PC+GF
Type: PC+GF
Impact Resistance, Strength, Aging Resistance
PC+GF (polycarbonate + glass fiber reinforced composite material) is a reinforced engineering plastic made by adding glass fiber (abbreviated as GF) to a polycarbonate (PC) matrix. The addition of glass fiber can significantly improve the mechanical properties and stability of pure PC while retaining some of PC’s excellent inherent properties, making it suitable for scenarios with high requirements for strength, rigidity, and dimensional accuracy. It features high strength, high rigidity, and heat resistance, and is ideal for automotive parts, electrical enclosures, and structural components.
TPU
Type: TPU
Impact Resistance, Wear Resistant, Chemical Resistant, Aging Resistance
TPU (Thermoplastic Polyurethane), commonly known as urethane rubber, is a thermoplastic elastomer. It features excellent elasticity, abrasion resistance, and chemical corrosion resistance, and is widely used in applications such as mobile phone cases (soft shells), sports shoe soles, and medical catheters.
PC+ABS
Type: PC+ABS
Impact Resistance, Strength
PC+ABS is a blend-modified material that combines the advantages of both materials. It not only inherits the high impact resistance of PC but also the material strength of ABS, while improving its heat resistance. It is often used in electronic product casings, automotive interiors, consumer products, and more.
CPVC
Type: CPVC
Temperature Resistant, Chemical Resistant, Flame Retardancy
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.

HIPS
Type: HIPS
Impact Resistance, Economical, Electrical Insulation
High Impact Polystyrene (HIPS) is a low-cost and easily processable plastic material. It is often used in the manufacturing of low-strength structural components in scenarios where comprehensive requirements for a material’s impact resistance, processability, and cost are required. Additionally, with its excellent dimensional stability and ease of being painted and bonded, it has become an ideal material for prototyping.
PC
Type: PC
Impact Resistance, Processability
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.
PMMA (Acrylic)
Type: PMMA (Acrylic)
Impact Resistance, High Transparency, Weather Resistance
Acrylic (also known as polymethyl methacrylate, PMMA) boasts not only excellent optical performance but also outstanding UV resistance. With a light transmittance of up to 92%—comparable to glass—it has become a popular material in scenarios ranging from neon signs in shopping malls and display case panels in museums to precision optical lenses and stage light covers.
PEEK
Type: PEEK
Impact Resistance, Chemical Resistant, Food Grade, High Temp, Sterilizable
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.
TPU
Type: TPU
Impact Resistance, Wear Resistance, Chemical Resistant, Aging Resistance
TPU (Thermoplastic Polyurethane), commonly known as urethane rubber, is a thermoplastic elastomer. It features excellent elasticity, abrasion resistance, and chemical corrosion resistance, and is widely used in applications such as mobile phone cases (soft shells), sports shoe soles, and medical catheters.
PA (Nylon)
Type: PA (Nylon)
Wear Resistance, Strength, Chemical Resistant, Self-lubrication
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.
POM (Delrin)
Type: POM (Delrin)
Impact Resistance, Chemical Resistant
Polyoxymethylene (POM) is a premium high-performance engineering plastic. Known for its metal-like mechanical strength, it offers exceptional hardness, rigidity, impact and fatigue resistance, as well as outstanding wear resistance and self-lubrication. POM also provides excellent dimensional stability, strong chemical resistance, and ease of processing. With this unique combination of properties, it has become a preferred material across industries such as machinery, automotive, electronics, and medical devices—making it an ideal replacement for metal in manufacturing high-precision, wear-resistant components.
