This synthetic leather is durable
and abrasion resistant
A prototype of the newly developed
SilSense material for car seat covers
(photo) was exhibited at the Auto
Expo Components trade show (New
Delhi, India; January 12-15). SilSense
material is a non-animal synthetic
leather that has low volatile organic
compound (VOC) content, because
it is produced through a solvent-free
process that is cleaner than other
products currently used in the market
for vegan synthetic leather. The new
material has a leather-feel soft touch
and comfort, and it can be provided
in different textures and colors. The
greatest benefit is its high durability
and performance, said to be better
than genuine leather and much better
than polyvinylchloride (PVC), the
company says. SilSense also has
a strong resistance to abrasion and
tear, combined with an excellent heat
and ultraviolet (UV) resistance. - Lubrizol

DuPont
A new antioxidant and
ultraviolet stabilizer
This company manufactures a comprehensive
range
makes
it possible to achieve a longer
service lifetime for polyolefins and
engineering plastics exposed to outdoor
weathering. The product was
developed to be suitable for polyolefins
intended for use in contact with
food. - Songwon Industrial Co.,
Ltd., Ulsan, South Korea

This architectural fabric takes
of antioxidants
and UV stabilizers in a full range of
physical product forms. It recently
expanded its portfolio with two new
products: Songnox 9228 antioxidant
and Songsorb 1164 UV absorber,
which are suitable for packaging, agriculture,
building and construction,
as well as home and personal care
applications. Due to its excellent hydrolytic
stability, Songnox 9228 antioxidant
overcomes the challenges
traditional high-performance phosphites/phosphonites
face by allowing
more severe polyolefin processing,
especially at high temperatures. In
addition to this, it also delivers excellent
color protection for Cr-type
high-density polyethylene (HDPE),
polypropylene
(PP)
and
engineering
resins. The latest addition to the
company's range of UV absorbers is
a triazine, Songsorb 1164 protects
plastics against UV light degradation.
Compared to conventional benzotriazole
UV absorbers, Songsorb 1164

advantage of natural lighting
Last October, this company and Seaman
Corp. (www.seamancorp.com)
launched a new Shelter-Rite High
Light Transmission architectural fabric
(photo) using transparent Tedlar
PVF film. This new architectural fabric
is suitable for structures that require
natural light, such as sports arenas,
event venues and greenhouses.
Transparent UV-blocking Tedlar film is
a high-performance material that provides
decades of durable protection.
With excellent weatherability and dirtshedding
properties, Tedlar preserves
the life and aesthetics of architectural
fabric structures even in extremely
harsh environments. It provides a
high level of protection against UV
light, moisture, rain and pollution. -

New coatings for
HVAC applications
Polydure coatings contain a proprietary
resin technology specifically
tailored to the needs of the heating,
ventilation and air-conditioning
(HVAC) segment, including commercial,
industrial and residential applications.
The proven coating system
provides a trouble-free application
combined with a consistent, smooth
film. It contains excellent forming
properties and provides batch consistency,
along with a broad range of
color, gloss and texture options. The
Polydure portfolio
includes focusformulated
primers as part of the
coating system, allowing the topcoat
to perform at an optimal level. The
primers utilize formulation models for
best-in-class performance, including
UV stability, corrosion resistance,
delamination and intercoat adhesion.
In addition, they contain Dual Action
