What‘s plastics “Foam” and “SOFTLON”?

It is a type of plastic product in which air bubbles are dispersed to make it porous. It is also called “foam,” a collection of small “bubbles.” A foam contains a lot of air in it and thus is light weight and has excellent property for cushioning and thermal insulation. We can see products made of foam at home, such as a washing sponge in the kitchen and a cushioning material for chairs and pillows

It is a structure of foam where the inner bubbles are independent, not connected to each other. When the inner bubbles are connected to each other, it is a structure called “open cell.” Closed cells do not easily release the inner air. So, they moderately bounce, quickly recover their original shape, absorb no water, and resist water.

Emitting an electron beam on a polymer material can break some molecular bonds and generate active spots (radicals). irradiation crosslinking is a technique to bond these active spots to each other. Compared to chemically cross-linked products, irradiation cross-linked products are more uniform and stable. The advantages include a soft and smooth surface, and good color development without using a crosslinking agent.
