The tensile and
permanent set properties of P-E polymers exhibit remarkable mechanical annealing characteristics.

The company's formulation is said to provide elasticity and strength, puncture resistance, low
permanent set to prevent finger marks and indentation due to handling, high oxygen permeability, moisture barrier properties and cling.
Davison's steel scaffolding
permanent set used throughout along with Peter Mumford's splendid lighting, a production facet upon which so much depends.
Digital cameras give 35mm quality without expensive lighting setups, multicamera shoots cut the time required to complete each scene and a
permanent set - including an entire shopping mall interior - eliminates location moves.
Instead of a
permanent set of company members, Brightling Sea represents an ongoing creative space for collaborative exchange, exploration and artistic cross-fertilisation, manifesting in the form of anything from site specific pieces, to solo work, to inter-disciplinary performance projects.
The involvement throughout from community actors and professionals directed fluently by Jenny Stephens and Kim Greengrass is seamless with touching well shaped performances evoked beneath the
permanent set.
Testing instruments and systems include standard and custom abrasion testers, block ovens, bond testers, brittlepoint testers, durometers, fatigue-to-failure testers, clicker presses, flex testers, molds and dies, impact testers, melt flow indexes,
permanent set testers, plastometers, grips and fixtures, falling weight impact testers, rebound testers, resiliometers, rheometers, specific gravity testers, viscometers and tensile testers for such markets as rubber and plastics, composites, textiles and more.
At the Capulets' rave-up (in a
permanent set which reminded me of a urinaum-Tu rkish bath) the Nurse belts out a neat boogie number into the hand mike.
