Automotive Applications of PP/talc with

High Importance of Scratch Resistance

Dashboards

Interior door panels

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“)

The quality impression of the interior determines the quality

impression of the total car!

Door Panels are a Typical Application

for Antiscratch Additives

K 09

Grained surface of VW

moulded in our lab

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)

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

In-house capabilities

Erichsen equipment for evaluation of scratch resistance

Moulding devices for grained surfaces (e.g. K09 & K31)

Other automotive norms such as Crockmaster or Multifinger scratch tester

available

We offer our technical equipment and our knowledge in evaluating the

scratch resistance of compounds modified with our additives. This can

be PP/talc, PP/wollastonite or other polymers.

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

Q-Sun Xe-1-B

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).

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.
