Technical Field

[0001] The utility model relates to the technical field of plastic material testing equipment, in particular to a testing equipment used for testing the performance of plastic materials. Background Art

[0002] Plastics are synthetic high-molecular compounds, also known as polymers or macromolecules, and are commonly referred to as plastics or resins. They can freely change shape and form. They are made from monomeric raw materials through synthesis or condensation reactions. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] Plastic is a common item in our daily lives. It's strong and durable, serving as a replacement for wood, steel, and other materials. Plastic's wide application stems from its ability to be modified in composition and form, creating a wide variety of shapes and products, and its relatively low price. Ultimately, plastic is a synthetic chemical, and its chemical name is often used to distinguish different types of plastic.
