Import Black Masterbatch — Buy in Bulk from Supplier in China

Shandong Luyan Color Masterbatch Co., Ltd produces the E051 series black masterbatch, a pelletized carbon black concentrate manufactured using imported carrier resin, top-grade carbon black, and compounded dispersants and lubricants. The material is specified at 50% carbon black content with a 3 x 3 mm cylindrical pellet geometry and smooth surface finish. Melt index is rated at or above 250 g per 10 minutes, volatility at 0.15%, and coloring strength at 101% against a standard reference.

The E051 series employs a special imported resin base rather than commodity polyolefin, with formulation including dispersant and lubricant additives to achieve the stated dispersion and heat resistance performance. Heat resistance and transfer resistance are both classified at level 4 and level 5 respectively on undisclosed scales, suggesting suitability for elevated temperature processing and reduced plate-out or migration in finished goods. Carbon black selection at 50% loading targets high jetness and UV shielding in thin-gauge applications.

Recommended application spans micro-plastic film, leakage-proof film, milk packaging film, water supply pipe, and cable sheath across PE, PP, EVA, PS, and ABS base polymers. The masterbatch has undergone testing at China National Center for Test of Chemical Building Material, Qilu Sinopec Resin Institute, Shandong Plastic Industry Test Center, and Shandong Sanitation Prevention Center, with SGS certification and European standard conformity claimed. Usage ratio ranges 1-4% with user-adjustable latitude. Standard packing is 25 kg per bag in paper-plastic laminate with dry, ventilated warehouse storage specified.

Shandong Luyan Color Masterbatch Co., Ltd is located at Zhenxing Road, Development Zone of the Youth Pioneer, Taian, Shandong Province, China, postal code 271000. The supplier is classified as imported-tier, harbor-trust with zero recorded response rate and no average response time data. No workforce figure, annual turnover, year of establishment, or ownership structure is disclosed in available profile information. The company positions itself as a developer and manufacturer of the E051 series, citing multi-laboratory testing and SGS certification.

The listing provides specific technical indices and claimed regulatory conformance, though certificate numbers, scopes, and validity dates are absent. The supplier references Torch Plan recommendation, a historical Chinese government technology program, as a credibility signal. Buyers should independently verify SGS certificate authenticity through SGS's online verification portal, request original test reports from the named Chinese laboratories, and confirm that the European standard cited aligns with the specific end-market regulation (EU 10/2011 for food contact, REACH for chemical registration, or RoHS for electrical applications).
