Ecorr®

The explanation of the brand name and parts of the mission

together explain the reasons why reclaim is used.

Eco - Ecological

Rubber Resources strives to recycle rubber waste in order

to preserve the environment and natural resources for

future generations. Reclaim replaces virgin material in

order to take some of the pressure off our environment.

Eco - Economical

Strong costs benefits can be obtained with Ecorr®RNR

grades. Even with the current low polymer prices. As the

below recipe comparison demonstrates, there are price as

well as volume benefits.

rr - regular rubber

Waste Rubber is reversed into regular rubber, which has

regained its viscosity, chemical and mechanical properties.

Main advantageThe activities of the current company started 59 years ago

at a tyre producer. These roots still exist; nowadays the tyre

industry is the most important application for the Ecorr®

grades. The main advantage is shown below, costs savings

in a tyre application.

Cost savings per kg price and per litre. Calculated with

prices of the first quarter of 2015 and substituted up to 20%

in a Truck-Tread compound.

● Lower power consumption resulting from shorter

mixing cycles.

● Lower calendering, mixing and extrusion temperature.

● Improved penetration of fabric and cord.

● Lower swelling and shrinkage during extrusion and

calendering.

● Increased track.

● Improved reversion and ageing performance of natural

rubber compounds (ozone, UV).

● Lower raw material costs.

Key Grades

Page 6: Ecorr RNR - rubber-resources.com

www.rubber-resources.com

The processThe NR-reclaim grades are mechani-

cally and thermally devulcanised,

mainly out of rubber Truck Tread

peelings without adding any devul-

canising agents.

Rubber Resources uses a Banbury

mixer in the process; this enables

them to produce a customer-based

master batch by adding other raw

materials.

The most common applications for each material are indicated in the chart

below. It is very important to distinguish if reclaimed material is to be used as

a master batch or as part of a total compound. For each application it is possible

and / or necessary to optimise the total compound recipe.

Using reclaim in a tread compoundEach virgin compound responds differently when the reclaim is substituted for a portion of the virgin rubber, affecting

physical and processing properties such as vulcanisation behaviour. Over the years, Rubber Resources has developed

different techniques leading to full control of these affects. A brief example using a tyre tread compound is provided in

the chart mentioned below.

Example:

Using reclaim in a tread compound

In the first column, the recipe and

pro-perties of a tyre tread compound are

indicated. In the second column, the

effect of substituting 10 parts of the SBR

rubber for 20 parts of Ecorr® RNR30B01

reclaim (which contains ± 50% RHC) is

indicated. In the last two columns,

possible optimisation steps and their

effect on the compound properties are

summarized.

Increase in Mooney viscosityThe phenomenon of the hardening of

natural rubber during storage is well

known throughout the rubber industry.

Due to the high proportion of natural

rubber in tyre tread reclaim, the harde-

ning behaviour of reclaim during storage

is similar to that of natural rubber. The

rate of increase depends on storage time

and temperature. It can be calculated

with the following empirical equation:

M t = M 0 * (1 + a * t 0.55)

M t = Mooney after t days of storage

M 0 = Mooney at the day of production

t = Storage time in days

a = 0.04 for T = 23°C

= 0.15 for T = 50°C
