In the process of plastic molding, when a certain gas is added or some foaming agent is added, a large amount of air bubbles can be generated, so that the volume of the plastic suddenly expands several times or even seve...
The thermal conductivity of ordinary plastic products is mostly in the range of 0.15 ~ 0.22W / (m, K), while the thermal conductivity of foam plastics is generally in the range of 0.01 ~ 0.04W / (mK), 15 ~ lower than ord...
The chemical principles of core foams can be divided into two categories: Chemical blowing agents are used which liberate gases when heated. Commonly used chemical blowing agents, such as azodicarbonamide, azobisisobutyr...
Polystyrene foam board, also known as foam board, EPS board, is a white object which is heated and formed in a mold by heating expandable polystyrene beads containing volatile liquid foaming agent. It has the characteris...
NASA and European Airbus have recently proposed a foam-filled reinforced strip structure based on the use of sandwich structures and reinforced strip structures for many years, maximizing structural design and manufactur...
The foam board is a branch of plastic foam or plastic sheet. Or it is the result of foaming washing of plastic sheets or slab foam. Use of PMI foam board: 1. Protect the main structure of the building and extend the life...
