An information resource on the plasticiser butyl benzyl phthalate (BBP)
 BBP - a plasticiser critical for the
efficiency of plastic processing
Butyl Benzyl Phthalate is an unusual plasticiser because of its
chemical asymmetry which results in unique performance properties.
Its production process is also different from other well known
phthalates.
More than 90% of BBP is used for plasticising PVC or other
polymers. Plasticisers are in general high boiling point compounds
that, when incorporated into a polymer, cause a greater flexibility
and workability of the material.
The plasticiser that saves energy and improves life
quality
One of the manufacturing benefits of using BBP is that it allows
PVC transformers to operate with less energy input than with many
similar plasticisers.
The BBP-plasticised polymeric material has consumer and
industrial uses such as flooring, sealants, and coatings.
It is used widely by the flooring industry because it adds
surface properties to flooring materials that minimise maintenance
and give it a prolonged life.
Butyl Benzyl Phthalate is also a critical component in seals for
insulating double glazing, providing personal comfort and
considerable energy savings to homeowners, businesses and public
authorities.
Although BBP constitutes only a small fraction of the total
phthalate plasticisers in everyday use it is nevertheless
among the best documented plasticisers and chemicals. A large body
of scientific evidence accumulated since the early 1960s by
industry and academia has demonstrated that BBP can be safely used
and without harm to human health or the environment.
