Q1: What is the primary function of Deuteron SO 500 Oil Elastomer in elastomeric formulations?
A: Deuteron SO 500 Oil Elastomer functions as a high-performance process oil and softening agent, enhancing polymer chain mobility during compounding while contributing to improved elasticity, low-temperature flexibility, and reduced compound viscosity.
Q2: Which elastomer systems is Deuteron SO 500 Oil Elastomer typically compatible with?
A: It demonstrates excellent compatibility with saturated and unsaturated synthetic elastomers—including EPDM, NBR, SBR, and thermoplastic elastomers (TPEs)—and is commonly used in dynamic sealing, automotive hose, and vibration-damping applications where oil resistance and thermal stability are required.
Q3: How does Deuteron SO 500 differ from conventional naphthenic or paraffinic process oils?
A: Deuteron SO 500 is specifically engineered for elastomer applications with a tailored saturate content and optimized molecular weight distribution, offering superior extraction resistance, enhanced aging performance, and more consistent batch-to-batch rheological behavior compared to general-purpose process oils.
Q4: Is Deuteron SO 500 Oil Elastomer suitable for use in food-contact or potable water applications?
A: Deuteron SO 500 is not pre-qualified for direct food-contact or potable water applications. Its suitability for regulated environments must be evaluated case-by-case in collaboration with regulatory experts and end-product certifiers, based on final formulation, processing conditions, and intended use.
Q5: What guidance can you provide on recommended dosage levels?
A: Dosage is formulation-dependent and influenced by base polymer type, desired hardness, and performance targets. In most elastomer compounds, it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—though optimization through lab-scale trials is strongly recommended.
