Extrusion 4-2017

Clariant, a world leader in specialty

chemicals, introduced its new heat and

light shield to address strengthening

OEMs’ requirements in automotive

interiors. AddWorks ATR 146 is now

setting a new benchmark, aiming to create

longer-lasting aesthetics and a healthier

environment inside future vehicles due to

reduced Volatile Organic Compounds

(VOC).

requirements for heat stability, light stability and VOC emis-

sions with a low dosage solution.

“Such advanced performance responds precisely to the

emerging trend in the segment for durability and lower VOC

environments, setting the new benchmark for the next gene-

ration of automotive interiors.”

Door to Next-Generation Durable,

Low Emission Automotive

Interiors opened

oon commercially available, AddWorks ATR 146 is a new

low dosage, sulfur-free stabilizer for filled Polypropylene

(TPO) compounds used in interior applications. It offers the

automotive industry unmatched high performance and

reduced VOC emissions in a single solution that goes even

beyond current OEMs’ standard requirements in heat stability.

AddWorks ATR 146 is proven to deliver exceptional heat sta-

bility to TPO compounds, with no surface cracking reported

after 700 hours and beyond @ 150°C when dosed as low as

0.3 percent. This performance level largely exceeds the stan-

dard requirements in the industry for such applications and

outperforms the heat stability of currently available alterna-

tives. Moreover, it displays excellent light stability performance

that protects long term against discoloration.

The outstanding UV and heat protection, plus high resistance

to extraction media like water or detergents, enable typical

TPO-based parts such as dashboards, instrument panels, door

panels, and pillars to maintain their aesthetics for longer than

with traditional stabilizers.

In addition, AddWorks ATR 146 has high compatibility with

the PP polymer and high intrinsic stability that contribute to

reduce blooming and VOC emissions from an injected part. As

a result, AddWorks ATR 146 strongly supports the industry ef-

fort to make the new generation of automotive interiors

healthier and odorless due to reduced VOC emissions.

Emilie Meddah, Global Segment Leader for Automotive Appli-

cations at Clariant, comments: “Today, over 50 percent of

plastics in vehicle interiors are made of polypropylene. With

AddWorks ATR 146, we are excited to offer Tier Ones and

OEMs the opportunity to go beyond the most stringent
