Special color of nylon (containing oil）

MC Nylon (Monomer Casting Nylon, also known as cast nylon) is a high-performance engineering plastic that is directly cast through anionic polymerization reaction. The following is a detailed description of its products:

1. Material properties

High strength and wear resistance: The mechanical strength of MC nylon is higher than that of ordinary nylon 6, and it has excellent wear resistance, making it suitable for high-load and friction environments.

Self-lubricating property: Low coefficient of friction, no additional lubrication required, suitable for oil-free working conditions.

Chemical resistance: Resistant to oil, weak acids, alkalis and organic solvents, but not resistant to strong acids and strong oxidants.

Temperature resistance range: -40℃ to +120℃ (short-term up to 150℃), with excellent low-temperature performance.

Electrical insulation: Excellent electrical insulation performance, suitable for electrical components.

Lightweight: With a density of approximately 1.15-1.16g /cm³, it is lighter than metal and can replace some metal components.

2. Product application fields

Industrial components: gears, bearings, pulleys, guide rails, shaft sleeves, etc.

Mining machinery: Wear-resistant liners, conveyor components.

Textile machinery: High-speed rotating parts (such as shuttles, yarn guides).

Automotive industry: transmission parts, gaskets, sealing rings.

Electronic and electrical: Insulating brackets, cable sheaths.

Food equipment: Conveyor belts and rollers that comply with FDA standards (specific certifications required).

3. Processing technology

Casting molding: Molten caprolactam monomer is injected into the mold, and under the action of a catalyst, it polymerizes and solidifies to produce large or complex-shaped components.

Post-processing: Supports mechanical processing such as turning, drilling and tapping, with high dimensional flexibility.

4. Product advantages

Maintenance-free: Reduce maintenance costs and avoid oil stains.

Noise reduction and shock absorption: The operating noise is lower than that of metal parts.

Fatigue resistance: Resistant to repeated impacts and long service life.

Customization: Performance can be adjusted through additives (such as MoS₂ to enhance wear resistance and carbon fiber to increase strength).

5. Technical Parameters (Typical Values)

Project value

Tensile strength: 70-90 MPa

Bending strength: 100-120 MPa

Impact strength (notch) : 5-10 kJ/m²

Rockwell hardness: R110-R120

Water absorption rate (24 hours) : 0.8%-1.5%

6. Precautions

Environmental adaptability: UV inhibitors should be added for long-term exposure to ultraviolet rays. A humid environment may affect dimensional stability (which can be improved through modification).

Installation requirements: Avoid interference fit and prevent internal stress cracking.

When replacing metals: The structure needs to be redesigned according to the load to compensate for the difference in rigidity.

7. Common specifications

Dimensions: Bars (diameter 10-500mm), plates (thickness 5-200mm), pipes and custom special-shaped parts.

Color: Natural ivory white, customizable black, green, etc.

MC nylon is an economical and efficient engineering plastic solution, especially suitable for complex working conditions that require wear resistance, lightweight or insulation. The specific selection should be based on the assessment of load, temperature and chemical environment.
