Polymer spinning machine

polypropyleneautomatic

Overview
Agripak technology for the production of structural fibres in PP, related similar materials and bicomponents for concrete reinforcement. Agripak designs and manufactures complete spinning lines for the production of structural plastic macrofibres. These fibres, used to reinforce concrete, are obtained from plastic polymers and represent a modern, sustainable and effective alternative to metal fibres and steel cages.

Advantages of Plastic Fibres in Concrete

• Corrosion resistance: plastic fibres do not rust
• High mechanical strength (compression and tensile)
• Homogeneous distribution within the cement matrix
• Reduction in cracking and permeability
• Savings on steel and cement
• Better workability in shotcrete
• Reduced labour
• No wear on metal mixing parts

Fibre Specifications
