Engineered for high tinting strength, thermal endurance, and immediate compatibility across polyolefin masterbatches, solvent-borne coatings, industrial epoxy, and eco-friendly aqueous coatings.
As the economic anchor of Central Java, Semarang—anchored by the Kendal Industrial Park (KIP), Wijayakusuma Industrial Estate (KIW), and Candi Industrial Zone—is undergoing rapid industrial upgrade. Meeting this expansion requires advanced pigment technology.
The influx of injection molding and packaging processors in Kendal requires high-purity Phthalocyanines and Azo pigments that endure polymer extrusion temperatures reaching 240°C–280°C without shade migration, blooming, or die-buildup in thin-wall polyolefin packaging.
Situated directly along the Java Sea, coastal infrastructure around Tanjung Emas Port faces extreme salinity, 85%+ relative humidity, and harsh UV radiation. Our organic pigments are optimized for lightfastness ratings of 7-8 and weatherability indices that prevent premature chalking.
With Central Java attracting global apparel giants shifting from West Java, mills demand strict Zero Discharge of Hazardous Chemicals (ZDHC Level 3) and GOTS v6.0 compliance, completely free of banned aromatic amines, heavy metal traces, and endocrine disruptors.
Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs and advanced organic pigments. Our synthesis portfolios include Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes, and Fluorescent dyes.
Backed by decades of chemical synthesis and international export experience, we have built an unyielding reputation for reliability and chemical excellence, serving global enterprises across denim, industrial textiles, footwear leather, paper converting, and thermoplastic masterbatches.
Quality consistency and ecological stewardship define our baseline. Every batch is rigorously assessed via high-precision spectrophotometers and rheological dispersibility testing before customs dispatch. Supported by complete ZDHC Level 3 and GOTS credentials, we secure regulatory compliance for your products in domestic and export markets.

In modern chemical procurement, eliminating intermediate handling reduces operational overhead and inventory buffer volatility. We operate dedicated maritime corridors connecting Tianjin and Qingdao directly to Central Java.
Our direct shipping manifests route freight smoothly into Semarang's primary maritime terminal (IDSRG), avoiding the transit delays and demurrage expenses often encountered via congested transshipment through Tanjung Priok (Jakarta) or Tanjung Perak (Surabaya).
Full tariff optimization is backed by China-ASEAN Free Trade Agreement (Form E) documentation, lowering import duty structures to 0%. All raw shipments arrive with GHS-compliant Safety Data Sheets (SDS), full elemental analysis reports, and RoHS verification certificates.
Our Tianjin synthesizing infrastructure retains complete integration backwards to fundamental raw feedstocks—Phthalic Anhydride, Cuprous Chloride, and aromatic intermediates. This insulates Semarang converters from international market price shocks and raw chemical shortages.
Cooperating with textile and paper mills over long horizons demonstrates that a factory has established an enduring and dependable foundation. Our partnerships yield consistent formulation tuning, direct cost efficiency, and dedicated capacity reservations during high-demand quarters.
Our objective is to drive client expansion by delivering reliable chemical consistency. Our technical support teams work closely with plant managers in Demak, Kendal, Ungaran, and Kudus to streamline color matching and accelerate pigment dispersion cycles on industrial extruders.
Explore our industrial dispatch and batch warehousing facilities. We handle global distribution with moisture-barrier packaging, pallet stabilization, and container-level monitoring.
Environmental care guides our synthesis methods. We engineer low-VOC, heavy-metal-free, and REACH-compliant pigments to satisfy rigorous export criteria for multinational brands.
The ZDHC (Zero Discharge of Hazardous Chemicals) Program is a collaborative movement by major global brands, retailers, and chemical manufacturers to eliminate harmful substances across the textile, leather, and polymer supply chain. Achieving ZDHC Level 3 verification affirms that our synthesis operations adhere to stringent chemical screening protocols, wastewater management, and clean input sourcing.
The Global Organic Textile Standard (GOTS) establishes stringent ecological and social criteria across the entire processing chain for organic fibers. GOTS certification validates that our chemical additives contain no banned processing chemicals, preserving worker safety and environmental integrity.
Explore our complete catalog of high-purity azo pigments, metal-complex solvent dyes, direct dye systems, and inorganic colorants for plastics, coatings, ceramics, and textiles.
Specialized reactive, acid, solvent, and sulphur dyestuffs designed for batik, garment wet processing, wood coatings, and industrial papers across Jepara, Kudus, and Semarang.
Addressing processing challenges, dispersion parameters, and procurement queries for Semarang industrial plant directors.
We apply tailored surface treatments (including rosinate, hyperdispersants, and silane coupling) to lower surface energy and minimize agglomerate formation during compounding. Our Phthalocyanine and Azo pigment powders maintain low Pressure Filter Value (FPV < 1.5 bar/g per DIN EN 13900-5), keeping screen packs clean during polypropylene and polyethylene extrusion.
Direct ocean freight voyages from Tianjin Xingang or Qingdao to Tanjung Emas Port (IDSRG) usually take 10 to 14 days. We supply full ASEAN-China Free Trade Certificate of Origin Form E documents, eliminating import duties under valid HS code classifications and streamlining customs processing.
Yes. Our color-matching laboratory uses multi-angle spectrophotometers to evaluate physical masterbatch chips, pantone targets, or liquid coating samples. We provide lab drawdowns and test batches that maintain ΔE color variation below 0.5 under standard D65 light sources.
Our pigment lines comply with heavy-metal limits, RoHS directives, ZDHC MRSL Version 3.1, and GOTS standards. Every batch ships with an updated 16-section SDS, elemental analysis verification, and certificates of analysis (COA) confirming zero presence of restricted aromatic amines.
