Intrinsic sustainability of Twaron

in applications

Light Strong Resists heat Endurance

Density 1.44 g/cm3 LOI - 29-37% Decomposition 500 oC 5 times stronger than steel at the same weight. Low maintenance No corrosion

SLIDE 6

Overview of applications

Creating durable tires

Taking the heat in the brakes

Increased lifetime automotive & industrial hoses Longer lasting transmission belts Worry free oil transport When steel fails

Twaron keeps us on-line For vehicles that save lives

SLIDE 7

How does the intrinsic sustainability of Twaron match with tire developments?

Requirements for tire developments: Lower weight tires

Leading to lower rolling resistance
Less CO2 and particulate matter emissions

Less raw materials needed

Requires high strength yarns (per mass unit) Rough comparison on amounts of materials needed for reinforcement:

Twaron: rayon =

1:3

Twaron: PET =

1:2

Steering precision

Requires dimensional stability

What is a “green” tire?

a tire made 100% from natural materials?

A

a tire that results in a better eco performance over the whole life cycle (value chain)?

Where is the biggest environmental impact in the value chain?

Comparison passenger tire carcass

1. compare on function over total value chain

what, how much (raw materials, production)
how long, how well (use phase)

2. Check all effects over the total value chain 3. Focus on the differences 4. Be conservative VERY IMPORTANT 5. Involve from the start and discuss the results with customers and value chain partners: do they agree? Are there other views that need to be taken into account? Is it both environmentally better, and is it a business case?

How? Eco Efficiency Approach

f TUV certified

Customer Benefit Model.

RAW MATERIALS MANU- FACTURING DISTRIBUTION USE PHASE END OF LIFE Twaron/PET Less raw materials: Twaron, PET Rubber equal Less material less transport ecoburden and costs Fuel savings lighter tire, less rolling resistance equal Rayon More raw materials: Rayon Rubber equal More material, more transport ecoburden and costs equal

WHAT AND HOW MUCH HOW LONG, HOW WELL

Benefits for car producers and consumers (drivers, fleet owners) Lower fuel use Better CO2 footprint, less costs! Benefits for tire manufacturers Better CO2 footprint Less costs for raw materials
