Plastic Rubber
Plastic rubber is actually another name for thermoplastic rubber, which combines the processability of plastics with the flexibility and durability of rubbers. It is lightweight, formable and able to withstand repeated use.
Good for Window Clings
Thermoplastic rubber material is good for window clings as it is able to stand up to temperatures approaching 80 degrees Fahrenheit. The sun often heats windows, especially in the summer, to temperatures such as these, so it is a good idea to manufacture a window cling that can stand up to heat to avoid melting of plastic.
Manufacturers
Many manufacturers in Japan and China use plastic rubber in their window clings, as the material is both durable and inexpensive. Shenzhen Kerry Plastic Products in China, for example, offers thermoplastic rubber window clings that are safe and nontoxic.
