The present invention discloses an encapsulation composition, an encapsulation film including the encapsulation composition, and an electronic device module. The encapsulation composition includes a polymer matrix, a tackifier and a free radical initiator. Based on 100 parts by weight of the polymer matrix, the polymer matrix includes 5 to 100 parts by weight of highly branched polyethylene (P1), 0 to 95 parts by weight of an ethylene-&#x3b1;-olefin copolymer, and 0 to 70 parts by weight of an ethylene-polar monomer copolymer. The highly branched polyethylene (P1) is an ethylene homopolymer having a branch structure and has a degree of branching of not less than 40 branches/1,000 carbon atoms. A density of the ethylene-&#x3b1;-olefin copolymer is not higher than 0.91 g/cm. The encapsulation composition provided by the present invention has good volume resistivity, aging resistance, processability and low cost.

Encapsulating composition and encapsulating film comprising same and electronic component assembly

The present invention discloses a rubber composition, a processing method for obtaining the rubber composition, and application of the composition in processing of flame-retardant products. The rubber composition includes a rubber matrix and essential components. The rubber matrix includes a branched polyethylene with a content represented as A, in which 0&#x3c;A&#x2264;100, and an EPM and an EPDM with a total content represented as B, in which 0&#x2264;B&#x3c;100. The essential components include 1.5 to 10 parts of a crosslinking agent and 40 to 300 parts of a flame-retardant agent. The rubber composition can be applied to production of flame-retardant products, such as flame-retardant cable, flame-retardant cool air hose for automobile, flame-retardant sealing strip, high-temperature-resistant flame-retardant conveyor belt, and flame-retardant waterproof coil. The products have good flame-retardant effects and mechanical properties.
