Industry knowledge of foam cutting plotter：

Foam is a polymer material which is based on plastic and contains a large amount of bubbles. Therefore, it can also be said that it is a composite plastic with a gas as a filler. Compared with pure plastic, it has many excellent properties, such as light weight, high specific strength, absorbable impact load, good heat insulation and sound insulation. Therefore, it has been widely used in industries, agriculture, construction, transportation and other fields. Since the advent of foam plastics, its use has become more and more extensive, and its variety has become more and more abundant. Among the most common traditional foams are polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic. Resin (PF) and other varieties.

According to its flexibility, foams can be divided into soft, hard and semi-rigid foams in between. Rigid foam can be used as thermal insulation materials and sound insulation materials, insulation materials for pipes and containers, floating materials and shock-absorbing packaging materials; flexible foams are mainly used as cushioning materials, foam artificial leather and so on. Commonly used foams are polyurethane, polystyrene, polyvinyl chloride, polyethylene, phenolic foam, and the like.
