Lithene ultra® N4-5000-15MA is a highly viscous, low molecular weight, liquid polybutadiene. It is very low in odour and volatiles and is based on a narrow molecular weight polybutadiene adducted with 15 parts maleic anhydride.
Soft, isocyanate free electrical encapsulants
Adhesion promoter in automotive sealants
Rubber to metal adhesion promoter
Impact modifier for polyester resins
Lithene ultra® N4-5000-15MA is despatched from our UK production plant.
Handling - Lithene ultra® N4-5000-15MA is a highly viscous, liquid polymer. It will flow at ambient temperatures but viscosity will decrease with increasing temperature allowing easier pumping and mixing.
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® N4-5000-15MA 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 and hydrolysis. Further information is available on the datasheet Storage of Lithene Liquid Polybutadienes.
Lithene ultra® N4-5000-15MA is packed in open top 200 litre steel drums containing 188kg and is typically made to order. The minimum order quantity is one pallet (four drums).
