Abstract
The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.
Claims1
A molded foam comprising:
- a tube body;
- and
- a plate-shaped portion joined to an outer side of the tube body, wherein
- an expansion ratio of the molded foam is 2.25 to 3.0,
- the plate-shaped portion has a thickness B, and
- the tube body at a point peripheral to where the plate-shaped portion is joined has a thickness A, wherein one of the following conditions is met:
- (i) a value of the thickness B/the thickness A is 1.47 to 1.95, the thickness A is 1.47 to 1.99 mm, and the thickness B is 2.83 to 2.92 mm;
- (ii) a value of the thickness B/the thickness A is 2.12 to 2.83, the thickness A is 1.53 to 1.96 mm, and the thickness B is 3.91 to 4.41 mm.
