The present invention relates to two-dimensional and three-dimensional shaped parts and composite materials made of popcorn and synthetic and/or natural binding agents which are cured in automatic moulding machines or similar pressing installations by means of radio wave technology or microwaves. By means of these technologies, light-weight, two-dimensional and three-dimensional shaped parts and composite materials can be produced for packaging, as interior and exterior parts (for example in automobile and mobile-home construction), shock absorbers, space-dividing elements, furniture, consumer goods, for the building trade of for heat insulation.

A crosslinked polyolefin separator having a ratio (A/B) of storage modulus G′ (A) to loss modulus G″ (B) of 2 or more, at a range of the frequency of the crosslinked polyolefin separator of 1 rad/s or less, in the frequency-loss/storage modulus curve. The crosslinked polyolefin separator is controlled to have a high ratio of storage modulus to loss modulus, and thus maintains its elasticity even at high temperature. Therefore, it is possible to provide a separator having improved safety.

An optical forming device includes a light source to emit light for causing liquid photocurable resin to undergo curing and an optical modulator to modulate the light for causing the liquid photocurable resin to undergo curing in a pattern based on a shape of a three-dimensional object, and irradiate the liquid photocurable resin with the modulated light. The optical modulator includes a liquid crystal device to modulate the light for causing the liquid photocurable resin to undergo curing in the pattern, and emit the modulated light as linearly polarized light and an optical retardation device to impart a phase difference to the linearly polarized light emitted from the liquid crystal device, and emit the light imparted with the phase difference.
