Essentials of EPDM rubber graunles

- Jan 22, 2018-

Colorful EPDM  rubber granules is  widely used for playground and kindergarten. However, what is the standard of good quality? There we give out a brief introduction of EPDM rubber granule.

Rubber content

The main component of colorful EPDM granules is a terpolymer of ethylene, propylene and non-conjugated dienes. EPDM rubber has stable chemical performance with strong wear resistance, elasticity, oil resistance, anti-aging and anti-ultraviolet. Therefore, the content of EPDM, to some extent, directly determines the chemical and physical properties of it. We produce rubber granules with different content: 10%,12%,16%,18%,20% and higher that according to customers. 10% of it can be regularly used for artificial grass infilling and for playground in the kindergarten; for runway truck,16% or 18% is either good choice; if it is the basis that is played frequently and with high intensity, 20% or higher is much suitable

Anti-aging of color 

it is not for everybody to know that what is the EPDM rubber granule prodced. In the production of EPDM particles,the dye is stirred in the raw material, and then cured but not mixed on the surface. The difference between the two is the former is the same color of the whole granules body, the latter is inconsistent inside and outside and it will be too obvious if it is worn out.So it's essential to choose a better quality of the rubber granules.


EPDM rubber granules can be produced into different diameters of 0.5-1.5mm, 1-3mm, 2-4mm, 3-5mm or customized. We can choose the suitable size for different venues use.

Glue for binder

The binder for EPDM particles is glue, and the properties of the glue directly affect the performance of the entire site. The strength of the glue directly determines the service life of the site. Glue also affects the appearance of the venue. All the particles are coated with glue, the poor glue will turn into black after curing which makes the whole spot dim while high-quality glue looks more transparent, incremental and much brighter.
