Injection Molding Materials

Apply your deep knowledge in the application of molding materials offered by FirstMold, to produce the products that you see in your mind.

How Many Types?

Injection Molding Materials Classification

We classify plastics into different classifications to ease the material selection for you. We cover all the way from standard thermoplastics, which are a great fit for many applications, to custom-engineered thermoplastics and high-performance polymers, each with properties tailored for various conditions.

Future innovations include modified plastics more customized for diverse performance requirements. Developed to make it easy for you to always find the most appropriate choice for your project, the categories cover durability, heat resistance, flexibility and eco-friendly options among other features.

Injection Molding Materials Comparison Chart

We sincerely hope that you can have a deeper understanding of injection molding materials, as this will be greatly beneficial for your product design. In fact, many of our clients have varying degrees of understanding of plastic materials, and a small portion of them even specify particular material suppliers for us to purchase from. We highly encourage you to do this; at the same time, we can also provide various purchase verifications and material testing certifications.
