Brief introduction of rigid PVC foam board foam

Brief introduction of rigid PVC foam board foam

So-called blowing agent is to make the object material into holes in the material, chemical and physical foaming agent foaming can be divided into three classes of agents and surfactants. Foam has a high surface activity, can effectively reduce the surface tension of the liquid, and liquid film surface electronic double layer arranged and surrounded by air, forming bubbles, and consists of a single bubble bubble. Surface activity of foaming agent is the substance of it. There is no activity on the surface, not foam, and can't be foaming agent, surface activity is foam core. PVC foam board of foaming agent needs to use.

Wooden and plastic foaming agent is exothermic blowing agent, help of plastic and plastic, good effect of crust, forming a rigid surface. More nucleation and TW210, can be a good alternative imported foaming agent, two blowing agent residues when decomposition of azo-free, is environmental protection foaming agent, foam agent using the series of product has good color, dense foam holes uniform, decomposition temperature range, excellent processing properties.

Wood-plastic foam application process: extrusion foaming, the applicable products include PS, PVC sheets, plywood boards.

About general usage of 0.2~0.5%, according to the foaming agent foaming density determines amount of material, depending on the circumstances, may be appropriate to increase or decrease.

Wood-plastic foam odorless, good storage, self extinguishing. Does not decompose at room temperature, but shall be stored in a cool, dry place. Away from the hot steam pipe, the source of fire, avoid direct sunlight. No direct contact with acid and alkali! Storage and mixing areas have good ventilation to avoid inhaling dust, deep skin contact and swallowing.
