PP injection molding services
This thermoplastic injection molding material is widely used in the food storage and packaging industry because it doesn’t let chemicals mix with food products. Polypropylene (PP) can be washed in hot water without degrading, and it has high chemical and moisture resistance. PP has incredible impact strength, elasticity, and toughness. Designers should also note that PP is easy to recycle, and because of its flexibility, it can be used to make live hinges that can be bent many times without tearing.
Description
Advantages of PP material
- small relative density, only 0.89-0.91, is one of the lightest varieties of plastics.
- good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding and processing performance.
- with high heat resistance, continuous use temperature up to 110-120 ℃. 4.
- good chemical properties, almost no water absorption, and most chemicals do not react. 5.
- Pure texture, non-toxic. 6.
- good electrical insulation.
- Transparency of polypropylene products is better than that of HDPE products.
Disadvantages of PP material
- The products have poor cold resistance and low impact strength at low temperature.
- The products are susceptible to aging by light, heat and oxygen in use.
- bad colorability.
- easy to burn. 5.
- poor toughness, high static electricity, poor dyeing, printing and adhesion.
Application areas of PP materials
Polypropylene (PP) is one of the top five general-purpose plastics and is used in a wide range of applications in daily life.
As a food-grade plastic, it is widely used in food packaging, such as foam boxes, PP plastic cups and so on.
Polypropylene can be divided into five categories according to its main applications: PP injection molding, PP drawing, PP fiber, PP film, and PP pipe.
- Woven products: PP consumed by woven products is mainly used for packaging of grain, fertilizer and cement, etc.
- Injection molded products:Injection molded products are mainly used in small home appliances, daily necessities, toys, washing machines, automobiles and crates.
- film products: polypropylene film mainly includes BOPP, CPP, general packaging film and microporous film, etc. BOPP has many excellent characteristics such as light weight, high mechanical strength, non-toxic, transparent, moisture-proof, etc. It is widely used in packaging, electrical, electronic and electrical appliances, tape, label film, film, lamination and many other fields, of which the packaging industry uses the largest amount.
- Fiber products: polypropylene fiber is a fiber product made from polypropylene by melt spinning. Because polypropylene fiber has many excellent properties, and therefore in the decoration, industry, clothing in three major areas of increasingly widespread application, has become the second largest variety of synthetic fibers.
