Abstract
Official abstract text for this publication.
Curable polyolefin composition comprising: (A) polyolefin having at least two aliphatic unsaturated bonds per molecule; (B) wax with melting point of 30 to 100° C.; (C) organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; and (D) catalytic amount of hydrosilylation reaction catalyst, wherein content of component (A) is 20 to 80 mass %, content of component (B) is 10 to 75 mass %, and content of component (C) is 1 to 20 mass %, each based on the total mass of components (A) to (D). The composition can be cured to form a cured product capable of storing and releasing thermal energy, and preventing the wax leaking/pumping out during heat cycling.

1 . A curable polyolefin composition comprising: (A) a polyolefin having at least two aliphatic unsaturated bonds per molecule; (B) a wax with a melting point of 30 to 100° C.; (C) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; and (D) a catalytic amount of a hydrosilylation reaction catalyst, wherein a content of component (A) is 20 to 80 mass %, a content of component (B) is 10 to 75 mass %, and a content of component (C) is 1 to 20 mass %, each based on a total mass of components (A) to (D). 2 . The curable polyolefin composition according to claim 1 , wherein component (A) is a polybutadiene. 3 . The curable polyolefin composition according to claim 1 , wherein component (B) is a wax selected from a paraffin wax, a microcrystalline wax, or a polyethylene wax. 4 . The curable polyolefin composition according to claim 1 , further comprising: (E) at least one inorganic filler. 5 . The curable polyolefin composition according to claim 4 , wherein component (E) is at least one inorganic filler selected from a flame retardant filler or a thermal conductive filler. 6 . The curable polyolefin composition according to claim 4 , wherein a content of component (E) is not more than 50 mass % of the composition. 7 . A cured product obtained by curing the curable polyolefin composition according to claim 1 .
