Gurit PVC 80 is a structural foam core material used in composite sandwich structures. It is a closed-cell, rigid PVC foam that is lightweight, durable, and provides excellent mechanical properties. The foam has a nominal density of 80 kg/m³ (5 lb/ft³) and is compatible with polyester, vinyl ester, and epoxy resin systems.

Some of the key features and benefits of Gurit PVC 80 include:

• High strength-to-weight ratio: Gurit PVC 80 offers excellent mechanical properties and stiffness while remaining lightweight, making it a popular choice for a variety of applications in the marine, transportation, and wind energy industries.

• Good dimensional stability: The foam has low thermal expansion and contraction coefficients, which helps to maintain the dimensional stability of composite sandwich structures under varying temperatures and environments.

• Easy to work with: Gurit PVC 80 is easy to handle, cut, and shape, and can be bonded to a variety of skins and other materials using a range of adhesives.

• Good fire resistance: The foam is inherently flame retardant and meets relevant fire safety standards such as DIN 4102 and ASTM E84.

Gurit PVC 80 is available in a range of thicknesses and sizes to suit different applications, and can be supplied in sheet or block form. The foam can be processed using various techniques such as hand lay-up, resin infusion, and prepreg, and is suitable for a range of applications such as boat building, wind turbine blades, and transportation components.
