Frequently Asked Questions: What is SBR? SBR
stands for Styrene Budadine Rubber. It
is manufactured as a liquid and poured into molds, generally for the
automotive industry. We utilize recycled SBR from tires, hoses and windshield
wipers. SBR is utilized in the
Base Mat of the Vitriturf Playground System.
We offer it as shreds rather than as granules.
The shreds make the system more resilient. What is EPDM? EPDM
stands for Ethyl Propolyne Dione Monomer.
It is manufactured as a liquid and then oven dried in sheet form.
The sheets for our industry are typically 18” wide by 3’ long.
Because it is produced as a liquid, it may be tinted to certain colors.
Some pigments hold up well under the Ultra Violet, but others do not
such as primary red. The slabs are
then granulated to the desired size. The size can vary from .5 mm to 4mm.
We utilize .5 to 3mm. The
EPDM is utilized in our wearing course. We
only use virgin EPDM rather than recycled EPDM.
The recycled EPDM looses it characteristics and deteriorates much more
rapidly. What is the
difference between Vitriturf Binder and Vitriturf Aliphatic Binder? The
standard Vitriturf Binder is what the industry calls an aromatic binder.
This is the binder most of our competitors use for both their base mat
and wearing course. Aromatic
binders are good, but they do not offer much Ultra Violet protection.
Aromatic
binders amber, so when they are mixed with certain colors such as grey, tan,
purple and eggshell they cast a yellow appearance.
It is fine to utilize aromatic binders in the base mat and colors that
will not exhibit much ambering such as red, black and green.
Because aromatic binders do not offer much ultraviolet protection they
chalk over time and eventually break down.
Once they breakdown they do not hold the granules together and the
system will fail. Aliphatic
binders will provide what the aromatic binder cannot.
Aliphatic binders are ultraviolet resistant so the granules remain
color fast. Because the aliphatic
binder is ultra violet resistant it will not breakdown as fast and will offer
a longer life to the system. Because
of our introduction of the aliphatic binder to the poured in place industry,
this binder is now being specified throughout the United States
as the preferred binder. What are
acceptable substrates? The
multipurpose system may be applied over concrete, asphalt or masonry.
The playground system may be applied over concrete, asphalt, masonry or
95% compacted stone. The problem
with stone is the compaction rate. If
the stone is not properly compacted it will move after a period of time and
cause a hollow spot in the Vitriturf System.Our new TK System allows for installation directly over hard pan dirt or grass. Please click on TK System
for
more information or contact our office at 631.231.1300 x22 In what
temperatures may the Vitriturf System be applied? Temperature
affects the system in workability of the materials and the dry time.
We prefer to install the system in temperatures above 40 F.
The lower the temperature, the thicker the viscosity of the binder, the
harder it is to trowel and longer to dry.
The dry time of the binder is dependent on two variables: temperature
and humidity. The higher the
temperature and humidity the faster it will dry.
If you have high temperatures but low humidity, the material will not
dry as fast. This is because the
urethane is moisture cured. When can we use
the playground after the system is installed? In
most cases the playground can be opened 24 hours after the installation of the
system. We prefer 48 hours for
sufficient curing of the material. One
must consider the time of year and the temperature and humidity before
allowing usage of the play area. Is Vitriturf
toxic? Vitriturf
is not “toxic." Our
urethanes are properly labeled for warnings.
There is no smell associated with our product and they are 100% solids
that means there is no solvent in the product.
The only smells emitted during a project would be a rubber smell or
diesel fuel. The diesel fuel is
utilized as a lubricant for troweling and cleaning of the mixer. How is the
system terminated? The
edge of the Vitriturf System should not
be left exposed. In situations where an existing edge does not exist a
“keyway” should be provided at the termination point.
A “keyway” is a saw cut trench with dimensions of 1/2” wide by
1/2” deep.
