Materials used in the production of foam insulation
Rubber compounds
NR
Provides flexibility and elasticity. Often used for its excellent vibration mitigation properties.
SBR, NBR, EPDM
Synthetic options offer specific benefits, such as better oil resistance (NBR) or improved weathering resistance (EPDM).
PVC
Polyvinyl chloride plastic is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics.
Foaming agents
Chemical foaming agents
Used to create the cell structure of the foam. Common foaming agents include azodicarbonamide (ADC) or citric acid.
Physical foaming agents
Include gases such as CO2 or nitrogen, which are introduced into the rubber mixture to form bubbles.
Cross-linking agents
Peroxides
Used to cross-link rubber molecules, enhancing the durability and thermal stability of the foam.
Sulfur
Another cross-linking agent that improves the strength and elasticity of rubber.
Fillers
Carbon black
Provides UV protection and enhances the mechanical strength of the foam.
Silicone
Used to improve processing properties and reduce the tendency of the foam to collapse.
Additives
Flame retardants
Essential for improving the fire resistance of the foam. Examples include brominated compounds or phosphate esters.
Antioxidants
Prevent rubber materials from degrading due to oxidation, extending the service life of the insulation material.
Colorants
Pigments and dyes
Added to achieve specific colors, for aesthetic optical purposes or to meet customer requirements.
Adhesives
Contact adhesives
Used to bond the foam to other materials or surfaces.
Pressure sensitive adhesives
Used where easy application and removal is required.
Surface coatings
Protective coatings
Applied to enhance resistance to environmental factors such as UV or moisture.
Decorative coatings
Used to achieve specific surface effects or textures.
Processing equipment
Extruders
Used to shape the foam material into the desired contours.
Moulding equipment
For producing custom shapes and sizes.
Curing ovens
Ensure proper cross-linking and stabilization of the foam material.
