Additional Information: Above values are typical averages obtained from 18 x 2 mm mono layer pipe specimens which are extruded with 97 parts of POLIDAN® T/A-MD and 3 parts of CATALYST CT1 series. These pipe specimens are cured by immersion in 95°C hot water for 6 hours. Storage and Handling - In order to avoid pre-mature crosslinking, the silane crosslinkable compound and the catalyst masterbatch shall be stored separately and mixed only when used. The silane crosslinkable compound shall be used within 6 - 8 hours after bags are opened. - The product shall be stored under the following conditions: -- Closed and unbroken bags -- Ambient temperature not exceeding 40°C -- Indoor in order to avoid direct exposure to sunlight - The product could undergo alterations due to extended period of storage. Solvay Specialty Polymers suggests the product use within six months from the production date printed on the packaging. Solvay Specialty Polymers accepts no liability of any kind in case the above mentioned conditions are not fulfilled. Packaging - POLIDAN® T/A-MD is supplied in 500 kg octabins which contain a single moisture resistant bag or in 25 kg moisture resistant bags placed on 1375 kg pallets. Technical Service - POLIDAN® T/A-MD is part of the Solvay Specialty Polymers POLIDAN® PEX System product range. Solvay Specialty Polymers Technical Service is available to assist customers with further information and advice including the start-up and also for any eventual necessity during the use of the product.

Extrusion Notes: Processing Guidelines - The silane crosslinkable compound POLIDAN® T/A-MD shall be used together with a Solvay Specialty Polymers catalyst masterbatch in the ratio of 97 to 3 parts respectively. Mixing shall be done just before extrusion or during the extrusion process with the use of automatic feeders. POLIDAN® T/A-MD can be processed with modern PE single screw extruders. Curing - The final pipe properties are curing dependent. - Curing can be done in the following ways: -- by immersion in hot water at 90-95°C -- by circulation of hot water inside the pipe at 90-95°C -- by exposure to steam -- in ambient conditions - In all cases curing time depends on the pipe wall thickness, pipe structure and applied curing temperature. Colouring - POLIDAN® compounds and catalyst masterbatches can be used together with good quality PE based colour masterbatches. Solvay Specialty Polymers suggests pre-drying all colour masterbatches prior to use.
