PVC foam borad manufacturing and applications

Enter Expanded PVC Sheet, or Foamed PVC sheet if you prefer. While the standard PVC WPC free foam board became a popular plastic material during the 1950's, new versions of this plastic material were needed.  All these PVC board need to be made by PVC WPC free foam board extrusion line, the rigid requests are same to the machines manufacturing.

While Rigid PVC sheet and Flexible PVC materials for film were growing in popularity, the range of sizes and limitation of the solid sheet were slowing expansion of the material. A wide range of plastics were developed to fill these niche requirements. One of the new plastic products, based on the demand for more diverse and unique application specific plastics during the 1970's was foam PVC.

PVC Sheet materials are available in a wide range of grades, from Rigid to Expanded Foam. The standard  is  rated for flame retardance, Rather there are several other grades including CPVC and FM-4910 rated for wet bench fabrication.

One of the most interesting grades of PVC Sheet is the 'Clear PVC Sheet', which is a rigid material, and is perfect for applications where you need to see through the material, but still require the chemical resistance or flame retardant rating of the standard Type 1 or Type 2 PVC sheet material.

An opaque White PVC Sheet is also available, it has the same physical properties as the standard Type 1 Rigid PVC Sheet material.

The first 'Expanded' or foamed PVC sheet was then developed and produced. The foamed PVC sheet has been called:

• Flat foamed PVC sheet

• Lightweight closed-cell, free foam, rigid PVC Sheet

• PVC Foam Board

• Extruded PVC Foam Sheet

• as well as several other product names

Where Expanded PVC Foam Is Used

The Foamed PVC Sheet is an excellent material for use in signage, lightweight printed materials, outdoor and digital printed items. Because the base material is PVC, the foam also has many of the same properties as the Type 1 PVC Sheet materials.

This includes:

1) Exceptional Chemical Resistance

2) Fire Retardant to UL-94 V0

3) Very Easy to Bond, Glue or Weld

4) Easy to cut, drill and fabricate

Over the last several years, the continued advancement in the PVC product line has made the Foamed PVC a more useful product. Because it is a rigid foam sheet, it has exceptional thermal and sound insulation properties compared to its weight. The material has very low moisture absorption and is mold and mildew resistant. With the production of large scale flat bed printers, many Expanded PVC Sheet suppliers now offer an enhanced white surface on a 'print grade' Foamed PVC Sheet. This will allow printers to use this material, that has a very smooth surface, as a quality printable substrate. The Foamed PVC sheets yield very high quality work that is stiff and very light weight.
