About Polypropylene Machining
Polypropylene (PP) is a semi-crystalline thermoplastic and bisphenol A (BPA)-free, lightweight plastic that is white and odorless. It comes in two different forms: homopolymer and copolymer. Homopolymer polypropylene is the most commonly used grade, while copolymer polypropylene contains varying proportions of ethylene. Because polypropylene is prone to sticking and melting, its processing can be more difficult than other common plastics. Polypropylene’s excellent chemical resistance and fatigue strength make it particularly suitable for flexible parts and parts exposed to corrosive environments. It also possesses excellent physical properties, such as high strength at low temperatures, good chemical resistance, and the ability to withstand temperatures up to 200°C (392°F). Polypropylene is widely used in the automotive, construction, and medical fields. Its main advantages are its lightweight and high-temperature resistance, making it ideal for applications requiring high durability. These excellent properties have made polypropylene increasingly popular.
Basic Properties of Polypropylene
Polypropylene (homogeneous and copolymer) is a lightweight thermoplastic known for its chemical resistance and flexibility. Its tensile strength is 30-50 MPa, and its elongation at break is 200%-600%. However, due to its relatively low rigidity and low melting point (160-170°C), it is prone to warping and deformation during processing. Therefore, careful selection of tools and control of cutting speed are necessary to achieve optimal processing results.
- Suitable for components exposed to corrosive environments.
- Reduces the overall weight of components.
- Provides durability and abrasion resistance.
- Suitable for flexible components and long-lasting performance.
- Inexpensive, making it suitable for mass production.
- Precision machining is possible with appropriate techniques.

FAQ
Natural polypropylene has limited UV resistance and may degrade with prolonged exposure to sunlight. For outdoor applications, we recommend using black polypropylene with added UV stabilizers or applying a protective coating to extend its lifespan.
Absolutely. With careful design, milling polypropylene can produce thin-walled sections or movable hinges. We will assist you in reviewing and optimizing your documentation.
Due to the difficulty in bonding PP, mechanical fastening or ultrasonic welding is recommended. We offer basic assembly support.
PP offers better chemical resistance and higher temperature resistance (90°C vs 80°C), while HDPE exhibits superior impact resistance at low temperatures. PP is harder and stronger, making it ideal for structural applications and chemical storage tanks.
Yes, polypropylene is an affordable medical-grade plastic. It is widely used in steam sterilization of medical devices, and its increasing popularity in the medical field is attributed to its highly efficient sterilization performance and transparency. Polypropylene's ability to withstand high temperatures, cleaning agents, and disinfectants, coupled with its affordability, ensures its continued use in the healthcare sector for many years.
Yes, polypropylene (PP), while lightweight, is very strong, capable of withstanding considerable loads and exhibiting good fatigue strength. Furthermore, its good resistance to a variety of solvents and chemicals makes it ideal for manufacturing laboratory equipment and versatile containers for various applications.
Polypropylene (PP) can withstand temperatures up to 100°C (212°F) and is resistant to acids, alkalis, and solvents. In extreme environments, the addition of additives (such as glass fiber) can enhance its thermal stability.
Annealing is not mandatory, but it is recommended for high-precision parts to eliminate internal stresses. Surface treatments (such as polishing) can improve the appearance of consumer-facing parts.
Polypropylene has a high ignition point and is considered relatively difficult to ignite. It has good flame retardancy and self-extinguishes when the ignition source is removed. However, it is not completely fire-resistant, so caution is still needed near open flames.
CNC machining is ideal for prototyping, small to medium batch production, and parts with very complex internal structures. PP injection molding, on the other hand, is the most cost-effective solution for mass production of the same parts.
