Q1: What is the primary application field for Savinyl Orange RLSE?
A: Savinyl Orange RLSE is specifically developed for use in polyolefin-based packaging films and molded articles, particularly where high thermal stability and excellent dispersion are required during high-temperature processing such as extrusion and injection molding.
Q2: Is Savinyl Orange RLSE suitable for food-contact applications?
A: Yes — Savinyl Orange RLSE is designed to meet global regulatory expectations for pigments used in food-contact plastics. Its formulation avoids restricted heavy metals and complies with general provisions for colorants in polyolefins under major food contact frameworks, subject to final compliance verification by the compounder or converter.
Q3: How does Savinyl Orange RLSE perform under high-shear and high-temperature processing conditions?
A: The pigment exhibits robust thermal and mechanical stability, maintaining consistent hue and minimal color shift during extended residence times in extruders or injection molding units. Its optimized particle surface treatment supports uniform dispersion and reduces agglomeration even under demanding process conditions.
Q4: What is the typical dosage range for achieving full opacity and strong chroma in PP films?
A: Dosage depends on film thickness, desired shade intensity, and base resin properties, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve excellent opacity and vibrant orange tones in polypropylene films.
