Backside

Structural PVC Foam Core China Professional Environmental PVC Foam for Sandwich Panel
PVC foam, with unique closed cell and cross linked structure, has good properties of high stiffness, strength to weight ratio,superior toughness, low water absorption and excellent resistance to chemicals. the fine cell structure gives a good bonding surface. It is compatible with unsaturated polyester resin, epoxy resin, vinyl ester resin etc, and widely used in the applications of wind energy, aerospace, marine, automobile, train, sports goods and so on.
We will suggest different types according to your application.

Surface finishing

Plain Sheet

If possible, using a plain sheet is the most effective way to utilize a core with regards to material properties. However, plain materials usually do not fit manufacturing processes or applications without machining (adaptation). In the machining or finishing process, a core material starts off as a plain sheet before it is perforated, grooved, slitted or whatever is needed to make it as functional as possible for the end user’s application or process.

Perforations Sheet

When installing large sheets of rigid core, it is important there is no air trapped under the core. To avoid having air trapped between the core and the laminate, small perforations or grooves are often added symmetrically to the core. This technique is commonly used when
doing hand lay-up, vacuum bagging or when using core bedding adhesives. In an infusion process, the perforations will transfer resin from one side of the core to the other – ensuring both sides are wetted out and avoiding trapped air as well. Depending on the process method and materials involved, different kinds of perforated sheets are available to fit both size and orientation.

Grooved and perforated Sheet

When vacuum infusion was first introduced, it often incorporated a separate infusion medium on the surface of the laminate. However, it soon became apparent that the core itself, if grooved and perforated properly, could act as this infusion medium. There are a variety of options to choose from, allowing the user to pick which is most suitable for the process/application.
The various options for grooves and perforations can be successfully combined with formable options such as grid-scored material
