摘要:
Rubber compositions reinforced with an iron oxide reinforcement filler having anisotropic properties and articles formed therefrom. The anisotropic properties result from the iron oxide particles being directionally aligned within the matrix of the rubber composition. Such rubber composition include a highly unsaturated diene rubber resulting at least in part from conjugated diene monomers and having a content of such monomers that is greater than 50 mol%. The iron oxide particles may be aligned with the magnetic field lines from a magnet placed in proximity with the rubber composition.

摘要:
The present invention relates to a reversible color changeable coating composition and a preparation method thereof. The plate of the present invention has heat resistance of 400℃ or higher thereby can be used for heating products very stably, and the durability of the plate increases since it has excellent wear resistance, chemical resistance and mechanical properties. In addition, beautiful colors can be obtained by mixing colors in various ways, and being heated can be identified with the naked eye since the color changes when heated.

A method of producing a thermoplastic polymer preform having at least a crystalline finish portion comprising: (i) providing a thermoplastic polymer composition comprising a thermoplastic polymer and at least one reheat rate increasing additive; (ii) forming a preform from the thermoplastic polymer composition, wherein the preform comprises a finish portion and a body portion; and (iii) exposing at least the finish portion of the preform to energy until crystallized.
摘要:
Described herein are aliphatic polyamide compositions including an aliphatic polyamide, glass fiber and, optionally, one or more additives. It was surprisingly found that aliphatic polyamide compositions containing specifically selected glass fibers had similar dielectric performance, and significantly improved mechanical performance, relative to corresponding aliphatic polyamide compositions containing low dielectric glass fiber. At least partially due to the high dielectric performance (low dielectric constant) and significantly improved mechanical performance, the aliphatic polyamide compositions can be advantageously incorporated into mobile electronic device components.
