Plastic Material Overview

Plastic material is a material composed of synthetic polymers and is widely used in various industries. Depending on the chemical composition and production process, plastics can be divided into many types, such as:

  • Thermoplastics: This type of plastic becomes soft when heated, solidifies when cooled, and can be heated and molded multiple times. For example: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and so on.
  • Thermosetting plastics:This type of plastic will undergo a chemical reaction during heating and cannot be softened again after curing. For example: epoxy resin, phenolic resin, polyurethane (PU) and so on.

Plastic materials are widely used in packaging, electronics, electrical appliances, automobiles, construction, and other fields because of their portability, corrosion resistance, easy processing and low cost.

Navigating through numerous plastic resins can be overwhelming. Each resin possesses distinct properties and processing needs. Additionally, various grades exist, incorporating fillers like glass or carbon fibers, along with specific brand variations. This extensive array of options makes plastic molding material selection a challenging task for any project.

Whether you’re delving into medical plastic injection molding, creating molded components for the automotive, or tackling another venture, Jiangzhi experts stand prepared to guide you swiftly from mold design to production.

Notes:

  1. Max Service Temperature is approximate and depends on specific grades and formulations.
  2. Actual performance can vary with factors like load, time, and exposure conditions (e.g., continuous vs. intermittent heat).
  3. Additives can enhance heat resistance for specific applications.

Plastic Parts in Different Industries

Use low-shrinkage, good-flow materials and keep wall thickness uniform. High-shrinkage plastics (like PP, PA) need thinner walls, while high-filled PC may require thicker walls.
PC, PC/ABS, and POM offer high strength and toughness, ideal for load-bearing or impact-prone components. Glass-fiber reinforced grades can further enhance performance.
Yes, PMMA and PC are commonly used for transparent parts. Use optical-grade materials and control processing conditions to avoid bubbles or haziness.
Use engineering plastics like PA, PC, or POM, which maintain strength and shape at elevated temperatures without deforming or losing performance.
POM, PTFE, HDPE, and PP have low water absorption and maintain dimensional stability. Avoid high-absorption plastics (like standard PA) to prevent swelling or deformation.
