Strucell P is a cross-linked rigid structural PVC foam material. Strucell P, as a close cell foam, based on vinyl polymer, modified with the throughout Aramids link. It is the compounding chemical material based on PVC and PUR. It is said as the cross-linked PVC foam core, in the international practice. Strucell P can be used as the core material in the sandwich structure. Properties Strucell P series foam is closed cell cross linked regid PVC foam, with excellent specific modulus and strength. Strucell P foam core have outstanding fatigue properties, inpact resistance and low water absorption. It also has good insulation properties. Strucell P foam have both the good size stability and machinability, compatible with various sandwich structure processing methods, compatible with various resin systems. It is the ideal core material for te light weight high strength sandwich composite core material. The processing temperture ranges from -240ºC to +100ºC, the long term operation temperature ranges from -240ºC to +80ºC Strucell P foam have good water resistance and not rotten. Strucell P foam have good fire resistance. Strucell P series foam products can widely be used in wind energy, marine, sports, railway and aerospace industries. The density ranges 45-250 kg/m3

Surface treatment: The selection of the appropriate post-processing technology will affect your product from all aspects such as the performance, cost and production efficiency. We have an advanced foam post-processing system and we will help you select the proper processing technologies such as cutting, grooving, perforation and so on. Depending on different lamination processes and requirements of surface curvature, we provide 6 kinds of foam cores (as shown in the following) with optimizing the amount of glue absorption:
There is no other post- processing. If you want curved surface, you can get it upon treating the flat plate by thermoforming.
Suitable for hand lay-up, compression molding and other processes of the flat plate with sandwich structure.
Small squares are formed by cutting on one side of the flat plate in both directions of length and width with gluing fiberglass mesh on the other side.
Suitable for products with curved surfaces.
Cut both sides of the core material to the extent 55-60% of the thickness and the cutting positions are staggered. The amount of resin absorption is much less than that of scrim foam.
Suitable for the application with small curvature.
Perforate holes with diameter of about 2 mm on plates. You can adjust the diameter of holes according to the thickness and density of the core material. Trapped air formed in the process of lamination can be removed from the bottom of the core material by perforating holes. Also, the resins can flow from one side of the core material to the other side.
Suitable for hand lay-up, vacuum infusion, compression molding process to improve the adhesive strength.
Guide slots are set on the plate surface. Guide slots can be disposed in length or width direction on one side or both sides of the plate. The groove(s) can work as the flow path of resins and can remove the trapped air when using the resin vacuum infusion lamination process.
Suitable for vacuum infusion and compression molding process to produce products with large area.
Slotted Perforated Plate
20mm. On the basis of slotted plates, perforate holes with a diameter of 2 mm in the slots that the spacing between every two is 20 mm in the length or the width direction of the plate.
It has features of the two above core materials, suitable for vacuum infusion, compression molding and vacuum bagging process to produce large-scale products.
