Specialised Materials

 

 

 

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!!

Diaphragm Coating Material?
Hand Soap, Graphite, Anti-static Spray and even Wall Paper Paste. None of these were used by Quad. Quad used a soluble nylon called CALATON ® made by I.C.I. (U.K.). It is no longer commercially available. You can still use DIY nylon coatings though.

The common substances mentioned can be bought just about anywhere.
Specialised permanent anti-statics can be bought from computer consumable suppliers.
A soluble nylon ELVAMIDE®; is available from Du Pont and Area 51. DIY soluble nylon is possible, depending on your access to certain chemicals.

The original Quad coating - CALATON CB - is available here - Area 51.
