Q1: What is the primary application field for Savinyl Orange RLS?
A: Savinyl Orange RLS is a high-performance organic pigment specifically developed for use in polyolefin masterbatches and thermoplastic compounds, particularly where excellent heat stability, dispersion behavior, and color strength are required during high-temperature processing.
Q2: Is Savinyl Orange RLS suitable for food-contact applications?
A: Savinyl Orange RLS is designed to meet regulatory expectations for indirect food contact in plastics, subject to compliance with applicable regional requirements. Its suitability depends on final formulation, processing conditions, and end-use compliance verification — users should consult Clariant’s regulatory documentation and conduct appropriate migration testing as part of their due diligence.
Q3: How does Savinyl Orange RLS perform under high-shear and high-temperature compounding conditions?
A: This pigment exhibits robust thermal and mechanical stability, maintaining consistent coloristic properties during extrusion and injection molding of polypropylene and polyethylene at typical processing temperatures up to 260 °C. It demonstrates low tendency toward degradation or color shift under standard high-shear compounding protocols.
Q4: What are the recommended dispersion guidelines for optimal performance?
A: For best results, Savinyl Orange RLS should be incorporated using standard masterbatch techniques — typically pre-mixed with carrier resin and processed via twin-screw extrusion. Good wetting and shear history are essential; dosage generally ranges from 0.1% to 2% by weight depending on the desired shade intensity and substrate opacity.
