I am creating a tv remote and for that, I am looking for material just like MI tv remote.
It looks like basically, for plastic, you need to mix a Diffuse with a Glossy.
To make it more realistic, use a Fresnel in the Factor of your Mix Shader so that the light will enlight the contour of your object a bit. You can also add a second mix to add a Translucent shader so that the light plays a bit more naturally with the object thickness.
Your object also have a grainy surface, so you need to add some noise: Use a Noise Texture that you plug into a Bump node that you plug into your shaders Normal sockets. As the details are very small, choose a high Scale in the Noise Texture.
