It’s all there in glorious colour!
A new brochure from Teknor Apex explains how designers,
processors, and OEMs benefit from this custom compounder’s
diverse thermoplastic technologies and its international supply
capabilities.
The colourful 12-page
publication reports that
Teknor Apex draws on
a database of 40,000
formulations and uses
manufacturing capacity
on three continents to
supply compounds that
already comply with key
international standards.
One special capability
cited is that of providing
identical compounds to
globalised customers with multiple plant locations. Details on
the following broad compounding groups are presented,
including many product ranges in each group and the markets
served:
Vinyl; thermoplastic elastomers (TPEs); engineered
thermoplastics (ETPs); colourants; speciality compounding.

New brochure from Teknor Apex m
LaserXtens – Zwick’s latest strain measurement system –
has successfully been used for applications in temperature
chambers where materials are typically exposed to
temperatures from -70 to +250°C whilst being subjected
to tensile or compressive loads.
Such tests are very important for the automotive industry
where the measurement of both axial and transverse strain
is often required.
laserXtens measures bi-axial strain without any specimen
contact and without the need to attach any marks to the
specimen. Part of the specimen surface is illuminated
using the principle of laser speckle interferometry.
As the specimen is subjected to load, the reflected speckle
pattern is tracked by two digital cameras, and highly
advanced real-time software algorithms convert this data
directly into strain.
The tests carried out in the temperature chamber revealed
that this measurement technology was not adversely
affected by the thin layer of frost which had formed on the
specimen. The speckle pattern was easily detected and
could be tracked during the tests.
Only a window is required in order for laserXtens to ‘see’
the specimen inside the temperature chamber so
laserXtens offers significant benefits in terms of its ease of
use. Meeting class 1 of ISO 9513 (class B2–ASTM E83),
the extensometer remains outside the testing environment
and measures strain up to failure. Zwick believes that this
device will revolutionise the measurement of strain on
specimens under environmental conditions.
