Brueggemann Zinc Oxide RAC

• Brueggemann Zinc Oxide RAC is an active zinc oxide, which is produced by a special precipitation process.
• Due to the gentle thermal treatment and its chemical origin, Brueggemann Zinc Oxide RAC provides excellent vulcanization properties.

• Activator for sulfur and thiuram vulcanization
• Ideal for slow reactive systems like EPDM
• Excellent cost/performance ratio
• Optimal composition for vulcanization
• Reduction of heavy metal content up to 50 % in comparison to conventional systems

Particularly suitable for activation in sulfur-cured vulcanization of all common rubber types (e.g. NR, SR, IR, SBR or NBR).

Scheme 1: Rheometer data for an NBR rubber mixture at 170°C.

Brueggemann Zinc Oxide RAC belongs to so called active zinc oxides and is well established in the rubber industry since many years. Due to its high specific surface area of ≥ 50 m²/g it enables outstanding mechanical properties - even with decreased amounts compared to conventional zinc oxides.

Rheometer curves for rubber mixtures that contain Zinc Oxide RAC show significantly higher torque values - which indicates a high crosslink density. Mechanical tests reveal according values, e.g. in tensile strength and compression set studies.

Scheme 2: Tensile values at 100%, 300% and 500% for NBR-testing bars, vulcanized with Brueggemann Zinc Oxide RAC and ZnO Red Seal.

Scheme 3: Compression set values after 24h at 100°C for NBR-testing bars, vulcanized with Brueggemann Zinc Oxide RAC and ZnO Red Seal.

• Brueggemann Zinc Oxide RAC is classified as hazardous according to the valid CLP-Regulation (H400 and H410, very toxic to aquatic life - with long lasting effect). Before commencement of operations a risk assessment must be carried out. To this end, and for ensuring the necessary protective measures, the associated safety data sheet must be noted. In addition, it must be checked whether the stated identified uses resp. specified application conditions in the safety data sheet are met.
• The aforementioned remarks are deducted from the European legal system. Deviating or additional regulations in other legal systems must be observed accordingly when using the product.
