Plastic hangers raw materials mainly includes Polypropylene (PP), Polystyrene (PS),Polyvinyl chloride (PVC) and so on.
The commonly used raw materials for plastic hangers include polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene copolymer (ABS), polycarbonate (PC), polyvinyl chloride (PVC), ethylene vinyl acetate copolymer (EVA), and silicone. These materials have their own characteristics in terms of physical and chemical properties, and are suitable for different application scenarios.
Each plastic hanger raw materials different character and application are as following:
- Polypropylene (PP)
- Polystyrene (PS)
- Polyvinyl chloride (PVC)
- Acrylonitrile butadiene styrene copolymer (ABS)
- Other plastic materials
Plastic hangers raw materials : Polypropylene (PP)
Polypropylene (PP) has a wide range of applications in the manufacturing of plastic hangers, mainly due to its excellent physical properties and chemical stability. PP material has low density, high strength, and good heat resistance, making it suitable for making general mechanical parts, corrosion-resistant parts, and insulation parts.
Polypropylene (PP) as a hanger material has the following advantages:
Lightweight and High Strength
PP has a density of 0.9-0.91g/cm ³, making it one of the lightest plastics currently available. It also has high strength and hardness, and can withstand repeated folding without deformation
This feature makes PP hangers very practical in both home and commercial environments.
Good heat resistance
PP material has good electrical properties and high-frequency insulation when used at around 100 ℃, suitable for making general mechanical parts, corrosion-resistant parts, and insulation parts
This enables PP hangers to maintain stable performance even in high temperature environments.
Chemical stability
PP has excellent chemical stability and has almost no effect on acids, bases, organic solvents, etc., making it suitable for use in food and medical supplies
This characteristic ensures the durability and safety of the material when making hangers.
Environmental friendliness
PP material is the most friendly to people and the environment, and can be used to make high-temperature resistant baby bottles, water cups, plastic lunch boxes and other daily necessities. PP material is recyclable and only produces trace amounts of ash after incineration, with no harmful volatiles. This makes PP hangers have significant advantages in terms of environmental protection.
Cost effectiveness
PP is the cheapest among the three common hanger materials (PS, ABS, PP), and has relatively less shrinkage during production, making it a cost-effective option. This makes PP hangers more competitive in the market.
Processing performance
PP material has good plasticity and formability, suitable for injection molding, and can produce hangers of various shapes and sizes. In addition, PP material has good fluidity, but the shrinkage range and value are relatively large, so attention should be paid to mold design and cooling control.
Plastic hangers raw materials: Polystyrene (PS)
Polystyrene (PS) has high transparency and good thermoplastic flowability, making it suitable for injection molding material. It performs well in terms of dimensional stability and wear resistance, but is prone to combustion and has poor wear resistance. PS has good heat resistance, but it is very brittle when the temperature is above 0 ℃, so it performs poorly in applications that require impact resistance. PS has low impact strength and is prone to becoming brittle at low temperatures.
The application advantages of PS in the manufacturing of plastic hangers.
Transparency requirements
PS is the only hanger material that can achieve high transparency, suitable for displaying clothing details such as suit racks, underwear racks, etc.
Processing convenience
Good melt flowability, suitable for complex structure injection molding (such as anti slip hooks and hollow designs), with a maximum flow length to thickness ratio of 200:1.
No need for pre drying (water absorption rate<0.05%), shortening the production cycle.
Cost effectiveness
The raw material price is lower than ABS, and the injection molding energy consumption is low (mold temperature<70 ° C), with obvious comprehensive cost advantages
Plastic hangers raw materials: Polyvinyl chloride (PVC)
Polyvinyl chloride is one of common plastic materials with good mechanical properties and chemical resistance.
Polyvinyl chloride (PVC) uses as a raw material for plastic hangers mainly. Because it has good mechanical properties, chemical corrosion resistance, insulation, and processing performance. Stabilizers, plasticizers, fillers and other additives can be added to PVC materials during the manufacturing process to give them different physical and mechanical properties.
The application of PVC in plastic hooks has certain advantages and disadvantages
Advantages:
Lightweight and easy to install
PVC material is lightweight, easy to install, and suitable for manufacturing various hooks.
Waterproof and moisture-proof
PVC has good waterproof and moisture-proof properties, suitable for humid environments.
Chemical corrosion resistance
PVC has good resistance to various chemicals and is suitable for industrial and daily applications.
Low cost
The production cost of PVC is relatively low, making it a popular choice for many applications.
Flame retardancy
PVC has flame retardant properties, which improve the safety of the product.
Disadvantages
Poor high temperature resistance
PVC is prone to deformation in high temperature environments, which limits its application in such environments.
Fast aging speed
PVC materials age quickly, are prone to discoloration, and have a short service life, usually 3-5 years.
Low environmental friendliness
Waste PVC materials are difficult to dispose of and cause pollution to the environment.
Unstable physical properties
Even in the absence of water, PVC materials may deform over time.
Possible release of harmful substances
PVC may contain plasticizers, which can be released at high temperatures and pose a risk to human health.
Acrylonitrile butadiene styrene copolymer (ABS)
Acrylonitrile butadiene styrene copolymer ABS plastic has good comprehensive performance and impact resistance.This is suitable for making high-quality hangers.
The application characteristics of ABS in the manufacturing of plastic hangers are mainly reflected in the following aspects:
High strength and toughness
ABS plastic has excellent impact resistance and toughness, and can withstand large weights and external forces, making it suitable for making hangers that require load-bearing.
Good processing performance
ABS is easy to process and has good dimensional and thermal stability, suitable for injection molding, and can manufacture hangers with complex shapes.
Strong surface treatment ability
ABS surface can be treated with flocking, electroplating, oil spraying, etc., suitable for making high-end appearance hangers, such as antique copper color, wood grain and other effects.
High cost-effectiveness
ABS is a low-cost engineering plastic with good processing performance, suitable for large-scale production.
Chemical resistance and electrical performance
ABS has good resistance to water, inorganic acids, alkalis, etc., and also has good electrical insulation performance.
Easy to color and diverse
ABS can be modulated into various colors, with strong adaptability, suitable for hanger designs of different styles and purposes.
ABS has the advantages of high strength, good processing performance, strong surface treatment ability, and low cost in the manufacturing of plastic hangers, making it an ideal material for producing high-end plastic hangers.
Other plastic materials
Other plastic materials including high-density polyethylene (HDPE), polyethylene terephthalate glycol (PETG), etc. They are also used to make different types of plastic hangers.
Therefore, through above introduction, the selection of these plastic materials depends on the specific use of the hanger, performance requirements and cost considerations.
