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.

PET (polyethylene terephthalate) is a common thermoplastic polyester with excellent mechanical properties and strong chemical resistance. It also offers glass-like transparency and luster, with a high light transmittance of about 88–92%, and is widely used in beverage bottles, food packaging, and engineering plastics.

PC (polycarbonate, commonly known as bulletproof glue) is inherently pale yellow or colorless and transparent, featuring hardness, toughness and luster. It boasts prominent advantages: with a light transmittance of 90%, it not only has good mechanical strength but also excellent impact resistance, along with outstanding heat resistance and weatherability.

PEEK (Polyetheretherketone) is a top-performing thermoplastic engineering plastic, featuring excellent high-temperature resistance, robust mechanical properties, versatile corrosion resistance, top-tier biocompatibility, exceptional dimensional stability, and outstanding electrical insulation and radiation resistance. It is widely used in high-end fields such as aerospace, high-end medical care, and electronic semiconductors.

ABS (Acrylonitrile-Butadiene-Styrene Copolymer) is a well-balanced engineering plastic with good mechanical properties, excellent impact resistance, and easy processability. These characteristics have led to its widespread application in fields such as consumer electronics, household appliances, automotive industry, and daily necessities.
