Zeolex® 23 for Heat Resistance in Rubber
Silicate for Heat Resistance
Nitrile rubber compounds typically need reinforcing additives. Most will also benefit from improved properties after exposure to heat. With the addition of Zeolex® 23 silicate, compounders get two performance properties from just one versatile ingredient.
Zeolex 23 is a synthetic sodium aluminosilicate with a pH of 10, oil absorption of 75g/100g, and 8 micron particle size. Zeolex 23 is a cost-effective reinforcing agent for nitrile and other rubber compounds. It also imparts excellent retention of tensile and elongation properties after heat aging.
