Injection moulding is a typical method of thermoplastic production. While there are several common plastics that can be used for injection moulding, material selection is tricky. Thermoplastic is a term used to describe a substance that is usually made of plastic polymers. This means that it can be remelted, reshaped, and refrozen after it has melted.
There are a variety of plastic injection moulding materials to be used, all serving different purposes.

POLYMETHYL METHACRYLATE (ACRYLIC)
The scientific name for the polymer known as acrylic, acrylic glass, and plexiglass is poly (methyl methacrylate). It is transparent, fragile, and light when unaltered. It transmits light and can be transformed into a variety of shapes, textures, and colour casts. PMMA is excellent for use outside. It won’t corrode and is resistant to weather, UV rays, and the majority of other environmental factors. PMMA is one of the safer plastics because it is BPA-free and recyclable. PMMA is significantly more sustainable as a result. Find out more…
