PP Processing Parts Customized Special Shaped Parts

PP parts (polypropylene parts) are functional plastic components made from polypropylene (PP) resin through processes such as injection molding, extrusion, thermoforming, and machining. PP resin is a semi-crystalline thermoplastic polymer formed by the polymerization of propylene monomer (C₃H₆). Its molecular chain contains a large number of regularly spaced methyl pendant groups (-CH₃), which impart the material with lightweight, high chemical resistance, excellent flexural fatigue resistance, and good processing fluidity. Its rigidity, toughness, and heat resistance can be further optimized by adjusting the polymerization process (e.g., homopolymer vs. copolymer PP) and adding additives (e.g., impact modifiers, nucleating agents).

PP part has a smooth surface (roughness Ra < 0.4μm), uniform color, and a density of only 0.90-0.91g/cm³ (the lightest of all plastics). Common forms include injection molded parts (such as gears and housings), extruded parts (such as pipes and plates), thermoformed parts (such as containers and pallets), and machined parts (such as precision bushings and connectors). They are widely used in the automotive, home appliance, packaging, medical device, and daily necessities industries.

Product Advantages

Lightweight and Corrosion-Resistant

The ultra-low density (0.90 g/cm³) and excellent chemical resistance of PP parts make them a preferred material for chemical containers, daily necessities, and food packaging. For example:

• Chemical Storage Tanks and Pipe Fittings: Used in storage barrels and valve seals for acid and alkali solutions (such as dilute sulfuric acid and sodium hydroxide solutions). PP parts can withstand immersion in acids/alkalis with concentrations less than 90% for over a year without swelling or deformation (service life >5 years);

• Food-Grade Containers: Plastic lunch boxes, water cups, and food storage containers (transparent or white PP) are heat-resistant (microwaveable up to 120°C for short periods) and non-toxic, meeting food safety standards;

• Household Cleaning Tools: Mop handle connectors and toilet brush handles (copolymer PP for enhanced toughness) are drop-resistant and resistant to cleaning agents.

Flexural Fatigue Resistance

The excellent flexural fatigue resistance of PP parts makes them particularly suitable for structures that require repeated movement (such as hinges and shafts). For example:

• Plastic hinges: The continuous opening and closing parts of plastic bottle caps (such as beverage bottles and cosmetic bottles). PP parts can withstand >100,000 openings and closings.

• Moving parts for home appliances: Washing machine door hinges and vacuum cleaner hose connectors, which withstand long-term use without loosening or deformation.

Easy Processing and Low Cost

The low raw material cost and excellent processing fluidity of PP processing part significantly reduce manufacturing costs. For example:

• Automotive interior parts: Instrument panel frames and door panel trim strips. PP parts cost only 50% of PA6 per unit, and their lightweight design improves fuel economy.

• Mass production of daily necessities: Plastic hangers and storage boxes. Low mold costs and short production cycles make them suitable for small batches and a wide variety of products.
