The present invention relates to a transparent member for an automotive interior part. In one embodiment, the transparent member for the automotive interior part includes: a light source; an optical pattern layer formed over the light source; and a first light-transmitting skin layer formed on the optical pattern layer and including about 1 part by weight to about 25 parts of a first inorganic filler dispersed in 100 parts by weight of a first transparent resin matrix, wherein the first inorganic filler includes spherical calcium carbonate (CaCO.sub.3).

A curable polyurethane type resin composition which is applicable for a sealing material for an electrical device used in a vehicle, enhances a hydrolysis resistance of a cured substance and can suppress a decrease in physical properties in high temperature and high moisture environments. The curable polyurethane type resin composition contains castor oil-type polyol, polyisocyanate, and epoxidized acrylic polymer. The electrical device has electrical components covered with a sealing material consisting of a cured substance of the curable polyurethane-type resin composition.

Disclosed are a method for preparing a sound-absorbing member and a sound-absorbing member. The method for preparing a sound-absorbing member includes: providing non-foaming sound-absorbing material powder and a foaming material; uniformly mixing the non-foaming sound-absorbing material powder with the foaming material and adding an auxiliary to form a sound-absorbing mixture; and foaming the sound-absorbing mixture to form foam with cells, wherein the non-foaming sound-absorbing material powder adheres to a surface and the cells of the foam. The foamed sound-absorbing material powder and the foam constitute a sound-absorbing member.

Disclosed are bowing agent compositions, foamable compositions, foams, foaming methods and/or foamed articles comprising one or more C2 to C6 fluoroalkenes, more preferably one or more C3 to C5 fluoroalkenes, and even more preferably one or more compounds having Formula I as follows:

XCF.sub.zR.sub.3-z (I)

Where X is a C.sub.1, C.sub.2, C.sub.3, C.sub.4, or C.sub.5 unsaturated, substituted or unsubstituted radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3, it generally being preferred that the fluoroalkene of the present invention was at least four (4) halogen substituents, at least three of which are F and even more preferably none of which are Br.

Pellets, beads, particles, or other pieces of a thermoplastic elastomer having a maximum size in at least one dimension of 10 mm or less (collectively, pellets) are infused with a supercritical fluid in a pressurized container, then rapidly depressurized and heated either by immersion in a heated fluid or with infrared or microwave radiation to foam the pellets The pellets are prepared with at least two different densities. Pellets with different densities, thermoplastic elastomer compositions, or foam response rates are placed in different areas of a mold. The mold is filled with pellets, then the pellets are molded into a part. The part has areas of different density as a result of the placement of pellets of different density.
