Technical Informations

Application Advice/Typical Applications

Handling - Lithene ultra® P4-25P is a viscous, liquid polymer. The viscosity of the product will decrease rapidly with increased temperature and the product may be warmed to allow easier processing.

Compatibility - Liquid polybutadienes are generally compatible with most aliphatic and aromatic hydrocarbon solvents. They have limited solubility in alcohols, ketones and esters. Further details are available on request.



Lithene ultra® P4-25P has excellent compatibility with solid rubbers in UV cured flexographic printing plates and acts an a reactive plasticiser.

Incompatiblity with many polar systems makes it suitable for use in the formulation of specialised mould release coatings for closed cell polyurethane foams and as an antifoaming additive for certain solvent based coatings.

Further applications advice is available on request.

Shipping and Storage

Lithene ultra® P4-25P should be stored in cool, dry conditions below +30°C (+86°F). If stored in the original sealed packaging the product has a shelf life of at least 12 months from date of delivery. Product which has been stored for longer than 12 months should be tested before use. Containers which have been opened should be purged with dry nitrogen before resealing to protect the remaining product from oxidative skinning. Further information is available on the datasheet Storage of Lithene Liquid Polybutadienes.

Lithene ultra®P4-25P is packed in bung top 200litre steel drums containing 175kg. The minimum order quantity is one pallet (four drums). 900kg IBCs are also available.
