In-mould decoration (IMD) is a manufacturing process used primarily in the production of plastic parts, where decorative patterns, images, or textures are integrated directly into the surface of the plastic during the moulding process. This technique combines the injection moulding of plastic with the application of graphics or decorative films. Here’s how the process generally works: 1. **Preparation of Materials**: A decorative film or graphic is selected and positioned in the mould.

Low-density polyethylene (LDPE) is a type of thermoplastic made from the polymerization of ethylene monomers. It is characterized by its low-density molecular structure, which results in a material that is flexible, resilient, and lightweight. LDPE has a branching structure, which contributes to its low density and affects its physical properties. ### Key Features: 1. **Flexibility**: LDPE is known for its excellent flexibility, making it suitable for applications that require bending or stretching.

Metallised film is a type of flexible packaging film that has a thin layer of metal, usually aluminum, applied to its surface. This layer is typically achieved through a process called vacuum metallization, where metal is vaporized in a vacuum chamber and then deposited onto the film substrate.

An electric road, often referred to in the context of electric vehicle (EV) infrastructure, is a road or roadway system designed to support the charging of electric vehicles while they are in motion. Electric roads can use various technologies to achieve this, including: 1. **Inductive Charging**: This method uses electromagnetic fields to transfer energy between coils embedded in the road and those in the vehicle. As the vehicle drives over these charging sections, it receives power wirelessly.

Poly(ethyl methacrylate) (PEMA) is a synthetic polymer made from the polymerization of ethyl methacrylate monomers. It is a member of the methacrylate family, which includes various acrylic polymers, and is known for its versatility and utility in a variety of applications. ### Properties of Poly(ethyl methacrylate): 1. **Transparency**: PEMA is typically clear and can be made to have various levels of transparency and color.

Polybutylene (PB) is a type of thermoplastic polymer that is produced from the polymerization of butylene monomers. It is known for its flexibility, resistance to low temperatures, and ability to be easily formed into various shapes. PB has been used in a range of applications, including plumbing pipes, fixtures, and fittings, as well as in electrical insulation and various consumer products.

Polypropylene carbonate (PPC) is a type of biopolymer that belongs to the family of polycarbonates. It is synthesized through the polymerization of propylene oxide and carbon dioxide. PPC is notable for its biodegradability, which makes it an attractive alternative to traditional petroleum-based plastics. Key characteristics of polypropylene carbonate include: 1. **Biodegradability**: PPC can decompose under certain environmental conditions, making it more environmentally friendly compared to conventional plastics.

Polytrimethylene terephthalate (PTT) is a type of thermoplastic polymer that is part of the polyester family. It is synthesized from terephthalic acid and 1,3-propanediol. PTT has gained interest for several reasons, including its physical properties, environmental benefits, and potential applications.

Splay, in the context of plastics, refers to a defect that can occur during the injection molding process. It manifests as a flow pattern or streak in the finished molded part, often caused by the flow of the molten plastic during processing. Splay can result in an unsightly appearance and may impact the mechanical properties of the final product.
