Customer’s Expectations for Interior
Surfaces & Materials are Very High
To meet customer‘s expectations the following parameters for materials
need to be fulfilled:
Design (color, structure of surface, „leather like“ appearance)
Haptic, „Touch“ (soft, hard, sticky, smooth)
Durability (is it sensitive to damage by UV light or heat ?)
Odor free (new car smell vs. new car malodor)
No fogging („smeary window“)
All properties are effected by antiscratch additives
The quality impression of the interior determines the quality
impression of the total car!

Door Panels are a Typical Application
for Antiscratch Additives
Antiscratch properties are needed
because
Car customers & designers like grained
surfaces (“leather style”)
These surfaces are very sensitive to
scratch, e.g. damages of door panels
Industry standards for grained
surfaces
K 09: strongly grained (standard of VW)
K 31: smoothly grained (standard of GM)
K 09
Grained surface of VW

A Durable Scratch Resistance Ensures
a High Perceived Quality
An unscratched interior after extensive
use
Creates a high value brand recognition
especially with rental cars or taxis
Influences positively the decision when a
new cars is bought towards the current
brand
Allows a higher selling price when a used
car is sold
Makes it more likely that the customer will
buy a new car from the same brand/OEM

Perfect Long Lasting Scratch
Resistance for Less than 10 EUR
Calculation
Amount of PP/talc used in a standard mid size car: 55 kg
Thereof PP/talc parts with need for antiscratch properties: 15 kg
Amount of TEGOMER ® AntiScratch 100 needed (at 2%): 0.3 kg = < 10 EUR

Ageing is Crucial to Evaluate Additives
for Car Interior Applications
Temperatures in summer in a (closed) car after 1 hour in the sun:
Dashboard:
up to 80 °C
Head room:
up to 70 °C
Foot space:
up to 60 °C
To simulate the conditions in a car we do the following testing:
Scratch resistance test of sample with additives direct after molding
Same test with sample that was aged for 7 days at 80 °C or QUV test

Additive with Long Lasting Effect
Tackiness after UV Irradiation
The PV 1306 test method of VW/Germany
is used to analyze interior automotive parts
based on PP and PP/Talc compounds
regarding their tackiness and migration after
UV irradiation (5 x 96 h).
without Additive
+ 3% TEGOMER ®
AntiScratch 100
Q-Sun Xe-1-B
+ 0.5% fatty
acid amide
+ 3% high molecular

TEGOMER ® AntiScratch 100 does not show any migration and tackiness
in the PV 1306 test. It stays in the bulk phase of plastics compounds and
provides a long lasting scratch resistance.
