Roofing
asphalts
FRIPP
has begun to develop premium quality roofing asphalt and
waterproof materials since the end of 1980s. The catalytic
oxidation process developed by FRIPP can extend the
elasticity range of asphalt and greatly improve the
performances of asphalt under high/low temperatures. This
technology has been applied in Fushun Asphalt Felt Factory
with the products meeting ASTM D312 and ASTM D449.
On
the basis of the development of roofing asphalt, FRIPP
carried out studies on medium and top grades of waterproof
materials.
Through
improving the special process and enhancing good mixture
of polymer and asphalt, the medium grade waterproof
product has heat resistance over 90≧
and flexibility lower than -2≧,
free from the problem of ＾heat flowing and cold
cracking￣ which is common among ordinary roofing
asphalts; the top grade waterproof product has its
elasticity range greatly broadened with its heat
resistance over 90≧ and
flexibility lower than -25≧.
Both products meet the UNE104-281 of Spain.
