LOPROTEX LPX

LOPROTEX LPX is the excellent latex concentrate preserved with ammonia. The special processed of this product enable it to have very low non-rubber and ultra low extractable protein. This high purity latex concentrate has been developed to suit most application especially in dipping industries. LOPROTEX LPX can be used in all vulcanizing system and it provides excellent stability and good dry film physical properties when compared to other types of deproteinised NR latex.

APPLICATION
LPX is the ultra low extractable and antigenic protein and low non-rubber latex concentrate. It is suitable for all latex applications especially those that need to meet stringent requirement on low residual extractable and antigenic protein and low non-rubber solid in the finished products.

Typical formulation of LOPROTEX LPX in post-vulcanised system is as follows
LOPROTEX LPX 100 DRC
10%  potassium hydroxide 0.1 - 0.3 phr
10%  potassium laurate 0.1 - 0.2 phr
50%  sulphur dispersion 0.7 - 1.2 phr

PACKING
LOPROTEX LPX is packed in non-returnable metal drums of net weight 205kg or delivered in bulk tank.

STORAGE
It is recommended to store this product under shade without exposure to direct sunlight at temperature below 35°C but not in freezing condition. This will prevent the product from creaming and if this happen, stirring is required to re-disperse the cream.
Properly stored product should have a shelf life of 6 -12 months. Longer storage than this period is not recommended.
LOPROTEX LPX, the EP will increase gradually during storage. It is recommended that usage should be within 3 months from the production date. Thereafter, longer than 1 min. post leaching is necessary to achieve required EP in the finished products.
