MC Blue Plastic Board Casting Nylon Sheet MC901
The difference between MC Nylon and ordinary nylon (such as PA6/PA66)
Characteristics MC Nylon (Cast Nylon) Ordinary nylon (such as PA6/PA66)
Processing Method In-situ polymerization of monomers (casting and curing in a mold) Melt extrusion/injection molding
Molecular structural integrity Higher, no melt shear degradation, more uniform
molecular weight distribution May degrade or orient due to processing temperature and shear
Crystallinity Higher (up to 50% or more) Relatively low
Mechanical strength Higher, especially tensile, compressive, and impact resistance Good, but slightly inferior to MC nylon
Wear resistance Better Good
Self-lubricating properties Better Average
Dimensional stability Better, less internal stress May generate more internal stress due to processing
Processing flexibility Can only produce simple shapes, suitable for thick plates/large parts Can be complexly molded, suitable for precision small parts
Cost and process complexity Relatively specialized process, requiring high equipment
requirements, suitable for mass customization of thick plates Low cost, suitable for large-scale standardized production
Product Advantages
Ultra-High Wear Resistance + Self-Lubrication
MC nylon sheet's extremely low coefficient of friction (0.15-0.3) and exceptional wear resistance (wear loss <0.08 cm³/1.61 km) make it the preferred choice for high-friction, low-speed components in heavy industries such as mining, metallurgy, and power generation. For example:
Mining Machinery: Conveyor rollers, scraper sprocket liners, and crusher bearing seats (replacing steel components) reduce friction losses by over 80% (with a lifespan 5-10 times that of steel) and eliminate the need for regular lubrication and maintenance (reducing downtime).
Heavy Equipment Bearings: Self-lubricating bearings (20-50 mm thick) for large reducers and roller liners for rolling mills. They have a load capacity of hundreds of tons (compressive strength >150 MPa) and their self-lubricating properties prevent seizure, making them suitable for harsh, dusty environments.
General-purpose mechanical guide rails: Machine tool table guide rails, hydraulic cylinder piston rod guide sleeves (MC nylon sliders), with low friction (improving equipment operating accuracy) and uniform wear (extending overall equipment life).
High load-bearing capacity + dimensional stability
Compared to traditional metals (such as cast iron and steel), casting nylon sheet offers similar load-bearing capacity (compressive strength is nearly 1/3 that of cast iron, but the weight is only 1/7-1/5). It also offers corrosion resistance, low noise, and ease of processing, making it a suitable metal replacement for weight-sensitive or corrosion-prone applications. For example:
Chemical equipment: Corrosion-resistant pump impellers, valve seals, and reactor agitators (replacing stainless steel). They resist corrosion from weak acid/alkaline solutions (such as dilute sulfuric acid and sodium hydroxide <5%) while remaining lightweight (reducing equipment energy consumption).
Construction machinery: Wear-resistant plates (30-80mm thick) for tower crane pulley bushings and concrete mixers. They can carry heavy loads (such as hook loads) while avoiding direct metal-to-metal friction (reducing noise and wear).
Automotive Parts (Special Applications): Non-load-bearing but high-wear components (such as under-hood rails) can be used as metal replacements to reduce noise and vibration (NVH optimization).
Easy Processing + Low Cost
MC 901 sheet can be directly molded into oversized (thickness > 100mm) and complex (with inserts/through-holes) components through casting. This eliminates the mold limitations of injection molding/extrusion nylon, and the processing cost is lower than metal processing (for example, tool life for milling MC nylon is 30%-50% longer than for milling steel).
Customized Industrial Parts: Large gears (module > 5), coupling flanges, and bearing retainers (molded in one step through casting, resulting in a dense, defect-free internal structure) with a short processing cycle (from design to finished product in less than 2 weeks).
Waste Recycling: Processing waste (such as turning chips and scraps) can be crushed and recast, achieving a comprehensive material utilization rate > 90%, reducing production costs.
Maintenance-free design: The self-lubricating property enables the equipment to operate in an oil-free environment (such as clean rooms in food factories and pharmaceutical factories), reducing the risk of lubricating oil contamination (in compliance with hygiene standards).
