A resin sheet is provided that provide both light-weight properties and mechanical strength using a thermoplastic resin with high deflection temperature under load. The resin sheet is formed from a thermoplastic resin, including: a core layer being a foam resin layer; and skin layers located outward of the core layer as determined along the thickness direction, the core and skin layers forming a continuity. The core layer includes a region A1 and regions A2 each located between the region A1 and the associated skin layer. The regions A2 has a lower average porosity than the region A1, said average porosity being lower than 50%. The thermoplastic resin has a deflection temperature under load not lower than 90° C. The resin sheet has a thickness of 1 to 40 mm. Each skin layer has a thickness of 5 to 50% of the thickness of the resin sheet.

The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.

The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

Apparatus and methods are described including an additional lens (24) made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens (24) is changed such as to conform with a curvature of abase eyeglasses lens (22), without causing a loss of the optical design of the additional lens (24), by heating the additional lens (24) to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (24). Subsequently, the additional lens (24) is adhered to the base eyeglasses lens (22). The optical design of the additional lens (24) is such that, upon being adhered to the base eyeglasses lens (22), the adhered base eyeglasses lens (22) and the additional lens (24) provide a combined lens (20) having a desired optical prescription. Other applications are also described.

The present invention relates to a thermoplastic resin substrate for a curved mirror and a method for preparing the same, and a curved mirror and a head-up display comprising the thermoplastic resin substrate. The preparation method comprises the following steps: A) heating up a mold of an injection molding machine to a temperature in a range of 130-190° C. and closing the mold, B) injecting a molten thermoplastic resin into the cavity of the mold cavity, C) applying a pressure of 300-700 bar to the cavity for a period of 5 or more seconds, D) stopping applying pressure and cooling the mold to a temperature in a range of 60-100° C. within 10-50 seconds, and E) opening the mold and taking out the molded thermoplastic resin substrate, wherein a gap of 0.3-1 mm is left between the parting surfaces of the cavity of the mold prior to applying the pressure to the cavity. The thermoplastic resin substrate according to the present invention features a large size, high dimensional stability, and low surface roughness. It can be used for future augmented reality head-up displays to realize large-area, long-distance projection and high-precision imaging, thereby satisfying the requirements for driving safety and comfort of future automobiles.

Disclosed herein is an apparatus for folding a side extending outward from a cup part in a battery case of a pouch-type secondary battery. The apparatus can include a body having a plate shape, adjacent to the side, and disposed to be elongated in a longitudinal direction of the secondary battery, wherein the body includes, a heating part disposed at one side thereof to heat an inner portion disposed at a relatively inner side of the side, and a pressing part disposed at the other side thereof to press an outer portion disposed at a relatively outer side of the side. When the heating part heats the inner portion, the body rotates to allow the pressing part to press the outer portion.
