Rubber agglomerate test with ASTM D 1037
Description
In this document we have data of one rubber agglomerate. The rubber agglomerate is chemically formulated by: -Water; -pré-polymer MDI 15% -N=C=O: -rubber grains; Here is showed, a sample tested constituted by 8% MDI pré-polymer, 2/100 water for a total formulated weight around 700 grams. The data was obtained on University of Minho, with the adaptation of ASTM D 1037 for flexible materials with an Instron 4505.

Steps to reproduce
For the rubber agglomerate production: 1- Measure of the quantity of water; 2- Measure of the weight of MDI pré-polymer; 3- Measure of the pré-calculated wieght of rubber grains; 4- Mix of rubber+MDI+water; 5- Pre-heating of the press until 110°C; 6- The formulated materials should be placed on a mould, with a layer of spray of white silicone; 7- When the press temperature is stabilized the sample is placed on during 15 minutes; 8- 15 minutes later the sample is removed from the press;
