Cycle length, itself there is electric conductivity and the problem such as moulding is single, although and ceramic material insulation, but than great, molding difficulty
Height, is unfavorable for batch production, and its application is also restrained.
Polyphenylene sulfide is a kind of crystallinity, thermoplastic special engineering plastic, and its combination property is superior, has excellent heat-resisting
Property, insulating properties, corrosion resistance, good stability of the dimension etc. advantage, it is especially suitable as the encapsulating plastics of LED lamp, improve
Its heat conductivity is it is critical that a link, and the common method improving polyphenylene sulfide plastic heat conductivity is to blend in the plastic
High conduction powder, however the most generally exist plastic substrate intensity reduce, mechanical property weaken, heat-conducting effect the best
Etc. problem, application is restricted, and along with the development on a large scale of high-power LED lamp, industry is badly in need of improving existing technique, in order to
Obtain the composite of the heat-conducting effect with efficient stable.
