Plastic Injection Molding Materials

At Stack Plastics, we work with a wide range of thermoplastic materials in our injection molding processes. We have extensive experience working with everything from “standard” thermoplastic resins to exotic and engineered polymers like Delrin plastic. With our materials expertise, we can provide the option that provides the right physical characteristics for your unique application.

What is A Thermoplastic?

A thermoplastic, or thermoplastic resin, is a type of polymer material that becomes pliable and moldable when heated above a specific temperature and that hardens into a solid when cooled. Most varieties of thermoplastic resin are recyclable, and can be reheated, reshaped, and reused repeatedly.

There are literally hundreds of different types of thermoplastics, each with varying crystalline structures, density, and physical/mechanical characteristics. Each thermoplastic resin offers its own advantages and disadvantages, making it very important to choose the material that is best suited for the environmental and performance requirements of a given application.

Common Thermoplastic Materials

Specialized Thermoplastic Resin Materials

Most of the above thermoplastic resin materials can be blended with carbon fiber additives for increased strength and durability.

Exotic Thermoplastic Resin Materials

Most of the above exotic resins can be blended with carbon fiber additives for increased strength and durability.

Delrin® Plastic

A homopolymer variation of polyoxymethylene (POM), Delrin® plastic is the thermoplastic resin of choice for injection molded parts and products that require high stiffness, low friction, and superior dimensional stability.
