PB-1 Properties

Polybutene-1 (PB-1) Properties

In contrast to other competitive thermoplastics used in pressurised piping applications, performance modification of the material via compounding, cross-linking or copolymerisation is not necessary for PB-1 piping systems to fulfil the stringent performance standards applied to their use. Compared to other polyolefins, PB-1 has a higher level of resistance to strain under continually applied stress under heat over long periods of time.

PB-1 material properties

The following table illustrates the physical, mechanical and thermal properties of Polybutene-1. The values shown are typical mid-range figures and should not be considered as a specification - in fact, several different grades of Polybutene-1 are produced with properties tailored to satisfy different applicational requirements.
