Rubbaflex® sg is a wet pour product made up of larger 1-4mm EPDM granules combined with a one-component polyurethane binder. It’s most common uses are in the construction of children’s play areas, golf path construction and occasionally splash parks. Because of the larger granule size, it is more porous than Rubbaflex fg and has to be installed at a greater depth than Rubbaflex fg.
As with all Rubbaflex products, numerous colours are available and can be blended together to give an infinite number of colour schemes.
Characteristic and benefits; soft, colourful, porous, impact absorbent, seamless
Typical Uses; Golf paths, Playground flooring, boat decks, balcony’s,
Rubbaflex sg (Standard grade) EPDM granules are 1-4mm is size. There are made with specialist pigments and UV stabilisers. Flexflooring source these granules from a number of manufacturers in the UK and Europe. Not all granules are of the same quality, but through experience Flexflooring source from tried and trusted producers. This grade of EPDM is commonly used in the construction of children’s play areas, and golf paths. Either laid at 15 – 20mm on an asphalt or concrete sub base, or onto an SBR base rubber (laid at 25mm) layer which will sit on an compacted stone base.
Flexflooring use a selection of polyurethane binders sourced from around Europe.
There are two classes of polyurethane binders;
Aliphatic binders, are a non yellowing, UV stable binder which dramatically reduces colour fade. It is a class of isocyanate used in the manufacture of light stable coatings, more expensive than…
Aromatic binders, commonly used in the construction of playgrounds, but will cause colours to fade in UV light, as it is a class of isocyanate which is sensitive to Oxidisation and prone to degradation in direct sunlight.
It is far more common to install Rubbaflex SG with an aromatic resin, due to the installation depth. With black this makes no different, but one must be aware that other colours will yellow/golden.
