In the plastic raw materials market, correct material classification not only concerns performance indicators but also affects supply costs and the success or failure of projects.

From general-purpose polyolefins to special engineering plastics, the compatibility of different polymerization structures, modification systems and processes determines the performance and stability of the products in terminal applications.

As a company with 24 years of experience in international trade, Juyuan offers our clients not only raw materials but also selection ideas based on a classification system and practical procurement plans.

The following content will systematically sort out the professional classification logic of plastic raw materials, helping enterprises optimize their supply structure, control risks and enhance their competitiveness.

I. Classification by performance and application: From general-purpose to high-performance, covering all fields

1. General Purpose Plastics

Representative Materials and Applications:

  ・PE (Polyethylene) : Packaging film, pipes, containers

  ・PP (polypropylene) : Home appliance shells, automotive interiors, medical supplies

  ・PS (Polystyrene) : Stationery, tableware, transparent boxes

  ・PVC (Polyvinyl chloride) : pipes, cables, flooring, door and window profiles

  ・buikspieren: Home appliances, toys, automotive interior parts (with excellent electroplating performance)

💡 Market Characteristics:

General-purpose plastics have stable costs and abundant supplies, making them core materials in the packaging, daily chemical, and construction industries.

2. Engineering Plastics

It features higher mechanical strength, heat resistance and dimensional stability, and is widely used in structural and functional components.

Representative Materials and Applications:

  ・PC (Polycarbonate) : Optical components, safety helmets

  ・PA (Nylon) : Gears, bearings, automotive parts

  ・POM (polyoxymethylene) : Sliding parts, precision structural components

  ・PBT/HUISDIER (polyester type) : Electronic connectors, automotive lighting parts

  ・PMMA (Acrylic) : Lampshades, transparent covers

💡 Market Trends:

The lightweighting of automobiles, the upgrading of home appliances and the precision of electronics have continuously driven the growth in demand for engineering plastics.

3. High-Performance Engineering Plastics

Serving the fields of aerospace, energy, medical care and high-precision equipment.

Representative Materials and Applications:

  ・PEEK: Engine components, aviation structural parts, medical implants

  ・PPS: Pump casing, electrical components, automotive engine system

  ・LCP: High-frequency Microelectronic connector

  ・PI: Flexible circuit boards, heat-resistant films

  ・PES/PSU: Medical housing, filter element assembly

💡 Industry Characteristics:

With high temperature resistance, high strength and high reliability as its core features, it has a high market concentration and its added value far exceeds that of ordinary plastics.

Ii. Classification by the chemical structure of polymers

Iii. Classification by source

  ・Petroleum-based plastics (Petrochemical) : mainstream materials such as PE, PP, PS, PVC, PC, etc.

  ・Bio-based plastics: PLA, PBS, PHA, Bio-PET, Bio-PE; Emphasize environmental protection and sustainable supply chains.

🌿 Trend interpretation:

The annual growth rate of global bio-based plastics is approximately 15%, and R-PET and Bio-PE are becoming the new green favorites of brand enterprises.

Iv. Classification by thermal characteristics

V. Classification by modification system and Functionality
