Abstract:
The present invention relates to an insert block for a multi cable transit (MCT) packing system. To be more particular, a foaming agent is applied to a penetrating hole on an insert block so that the diameter of the penetrating hole can vary by a foaming agent sheet even without the accumulation of multiple thin sheets. Thus, an insert block for MCT packing system can improve watertightness and dimensional stability and can simplify the manufacturing process. In addition, the insert block can efficiently correspond to various diameters of cables by accumulating the foaming agent sheets in one to three layers. Moreover, the insert block can provide the foaming agent sheets with flame retarding properties by manufacturing the foaming agent sheets through the mixing of expansible graphite, and can efficiently offset the tolerance of the diameter of the foaming agent sheets before and after the insertion of the cable.

Abstract:
PURPOSE: A thermoplastic elastomer composition is provided to be able to improve the abrasion resistance while maintaining the advantage of the thermoplastic elastomer, the elasticity at a room temperature which is the rubber characteristic, and the thermoplasticity at a high temperature. CONSTITUTION: A thermoplastic elastomer composition is manufactured by mixing 100.0 parts by weight of styrene butadiene styrene block copolymer (SBS) and 10-30 parts by weight of silica cake. The silica cake is manufactured by mixing carboxylated styrene butadiene rubber (SBR) latex, silica and metal oxides at a weight ratio of 50:50:10. The carboxylated SBR latex comprises 50-90 parts by weight of monomer with carboxyl group and 10-50 parts by weight of a solvent to 100.0 parts by weight of SBR latex.
