1 Production of compounds in high and low density polyethylene for extrusion and blowmoulding

2 Our company Pebo belongs to System Group. System Group was founded in 1979 and after 30 years of activity, it is a leading supplier of complete and innovative polyethylene and polypropylene channelling systems in more than 30 countries. The Group itself has 12 production sites and commercial offices, primarily in Italy but also abroad with over 500 employees. Founded in 1987 and located in Tuscany, Pebo is specialized in producing high and low density polyethylene compounds, using either virgin raw materials or selected industrial waste with end market extrusion, injection and blow moulding. Located in a small village called Sestino (AR), the company employs operators, technicians and office staff for a total of 30 people in a production site of sq.m. Over the recent years, the System Group invested significantly to guarantee Pebo a state of the art production site: three top class regrinding lines a washing line a grinding line and a high tech lab to enable precise control of incoming materials as well as the finished product. On top of this, experience, reliability and quality makes the company dynamic and responsive to the market evolution. 2

3 Our production cycle The raw material used for the production of the recycled polyethylene granules have the following origin: fig. 2 a) Industrial plastic waste materials fig.1 b) Post-consumer recycled materials (ref. p.6) fig. 2 c) Off-grade virgin polyethylene fig. 3 d) Chemical additives fig. 1 fig Sampling 2. Ground material infeed control silos silos mixer 3. Ground material selection and storage 4. Mixing additives mixer silos extruder 5. Additive dosing and extrusion 6. Granule control and storage silos 7. Control and packing 8. Outcoming coumpounds control and delivery of its certification 3

4 Our lab Pebo lab represents the main advantage. Actually, tests are carried out on various plastic materials using sophisticated and technologically advanced equipment which approves incoming raw material quality and guarantee quality throughout the production chain up to customer deliveries. High quality in Pebo compounding is also granted thanks to the correct mix of raw materials to use in the production process. Laboratory TESTS TYPE OF TEST M.F.I (g/10min ) Density (g/cm 3 ) D.S.C. (min) O.I.T. (min ) Water content (ppm) TGA - Carbon black content (%) TGA - Inorganic filler content (%) FITR certifies the fluidity of the material certifies the density. The products can then be classified as either high or low density used to identify any contamination by other materials: for example, if there are any polypropylene components resistance to oxidation; aging to check for the presence of water. Water is considered a pollutant carbon black gives the pipe its colour and renders it resistant to UV rays to check for the presence of these contaminants. to check for the presence of contaminants of plastic origin 4

5 Lab machinery FTIR machinery It is used for raw material identification tests, qualitative analysis of plastics, analysis of contaminant. DSC Differential Scanning Calorimetry It determines transition temperatures and enthalpy changes in solids and liquids under controlled temperature change. Typical applications of DSC are: melting-crystalization, phase diagrams, crystallinity of semi-crystalline materials, specific heat capacity, oxidative stability, decomposition onset and compatibility. KARL FISCHER COULOMETER It is suited for water content determinations in raw materials (final products) MELT FLOW MODULAR LINE It is used to calculate the Melt flow index of materials both at the start and at the end of production process. Melt flow index or MFI is a measure of the ease of flow of the melt of a thermoplastic polymer. The method is described in the similar standards ASTM D1238 and ISO TGA - THERMOGRAVIMETRIC ANALYSIS Is a thermal analysis method used to obtain information about material s thermal stability and composition. A thermobalance is used to measure the mass change of a sample as a function of temperature or time, under a defined and controlled environment with respect to heating rate, gas atmosphere, flow rate, crucible type 5

6 Material delivery options and certificates Compounds can be delivered in three ways to match customer needs: - 25 kg bags on 110x130 cm pallets kg Big Bags on 110x130 cm pallets - 25,000 kg bulk Lab analysis is carried out on material prior to despatch and certificates of quality are delivered together with the shipping documentation. All products are certified by : - Bureau Veritas certification - Company Quality System certification UNI EN ISO 9001:2008. Pebo also recycles waste plastic materials from industrial processes (pre-consumer) such as injection mouiding, extrusion and blow moulding in general, and from post-consumer, in particular: pipes - sheets - drums - tanks.
