Material Name |
Purpose |

Mylar®, Melinex®, Clysar®, Hostaphan®. All of these are proprietary names for P.E.T. - Polyethylene Pterypthalate film. Mylar® is considered the best material, as it will hold any given tension, short of breaking, for many years. The replacement film available on this site is just as good - Area 51 - we have had it made to specification for this speaker. |
12 mm Mylar® is used frequently to make treble and bass diaphragms. The original Quad used 6 micron tensilised Mylar® in the treble panel. Although PETP films are available down to 0.9mm in thickness, it is in debate that most would hold the necessary tensions for long, although 6 mm Hostaphan® has shown some promise recently in trials. Tensilised films are still available, though you generally find you have to buy a minimum lot of 8 tonnes of the stuff!!
