Ladies and Gentlemen,
When preparing for this presentation we were searching for a good title. We choose the displayed title: Stamylan P, the right choice with impact. Let me try and explain as an introduction why we have made this choice.

5. Trends in PP Industry
Historically, PP Innovation focussed on catalyst and technology developments
These “technological” developments are matched quicker in increasing competitive PP environment.
PP Producers: Forced to be cost driven and to optimise operating efficiency:
Increase of minimum production run length
Less flexibility to produce ‘specialties’
“Special” products become quicker and quicker commodities.
Many interchangeable PP grades available.
Differentiation possibilities based on PP grade performance are decreasing

6. A new type of PP innovation…
Catalyst & technology developments are not anymore THE “differentiators” in PP business.
Future PP Innovation will focus also new logistical concepts, organisational flexibility, internet development…
One specific new type of PP innovation concentrates on a multi-functional PP product portfolio:
Higher market coverage with less grades
Multi-functionality in mono and multi applications
Excellent grade “processability” and “consistency”
“Stable” portfolio for customers

Sabic developed a PP-B specially for this application. The development criteria were:
Very high impact combined with a high stiffness (out of the normal range)
Good processability
MFI (I2) = 0.3 dg/min.
The difficulty is that high impact together with high E modulus is difficult. (EXPLAIN GRAPH).
This slide showes the outcome of this development. This PP-B is wide out of the normal range of existing materials (EXPLAIN GRAPH).

19. Conclusions PP Industry trends lead to a new type of PP innovation.
One new type of PP innovation targets a multi-functional product portfolio leading to:
Reduction of number of PP grades
Ultimate level of product processability & consistency
Increase of “multi-application” use
Decomplexation at PP producers and convertors (lower costs)
“Stable” grade portfolio for customers
