Virgin Plastic Pellets: Features and Applications
Virgin plastic pellets are an essential component in the plastics industry and are widely used in daily life. In this article, Kanetora will explore the most common types of virgin plastic pellets, such as PE, PP, PVC, along with their features and applications.
1. What are Virgin Plastic Pellets?
Virgin plastic pellets are plastic granules that have not undergone recycling, contain no impurities, and have no additives. They are produced through the fractional distillation of petroleum. The production process of virgin plastic pellets includes the polymerization of basic plastic compounds, which are then processed into plastic pellets for various applications.
The common characteristics of virgin plastic pellets include flexibility, good elasticity, and resistance to warping and pressure. If you are looking for quality and reliability, consider using virgin plastic pellets for your project.
2. Virgin PE (Polyethylene) Pellets
PE plastic, fully known as Polyethylene, is a simple and widely used polymer. PE plastic has a simple molecular structure consisting of long chains of ethylene units bonded together, creating a flexible, elastic plastic with good electrical insulation properties.
Applications:
Virgin PE pellets are widely used in manufacturing. Among virgin plastic pellets, PE is considered one of the safest materials and is commonly used. Statistics show that over 60 million tons of PE plastic are consumed annually, mainly for plastic packaging production.
PE plastic is commonly used to manufacture plastic packaging such as wire insulation, product wrapping films, food wrapping films, plastic bottles, and construction materials.
Virgin PE pellets are categorized into eight types:
-
VLDPE (Very Low-Density Polyethylene)
-
LDPE (Low-Density Polyethylene)
-
LLDPE (Linear Low-Density Polyethylene)
-
MDPE (Medium-Density Polyethylene)
-
HDPE (High-Density Polyethylene)
-
HDXLPE (High-Density Cross-Linked Polyethylene)
-
XLPE (Cross-Linked Polyethylene)
3. Virgin PP (Polypropylene) Pellets
PP plastic, or Polypropylene, has a crystalline structure and is whiter and more transparent than PE plastic. Depending on different crystallization levels, products made from PP can range from transparent to semi-transparent. The most notable feature of PP plastic is its high bending ability, allowing the material to be folded multiple times without breaking—a key advantage over other plastics.
The surface of PP plastic pellets is harder than PE plastic, although not as hard as PS or ABS plastic. This balance of rigidity and flexibility makes PP ideal for household product manufacturing.
Applications:
Thanks to its outstanding properties, PP plastic has diverse applications in daily life and industrial sectors. Its high toughness and durability make it an essential material in various industries. PP also offers good electrical and thermal insulation, expanding its use across many fields.
Due to its high purity, PP plastic is widely used in:
-
Medical equipment
-
Surgical instruments
-
Electrical devices
-
Household appliances
Types of Virgin PP Plastic:
-
Coated PP
-
PP Yarn
-
Injection-molded PP
-
PP Film
-
Block PP
-
Non-woven PP fabric
4. Virgin PVC (Polyvinyl Chloride) Pellets
Virgin PVC plastic (Polyvinyl Chloride) is a flexible plastic formed from the polymerization of vinyl chloride (CH₂=CHCl), abbreviated as VCM.
PVC plastic is one of the earliest and most widely used synthetic materials in industrial production.
Characteristics of PVC Plastic:
-
Non-toxic, odorless, and solid in form
-
High impact and load resistance
-
Weather-resistant, corrosion-resistant, shockproof, and abrasion-resistant
-
High chemical stability and flexibility
-
UV-resistant, preventing aging in outdoor conditions
-
Flame-retardant and electrically insulating
Applications of PVC Plastic:
-
Construction Materials: Drainage pipes, nuts, roofing sheets, valves, ceiling panels, adhesive tape rolls.
-
Industrial Manufacturing: Automotive parts, insulation materials, artificial carpets.
-
Medical & Daily Life: IV tubes, syringes, respiratory tubes, catheters.
-
Food Packaging: Disposable food containers and packaging films.
5. Virgin ABS (Acrylonitrile Butadiene Styrene) Pellets
Virgin ABS plastic (Acrylonitrile Butadiene Styrene) is a polymer commonly used as a rubber substitute in various industries. It was commercially introduced in the 1950s.
Key Features of ABS Plastic:
-
A thermoplastic material that withstands temperatures from -25°C to 60°C, with a melting point of around 105°C.
-
Easy to process and electroplate
-
Cost-effective and available in various forms
-
Long lifespan and good environmental resistance
-

-
Refrigeration Engineering: Casing for refrigeration equipment.
-
Automotive & Motorcycles: Key material for manufacturing vehicle components.
-
Packaging Industry: Storage boxes, specialty packaging, helmets.
-
Injection-molded products: Keyboard keys, phone casings.
6. Virgin PS (Polystyrene) Pellets
Virgin PS plastic (Polystyrene) is a thermoplastic created through the polymerization of styrene and is recyclable. It was first discovered in 1845 and became commercially available in 1937.
Characteristics of PS Plastic:
-
Hard, odorless, tasteless, and transparent like glass
-
Easily colored and processed via injection molding
-
Lightweight and impact-resistant
-
Can be transformed into EPS (Expanded Polystyrene), commonly known as Styrofoam
Applications of PS Plastic:
-
Food Containers: Disposable food boxes, plastic cups.
-
Household Items: CD/DVD cases, children's toys, kitchenware.
-
Electronics: Computer casings.
⚠️ Caution: PS plastic should not be used for hot food storage (above 70°C) as it may release harmful chemicals.
7. Virgin EVA (Ethylene Vinyl Acetate) Pellets
Virgin EVA plastic (Ethylene Vinyl Acetate Copolymer) is formed by polymerizing ethylene and vinyl acetate.
Key Features of EVA Plastic:
-
Highly flexible and elastic, even at low temperatures
-
Durable in various environmental conditions
-
Water-resistant, ozone-resistant, and UV-resistant
Applications of EVA Plastic:
-
Footwear & Bags: EVA is widely used in shoes, backpacks, and sports equipment due to its shock absorption properties.
