The foam sheet of the present invention is biodegradable, can be recycled, has good processability, is lightweight, exhibits excellent appearance, has practically satisfactory heat resistance and is more acceptable to the environment. There is provided a crosslinked biodegradable resin continuous foam sheet comprising biodegradable resin, and has an expansion rate of about 1.5 to about 50 and a gel fraction of about 3% or more. There is further provided a method for producing the foam sheet comprising the steps of: (1) preparing a sheet from a resin composition comprising a biodegradable resin, a thermal decomposable blowing agent, and a crosslinking promoter; (2) irradiating the resulting sheet with an ionizing radiation to crosslink the resin composition; and (3) subjecting the crosslinked sheet to heat treatment to continuously prepare a crosslinked foam sheet. Thus, the foam sheet of the present invention can be used in a wide range of practical applications such as, for example, interior materials for an automobile, thermal insulators such as a pipe covering, cushioning materials such as a tape core and the like.

A polyolefinic resin is combined with a (meth)acrylic polyfunctional monomer compound having an aromatic ring, an alicyclic ring or a heterocyclic ring nearly in the center of its chemical formula, and a pyrolyzable chemical foaming agent to give a curable and foamable polyolefinic resin composition. The composition is shaped into a sheet, then cured and foamed into a sheet foam. The cured foam of polyolefinic resin has a curing degree of from 10 to 70%, and has the advantages of good heat resistance, good workability and shapability, and good pressure resistance.

An automobile door comprises a cavity defining door body and a shock absorber consisting of a plurality of tiered foam main members, and resin foam auxiliary members disposed between and connecting the main members to form chambers open transverse to the direction along which the main members are tiered.

Automobile door

An automobile door comprises a cavity-defining door body, and shock absorber consisting of a plurality of foamed-resin tubes disposed in the cavity such that the tubes are axially in parallel and are aligned in the thickness direction of the door body.

A molding laminate includes a cross-linked polyolefin resin foam, a facing material laminated on the foam, and an adhesive layer adhering the foam and the facing material to each other. The adhesive layer comprises a water-based adhesive material cured by a curing agent, and is baked in advance of the interlaminal adhesion process onto the cross-linked polyolefin resin foam and/or the facing material.
