Polygrene-PP macrofibres

---

Polygrene-Thermoplastics are produced by melt-processing Versarien’s nanomaterials (e.g. Nanene and Hexotene) along with other additives and virgin polymer pellets using processes such as twin-screw extrusion to manufacture compounds and masterbatches in pellet or filament form.

Versarien’s materials testing either takes place through its R&D teams based at the Graphene Engineering Innovation Centre (GEIC), University of Manchester and at the Cambridge Graphene Centre (CGC), University of Cambridge or through Versarien funded researchers based at WMG, University of Warwick. A number of tests are also performed by independent test laboratories or performed entirely by our clients.

Polypropylene (PP) is a thermoplastic used in a number of construction applications (geopolymer mesh, micro/macrofibres). Macrofibres are generally used to minimise and/or eliminate both plastic and drying shrinkage cracking. They can be used to replace rebar and welded wire reinforcement and provide equal or better performance when the proper dosage is used. Macrofibres provide all the benefits of microfibres, in addition to increased durability, flexural toughness, and resistance to impact and abrasion.

Versarien have developed graphene enhanced PP macrofibres that are superior to standard virgin PP macrofibers with 100% higher elastic modulus (stiffness). 

The benefits of Polygrene-PP macrofibres include:

• Increased flexural strengths
• Improved tensile properties of concrete
• Increased durability
• Reduced CO2 and cost (less material, removal of steel rebar)
• Reduced material (thinner slab, less cover, reduced reinforcement)
