A Guide to Selecting the Right Stock Shape Plastics for Industrial Manufacturing

In the realm of industrial manufacturing, the selection of the right stock shape of plastics can be the determining factor between success and failure. The material choice affects the final product's functionality and durability and the manufacturing process's efficiency. This blog post provides a comprehensive guide to help you navigate this critical decision.

Throughout this article, we'll explore different types of stock shape plastics, delve into the specific factors that should influence your choice, and illustrate with real-life examples how the right selection can lead to outstanding results. We'll also offer best practices and additional considerations for this process.

Exploring the Different Types of Stock Shape Plastics Available

Stock shape plastics come in various types, each with unique properties and applications. Some common types include polyethylene, polypropylene, PVC, and many more.

Polyethylene, available in variants like high-density polyethylene (HDPE) and ultra-high molecular weight polyethylene (UHMWPE), is renowned for its high impact strength and low coefficient of friction. It finds use in applications like wear strips, gears, and conveyor parts.

Polypropylene, on the other hand, offers excellent chemical resistance, low moisture absorption, and good electrical insulation properties. It is commonly used in packaging, automotive, and electrical applications.

PVC, or polyvinyl chloride, offers excellent flame and weather resistance, making it suitable for outdoor applications, electrical cable insulation, and construction.

Each of these plastics brings unique characteristics to the table, and understanding these properties is key to selecting the right material for your application.

Factors to Consider When Choosing Stock Shape Plastics

Selecting the suitable stock shape plastic is a multidimensional decision that should take into account several factors:

A. Application requirements and performance specifications

  1. Mechanical properties like strength, stiffness, and impact resistance dictate the durability and functionality of the final product. For instance, Ensinger's TECAFORM AH SD, a POM-C material, is known for its high strength and stiffness, making it suitable for gears, bearings, and other high-load parts.
  2. Thermal properties such as temperature resistance and heat transfer are crucial in environments with high or fluctuating temperatures. For instance, Ensinger's TECATRON PPS, due to its excellent thermal stability, is used in demanding applications like automotive and aerospace.
  3. Chemical resistance is vital when the material is exposed to specific substances. Ensinger's TECAFLON PVDF, a fluoropolymer, offers outstanding chemical and UV resistance, making it ideal for applications in chemical processing industries.
  4. Electrical properties such as conductivity and insulation are key considerations for electronic components. TECAPEEK, for example, is a high-performance plastic from Ensinger with excellent dielectric properties.
  5. Environmental considerations like UV resistance and moisture resistance help determine the material's longevity in specific environmental conditions.

B. Manufacturing processes and compatibility

  1. Machinability pertains to the ease of cutting, drilling, and shaping the material. For instance, Ensinger's TECANAT is known for its excellent machinability, making it a popular choice for precision parts.
