Butyl rubber, known as poly iso butylene is a mixture of 98 percent poly iso butylenes
and 2 percent isoprene and was invented in 1937 by William J Sparks and Robert M
Thomas working for the standard oil company, now Exon Mobil and the first batch was
mixed in a washing machine purchased from Sears Roebuck .
Butyl rubber has now been manufactured in New Zealand for over 35 years
During the 1970s it was clear that the conventional flat roofs of tar and bitchimin
could not cope under New Zealand’s harsh ultra violet climate and major lending institutions
refused to lend to these buildings. It was during this time that butyl membranes
came to the forefront ,establishing itself as the dominant product in the market
It is estimated that THE RUBBER ROOFING CO BUTYL has been used in over 35000 contracts
and is sold throughout new Zealand
It can be found in Japan, Shanghai, South Korea, Los Angeles, Siberia , Pacific Islands
