Q1: What is the primary application area for Renol Blue B2G-HW 30?
A: Renol Blue B2G-HW 30 is specifically developed for high-temperature, high-performance engineering thermoplastics—particularly polyamide (PA6, PA66) and polyphthalamide (PPA)—where excellent thermal stability, dispersion, and color consistency are required during melt processing.
Q2: Is this pigment suitable for food-contact applications?
A: Renol Blue B2G-HW 30 is designed to meet stringent regulatory expectations for indirect food contact in plastics, subject to final formulation compliance. It contains no intentionally added heavy metals or restricted substances, and its use in food-contact systems requires validation per applicable regional regulations and end-product testing.
Q3: How does B2G-HW 30 differ from standard Renol Blue grades?
A: The “HW” designation indicates enhanced heat stability and reduced volatility under prolonged high-temperature processing conditions—critical for demanding injection molding and extrusion of engineering polymers. It also features optimized particle surface treatment for improved dispersion and reduced plate-out in processing equipment.
Q4: What is the typical dosage range in polymer systems?
A: Dosage depends on the desired shade strength and polymer matrix, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—due to its high tinctorial strength and efficient dispersion characteristics.
