Transparent resin plates: how to choose the correct one

Transparent resins are indeed among the most used and versatile materials used in many industries. As we have seen in our previous blog post, there are different types of transparent resins available in meviy for both sheet metals and machined plates.  Each type has particular characteristics that will make your specific part fit your required needs. In this article we’ll be seeing the difference among the four main transparent resins and how they can be applied in transparent resins plates. 

Transparent resin plates: materials comparison

Among the materials often used as transparent resin plates, this article introduces the characteristics and usage scenarios of the four most popular types: PET, acrylic, polycarbonate and PVC. The characteristics of the 4 materials are summarized in the comparison table below.
