Benefits of PVC foam

PVC foam widespread use in advanced composites is due to its many advantages. The benefits it provides are:

  • High strength and stiffness to weight ratio
  • Process friendly
  • Rot resistance
  • Resistance to solvents and most chemicals
  • Very good fatigue properties
  • Very good thermal insulation
  • Good fire behavior
  • Low water absorption
  • Compatible to many resin systems including epoxy
  • Low resin absorption
  • Durability
  • Ease of adhesion
  • Shock absorbance

When processing PVC foam overlaid by prepreg, great caution shoild be taken to avoid outgasing
