. PVC plastic artificial marble plate sheet board production line extrusion machine plant making machine electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± degree.

In the production of PVC foams, physical mixing is generally performed in the mixer in the first stages. In a more advanced method, turbo mixers are used to generate frictional heat with the high rotational speed of paddles. As the PVC powder heats up, the additives find the opportunity to penetrate into the particle surface. The heated powder is then cooled down and stored. This process is generally conceivable for most PVC products.

Компания Unifoam, одна из дочерних компаний промышленной группы Vispar, была создана в году для производства полимерных листов. Uniform является одним из ведущих производителей пенополистирольных плит в Иране и на Ближнем Востоке. Мы производим тисненые, ламинированные и однослойные ПВХ листы.

As one of the five most consumed polymers in the world, PVC cannot be processed in pure form and typically several batches of additives must be added. These additives include thermal stabilizers, internal and external lubricants, processing aids, impact modifiers, etc. which are selected based on required properties and application site. In the case of PVC foam, a foaming agent, as well as a melt viscosity controller agent, is required as an additive to control the foam structure.
