Can I apply a Mirror effect on plastic?

Hi There,

My name is Benjamin, and I live in Johannesburg, South Africa.

I'm a 4th year student at Wits University. Over the past few months, I've been working on a project that involves light, more specifically the guidance of a ray of light. For a light source I'm using a 120w light bulb.

I would like to know, would it be possible to apply a high reflective mirror finish on the Inside Diameter of a plastic tube?

If so, what is the process called and where can it be done?

Is the Mirror finish, heat resistant?
Do I have to use a specific type of plastic for this mirror effect?

I have heard of "decorative chrome" what is it and on what material can it be applied onto?

I have thought of lining the inside diameter (tube) with a reflective mirror film or sheet such as Silverlux, Mylar or a Acrylic Mirror Sheet, but theses are hard to find.

Any help form you will be greatly appreciated.

Regards,
