Our Material
Our products are materials manufactured with a high content of recycled
crumb rubber from tires along with certain plastic resins. Our materials generally
contain 40% to 70% crumb rubber. The purpose of our various blends is to maintain
a stable extrudeable material with appropriate characteristics.
Our material
is classified as a thermoplastic elastomer and has many of the characteristics
of materials in this group. Besides being made of recycled materials, our
rubber product can be reprocessed after it is reground. This means our material
is infinitely recyclable unless it is changed in some way (i.e. laminated
with cloth, carpet, some foams, etc.) As a result we buy back the waste from
certain customers and reprocess it into new material.
We are a custom manufacturer, producing material to our customers’ specific
requirements. Thicknesses from .045” to .500” are available in
a variety of surface patterns. Surface patterns range from matte or grained
surfaces to “v” grooves and ribbed surfaces. Additionally, we
can produce the sheet with pressure-sensitive adhesive backing.
Competing
Materials
We compete with masticated rubber in several of our applications. Masticated
rubber is manufactured by grinding up tire rubber, pouring the crumbed rubber
into a tray and applying pressure and heat to create a sheet of rubber. The
problem with this process is that it produces a somewhat rough and uneven
product. This type of sheet can be less expensive than our material, but the
lower quality of the material and the scrap disposal problems generally make
us more than competitive.
Thermoplastic
olefins (“TPO”) or thermoplastic elastomers (“TPE”)
represent a class of plastics that have characteristics similar to thermoset
rubber or vulcanized rubber with the processability of thermoplastics. These
types of plastics are infinitely reprocessable which again means that the
scrap from using these materials can be chopped up and reused without further
processing. Our material is classified as a rubber thermoplastic elastomer
(“RTPE”). The primary difference between our material and these
materials is lower cost. Currently the rubber content of our materials is
about a third of the cost of the equivalent plastic material in TPO’s
or TPE’s.
