Provided is a resin material capable of effectively enhancing insulation properties, adhesiveness and long-term insulation reliability. The resin material according to the present invention contains first inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.90 or less, second inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.95 or more, third inorganic particles having an average aspect ratio of more than 2, and a binder resin.

Resin material, method for producing resin material, and laminate

A shock-absorbing sheet comprises a foamed resin layer having a thickness of 200 &#x3bc;m or less, a void ratio (P) of a plane directional cross section at a thickness of 0.1 T, a void ratio (P) of a plane directional cross section at a thickness of 0.5 T, and a void ratio (P) of a plane directional cross section at a thickness of 0.9 T from one surface of the foamed resin layer each ranging from 10 to 70 area %; and the standard deviation (P&#x3c3;) for an average void ratio found from the void ratio (P), the void ratio (P) and the void ratio (P) ranging from 1.0 to 20.

Shock-absorbing sheet

The foamable composition according to the present invention comprises a copolymer of ethylene, an &#x3b1;-olefin and a non-conjugated diene, a blowing agent, a crosslinking agent, a catalyst and a reaction suppressor, wherein in the foamable composition, the storage elastic modulus at 23&#xb0; C. as measured by a viscoelasticity measuring apparatus is 2&#xd7;10Pa or lower, and the storage elastic modulus after the foamable composition is held at 115&#xb0; C. for 200 seconds is 5&#xd7;10Pa or higher; thereby, a foam body having a low expansion ratio, a low compression strength and a high cushioning property can be produced.

Foamable composition

The present invention aims to provide a light control material capable of optionally controlling the light transmittance in an arbitrary wavelength range among a wide wavelength range, and a light control film formed by using the light control material.

Light control material and light control film
