HEAT SHRINKABLE COMPOUND PRODUCT SPECIFICATION SHEET is pioneer in developing heat shrinkable, heat curable moulding compounds based on polyolefin material containing some specialty chemicals and mould release additives. M.G.POLYBLENDS
Curing material( Peroxide particularly dicumyl peroxide) has not been included in this product ( HSC-T-384) and hence it does not loses its processing as well as electrical properties during storage. That means it can be stored for any period of time. Users have to incorporate peroxide during sheeting of the material on a Two Roll Mill or mix in a mixer prior to use in injection moulding. It offers excellent weathering and other electrical properties required in cable jointing applications. This compound offers antitracking properties in the moulded product. Outstanding properties of this compound makes an excellent choice for the moulding of heat shrinkable Rain Sheds, Cable Breakout Boots and End Caps. The other grades of this antitrackng compound are used to manufacture Heat shrink tubing / Heat shrink tube/heat shrink sleeves for the cable industry.

RECOMMENDED PROCESSING CONDITIONS: •
FOR COMPRESSION MOULDING
1. Shee Sheeti ting ng on on Two Two Roll Roll Mil Mill: l: Compound has to be milled on a two roll mill ( For better mixing and proper rolling of the compound, rolls of the two roll mill should be at 85-90 0 C). Once the Proper band is formed , add approx approx 0.6% of dicumyl dicumyl peroxide peroxide (purity (purity level 98-99%) 98-99%) on the material material and mix mix again properly properly till homogeneously mixed roll sheet is formed. 2.

1.
FOR INJECTION MOULDING Mix 0.6% ( Purity level 98-99%) dicumyl peroxide with this compound ( preferably slightly heated) in a ribbon or similar type of blender. Then these granules can be directly put into the injection moulding machine with heated moulds to make heat shrinkable end caps, breakout boots and rain sheds.
