DSM Engineering Plastic Products Inc. announced
that its KetronTM polyarylether-ketone (PEEK)
high-performance stock shapes are now available in rod
diameters up to 200 mm, tubular bar up to 140 mm OD,
and plate in widths up to 615 mm. Larger sizes allow
multiple parts to be machined with less waste.
Ciba Specialty Chemicals, Performance Polymers
has introduced the ResinfusionTM 8603 two-component
epoxy for infusing composite parts for aerospace, transportation,
and marine applications. The infusion is done via processes
including vacuum-assisted resin transfer molding (VARTM),
the Seemann Composite Resin Infusion Molding Process
(SCRIMPTM), and resin transfer molding (RTM).
Resinfusion 8603 has a 78-minute gel time for easy handling,
and low viscosity of 260 cP for good wet-out of fabrics
used in infusion processes, the company says.
CYRO Industries announced a new generation of
ACRYLITEr AR abrasion-resistant acrylic sheet that maintains
optical clarity, the company says. The sheet is available
with the coating on one or both sides. Applications
include those subjected to heavy public contact and
cleaning, such as public transportation glazing.
THERMOUNTr RTTM laminate and prepeg employs
DuPont's Type N710 reinforcement, for use in
printed wiring board and chip carrier manufacturing.
The company says it developed the reinforcement for
high-volume, commercial electronic applications that
use high-density interconnect technologies.
