Comparison of CNC Machining Materials

CPVC (Chlorinated Polyvinyl Chloride) is a thermoplastic plastic obtained by chlorination modification of polyvinyl chloride (PVC). Such structural changes enable it to far outperform ordinary PVC in terms of heat resistance, mechanical properties, and chemical resistance, making it an ideal material for high-temperature and corrosive environments.

PEI (polyetherimide) is a high-performance thermoplastic engineering plastic that combines excellent heat resistance, mechanical properties, and chemical stability, enabling it to be widely used in high-end industrial fields such as aerospace, electronics and electrical engineering, and medical equipment.

Polyvinyl chloride (PVC) is a widely used thermoplastic polymer material characterized by excellent mechanical properties, outstanding corrosion resistance, and superior electrical insulation performance. By incorporating various additives, it can be tailored to meet customized requirements. Owing to its unique combination of properties, PVC finds extensive applications in fields such as construction, industry, packaging, and healthcare.

Nylon is a versatile and widely used material in CNC machining due to its exceptional properties. Its high tensile strength, low coefficient of friction, and resistance to wear and abrasion make it an excellent choice for applications requiring durability and reliability, such as gears, bushings, and bearings. Additionally, nylon’s low moisture absorption and good dimensional stability ensure consistent performance even in humid or varying temperature conditions.

Its ease of machining, coupled with its chemical resistance, also makes it suitable for applications in the automotive, aerospace, and medical industries. With its remarkable combination of properties, nylon stands out as a versatile and reliable material for a diverse range of CNC machining applications.
