A
cluster of hi-tech firms could set up to support the work of those moving
into the county. It could also help stem the brain drain of Cornish
youngsters forced to leave the county to find work.
Dr Herbert Fitz the inventor of ETFE report 11/03/01 Thank you for sending this email
Dear Keith,
Congratulation to Your www.site
eden .It might interest You - the ETFE -Fluoropolymer film was invented
and developed 25 years ago by the Hoechst A.G.
/ Germany / Gendorf works ( Bavaria ) - now
( since 1996 DYNEON GmbH = 3 M company / USA ).In the early days the
basic idea was to use the film for solar -collectors , later on as a
long lasting membrane material for roofing systems. Field testing of the
ETFE - film in arizona / USA showed no change in the optical
& mechanical properties after 10 years exposure and we have now over
20 years samples - exposed to weather in
germany - no change at all .
In the fluoropolymer family - ETFE as a film
for roofing systems - shows the most versatile
properties .The coming development is a coated ETFE - filament - fabric
.
Anyhow - I am very pleased what happened in
Your country in the use of the ETFE -
film .
Last but not least - the ETFE - film was
created in my lab - when I was a young
polymerchemist at Hoechst A.G.
Wishing You and Your family the very best -
Yours sincerely
Dr.Herbert Fitz ( retired polymerchemist
Hoechst.A.G )
Dear Keith ,
P.S.
Thanks for your e - mail today .Lets see who
might be interested in the ETFE Film
story .
What I have not mentioned in my story was ,
that the ETFE film compared with
window glass ( green house quality ) shows no change of the the solar -
spectrum ( daylight / sunlight ) . If
You grow tomatos , roses and so on - plants which need the UV
light from the sun - You will find a
remarkable difference in the growing results and the quality
.( taste of the tomatos ) .
regards - the very best : Herbert (
Dr.H.Fitz )
