A roof laminate (10) includes a roof membrane (12, 100, 200, 300) and a protective sheet (14, 114, 214, 314) removably affixed thereto. The surface (20) of the roof membrane (12, 100, 200, 300) can be protected from dirt, scratches and scrapes by a protective sheet (14, 114, 214, 314) which also provides other beneficial attributes that aid an installer. The membrane (12, 100, 200) and the sheet (14, 114, 214) are heat laminated together in the absence of adhesive and tackifiers. Alternatively, the membrane (12, 300) and the sheet (14, 314) are surface treated and then brought into contact with one another in the absence of adhesive and tackifiers. The sheet (14, 114, 214, 314)) may be single layer or include at least a first layer (30) directly secured to a second layer (32). The first layer (30) provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate (10) and so aids the installer in at least one of those respects. The second layer (32) is removably affixed to the roof membrane (12, 100, 200, 300).

A biaxially oriented polyester film having the following physical property is provided: when cooled from the molten state at a cooling rate of 20° C/min, an observed recrystallization temperature is 175° C-200° C. The biaxially oriented polyester film is formed by a thick sheet before bidirectional stretching that is melted and extruded by an extruder and then cooled and formed on a casting roll. The thick sheet before stretching having the following physical property as analyzed by differential scanning calorimetry: a crystallization rate is less than 10%.

Disclosed is a nanosilica-containing thermoplastic hot-melt film having excellent bonding strength, which may be inserted between fabrics to adhere them to each other and may be distributed uniformly on the surfaces of both the fabrics without excessively penetrating into one of the fabrics after melting by heat and pressure during no-sew pressing even if the yarn density of the fabrics is high or low or even if the hole diameter of the fabrics is large or small, thereby increasing the bonding strength between the fabrics.

Disclosed is a low-temperature supercritical foaming process, comprising the following steps: (1) bringing a polyolefin material or a thermoplastic elastomer material into contact with at least one inert gas in a reactor at a pressure higher than atmospheric pressure to drive the gas into the material, the pressure holding temperature of the polyolefin material or thermoplastic elastomer material being lower than the melting temperature of the material by 5-40° C.; (2) reducing the pressure to expand the material so as to produce a primary foamed material, and taking out the primary foamed material; and (3) taking out the primary foamed material and putting same into a tunnel furnace for secondary foaming, the temperature of the tunnel furnace being higher than the melting temperature of the material. Compared with the prior art, the present invention features high production efficiency, energy saving, and improvement of the reactor utilization rate.

The present invention relates to a coated article comprising a partial or complete fluorinated coating on the surface of an article, wherein the coating comprises 5 to 99% by weight of a hydrophobic compound, and 1 to 95% by weight of a fluorinated surface effect agent, both based on the total solids weight of the coating, where the hydrophobic compound is selected from a hydrophobic cyclic or acyclic ester alcohol.
