摘要:
A thermally conductive filler composition and a resin composition comprising such filler compositions. The filler composition comprises a blend of a boron nitride, a graphite, or a combination thereof, a talc, and optionally a silane. The filler composition can further comprise other filler components including, for example, wollastonite, calcium carbonate, or a combination thereof. The filler compositions can be added to a resin composition to provide a thermally conductive resin such as, for example, a thermally conductive plastic.

The invention relates to a method for producing pan and a pan to be used in a microwave-oven. The method comprises providing a plate (10) of aluminium, with a first major surface (11) being coated with a non-stick material (13) and which first major surface (11) being adapted to form an upwardly facing food-receiving bottom surface of said pan (1), providing a heating member (20) in contact with a second major surface (12), opposite to said first major surface (11), of said plate (10) of aluminium, said heating member (20) being formed of silicone rubber with ferrite particles, arranging said plate (10) of aluminium in an injection moulding tool, and injection moulding a wall (30) of a plastic material onto said plate (10) of aluminium, the wall (30) extending along the perimeter (P) of said plate (10) of aluminium and having an upwardly (Up) and outwardly (Out) directed extension.
摘要:
A thermoformable medical member and heater and method for manufacturing same. A thermoplastic material is converted from a relatively rigid state to a formable state over a narrow temperature range, and, which reverts back to a clinically rigid state within a relatively short period of time, and, which remains in that state even at elevated ambient temperatures.
摘要:
Composite foams having cells containing shape-stabilized phase change material (ss-PCM) particles are described. Composite foams may be made by contacting a plurality of ss-PCM particles and one or more pre-polymer reactants, wherein each ss-PCM particle can form a nucleation site for foam cell generation. The composite foams may be used in regulating the temperature of an article wherein the foam undergoes a phase transition as the surrounding temperature of the article approaches the foam's phase transition temperature. The thermostatic material may exchange heat with the article during the phase transition, resulting in regulation of the temperature of the article. The composite foams may be used as a thermostatic packaging material having a cavity for storing goods.
摘要:
The present disclosure relates to a process for preparing of high thermal conductivity and high heat capacity oriented ultrahigh molecular weight polyethylene (UHMWPE) product. The process includes feeding UHMWPE through rollers to obtain a pre-laminate which is further hot stretched to obtain the oriented UHMWPE product having high thermal conductivity and high heat capacity. The temperature of stretching is maintained below the melt temperature of the UHMWPE throughout the entire process. There is also provided a high thermal conductivity and high heat capacity oriented UHMWPE product prepared by the process of the present disclosure. The oriented UHMWPE product is characterized in the axial thermal conductivity in the range of 70 to 200 W/mK, transverse direction thermal conductivity in the range of 0.022 to 0.045W/mK and heat capacity in the range of 6 to 25 MJ/m 3 K.
摘要:
A valve pin in an injection molding system having an axis and comprising: a first body portion formed into a stem that is comprised of a first selected metal material, the stem comprising an elongated shaft having an upstream end interconnected to an actuator and a downstream end, a second body portion that is formed integrally together with the stem and is comprised of a second selected material different from the first material, the second body portion formed together with and extending distally from the downstream end of the stem into a distal-most extending tip end that is integral or unitary with the stem, the second selected material having a substantially greater degree of resistance to corrosion or wear or abrasion than the first selected material, the distal-most extending tip end being formed into a geometry or configuration that is complementary to a preselected geometry or configuration of a gate such that when the valve pin is moved into a gate closed position the distal-most extending tip end engages an interior surface of the gate to prevent injection fluid from flowing through the gate.
