We believe a combination of PE and PP would be the best way to create a product with an optimum combination of characteristics for everyday family use. If we were building our Frankenstein grass from the ground up it would probably contain PP as the textured (curly) thatched yarn in the bottom of the product with a combination of structured profile PE yarns creating the blades that make the long straight grass. Having the PP in the thatch of the grass with it’s increased rigidity would help support the longer blades of grass from the bottom of the pile which in turn would increase the products ability to bounce-back and stand up to wear and tear. The PE yarn would allow the grass to be softer to the touch and allow better cold weather resistance to wear and tear.
Just our tuppence-worth. If you’ve got an opinion on this we’d love to hear from you. We’d also always love to hear from anyone working with recycled plastic yarn or finished artificial grass products that are more easily recycled. If this is you please get in touch.
a parting note about Polyethylene…
Polyethylene is manufactured in a variety of grades – C2, C4, C6 and C8 in which the number denominates the number of carbons in the polymer.
When it comes to artificial grass lower grade C2 and C4 are the most commonly used grades of polyethylene. Most of the artificial grass sold in the UK is made from this low-grade polyethylene that is also used to make disposable shopping bags (remember them?) and poor quality cling-film. We recommend either C6 and C8 grade polyethylene in products as this will provide the best material functionality whilst retaining important characteristics such as not being too stiff, shiny or soft. Combining the properties of these polymers creates products that ultimately are structured to have the best product life-cycle possible.
The main product we currently recommend for domestic use (TurfWorks Majestic) is manufactured from a specialist polymer mLLDPE C6 which stands for metallocene linear low density polyethylene C6 which has many of the characteristics, functionality and durability of higher grade C8 polyethylene but forms a softer extrusion which in turn makes the grass product slightly softer to touch.
