Applications: PMMA and PC for transparent or decorative panels.
Food and Pharmaceutical Processing: UHMWPE, PP, and PTFE for contact parts, cutting boards, and lining materials.
