The present invention relates to an aqueous reinforced rubber dispersion comprising: a) 51 to 90 wt-% of base latex polymer particles; and b) 10 to 49 wt-% of reinforcing latex polymer particles comprising structural units of aromatic vinyl monomers and conjugated diene monomers, the reinforcing latex polymer particles having a single glass transition temperature (Tg) from −25° C. to 28° C. as measured by differential scanning calorimetry (DSC), whereby the weight percentages are based on the total weight of polymer particles in the rubber dispersion and the base latex polymer particles have a Tg as measured by DSC that is lower than the Tg of the reinforcing latex particles, to the use of the rubber dispersion for making latex foam, to a method for making latex foam and to an article comprising the latex foam obtained from the rubber dispersion of the present invention.

Disclosed herein is a spark plug comprising an insulative sleeve. A glaze coating is disposed on the exterior surface of the insulative sleeve. The glaze coating comprises a silicate glass, a phosphorous glass, a borosilicate glass, or a combination of the foregoing glasses wherein the glasses are independently modified with a modifier selected from the group consisting of alkali group metals, alkali earth group metals, aluminum, and a combination of two or more of the foregoing modifiers and further wherein the glaze coating has a glass transition temperature (Tg) of 300 to 1000 degrees Celsius.

A thermoplastic polymer composition which is excellent in flexibility, mechanical properties, and moldability, capable of adhering to ceramics, metals, and synthetic resins without a treatment with a primer, and exhibits a high adhesion strength even when exposed to a high temperature environment, and a molded product obtained by using the thermoplastic polymer composition. The thermoplastic polymer composition includes 100 parts by mass of a thermoplastic elastomer (A), 1 to 100 parts by mass of a polyvinyl acetal resin (B), and 0.1 to 300 parts by mass a softener (C). The thermoplastic elastomer (A) is a block copolymer including a polymer block constituted by aromatic vinyl compound units and a polymer block constituted by conjugated diene units or a hydrogenated product of the block copolymer. The polyvinyl acetal resin (B) has a glass transition temperature of 80 to 130° C.

Also disclosed herein is a method for making articles composed of uncross-linked alkyd oligomers.

The invention discloses a heat-insulating glass glaze and a preparation method thereof, and the preparation method of the heat-insulating glass glaze comprises the step of uniformly mixing low-melting-point glass powder, a heat radiation blocking agent, sodium silicate and a heat conduction blocking agent to obtain the heat-insulating glass glaze. The preparation method of the low-melting-point glass powder comprises the following steps: uniformly mixing raw materials, melting at 500-700 DEG C for 10-50 minutes to obtain molten glass, and quenching the molten glass to obtain bulk glass; and crushing the bulk glass, and performing ball milling in a ball mill to obtain the low-melting-point glass powder. The components of the low-melting-point glass powder are adjusted, and a small amount of Li2O, ZrO2, Na2O and NaF are introduced into the low-melting-point glass powder, so that the glass-transition temperature of the low-melting-point glass powder can be reduced to be less than or equal to 300 DEG C, and the visible light transmittance of the transparent heat-insulating coating can be improved to be greater than or equal to 90%.
