A masterbatch is normally composed of pigments or functional additives dispersed in a carrier resin, plus a small amount of dispersing aids and processing aids. The pigment or additive content is usually 20–60%, while the carrier resin (such as PE or PP) accounts for 40–80%. The carrier makes the masterbatch easy to feed, keeps the line clean, and ensures that the pigments are well dispersed in your base polymer during processing.色母粒通常由颜料或功能性助剂、载体树脂以及少量分散剂和加工助剂组成。颜料/助剂含量一般在20%–60%，载体树脂（如PE或PP）约占40%–80%。载体的作用是便于投料、保持现场清洁，并在加工过程中帮助颜料在基体树脂中充分分散。
In production, the pigments/additives and carrier resin are accurately fed into a co-rotating twin-screw extruder. Inside the extruder, special mixing and kneading zones generate high shear to break pigment agglomerates and wet them with the molten carrier. The homogeneous melt is then filtered, strand-extruded, cooled in water, and pelletized. Key control points include feeding accuracy, temperature profile, screw design, and filter system, all of which directly affect dispersion quality and filter pressure value (FPV).在生产过程中，颜料/助剂和载体树脂通过计量系统精确加入同向旋转双螺杆挤出机。螺杆内部的混炼和捏合区产生高剪切力，将颜料团聚体打散并被熔融载体充分润湿，得到均匀熔体。熔体经过过滤后拉条、水冷，再切粒成型。关键控制点包括喂料精度、温度曲线、螺杆组合以及过滤系统，这些都会直接影响分散效果和压滤值（FPV）。
Typical carrier resins include PE (LDPE, LLDPE, HDPE), PP, EVA, PS, ABS, PA and PET. In most cases, the carrier is selected to match or be highly compatible with the customer’s base resin, for example PE carrier for PE film and pipe, PP carrier for PP injection and extrusion, and EVA carrier where flexibility and low processing temperature are needed. Choosing the right carrier helps to keep mechanical properties and processing stability of your final product.常见的载体树脂包括PE（LDPE、LLDPE、HDPE）、PP、EVA、PS、ABS、PA和PET等。实际配方中，载体通常会选择与客户基体树脂相同或高度相容的材料，例如PE薄膜和管材多用PE载体，PP注塑和挤出用PP载体，EVA载体适合需要柔软性和较低加工温度的场合。正确选择载体有助于保持最终制品的力学性能和加工稳定性。
Color masterbatch focuses on color and appearance using pigments or dyes, while additive masterbatch is designed to modify performance, such as UV resistance, anti-static behavior, slip and anti-block, flame retardancy or anti-oxidation. In many cases the two are combined, for example a black masterbatch that also contains UV stabilizers. When you issue a specification, it is important to clarify whether your priority is appearance, functional performance, or both.彩色色母的核心作用是提供颜色和外观效果，主要成分是有机或无机颜料/染料；功能助剂色母则是通过添加抗UV、抗静电、开口爽滑、阻燃、抗氧化等助剂来改变塑料的性能。实际应用中经常会出现“颜色+功能”的复合配方，例如自带抗UV的黑色母。在下达技术规格时，需要明确是优先关注外观，还是功能表现，或两者兼顾。
Compared with pigment powders, masterbatch is cleaner, easier to handle and much more consistent. Pigment dust can contaminate equipment and the environment, and it is difficult to dose precisely, which leads to color variation and more scrap. In a masterbatch, pigments are pre-dispersed in a carrier resin under high shear, so you only need a small percentage to reach the target color. This improves color stability, reduces downtime and shortens changeovers.与直接使用颜料粉相比，色母粒更加干净、易于操作且颜色一致性更好。颜料粉容易飞扬，污染设备和环境，并且计量不精确，导致颜色波动和报废率上升。而色母粒中的颜料已经在载体树脂中经过高剪切预分散，只需少量添加即可达到目标颜色，有利于稳定颜色、减少停机清理和缩短换色时间。
If the masterbatch is not well dispersed, pigment agglomerates and unmelted particles can create black specks, color dots, flow marks and streaks on the product surface. These defects lower the perceived quality and may also indicate weak points in the material. A high-quality masterbatch with excellent dispersion produces a smooth, glossy and uniform surface, which is especially important for thin films, pipes, bottles and high-end consumer products.当色母粒分散不好时，颜料团聚体或未熔颗粒会在制品表面形成黑点、色点、流痕和条纹，不仅影响外观，也可能成为材料性能的薄弱点。分散性能优良的色母粒可以带来平整、光亮、颜色均匀的表面，这对薄膜、管材、瓶类和中高端消费品尤为关键。
For outdoor applications you can choose dedicated UV stabilizer masterbatches or high-jet black masterbatches based on carefully selected carbon black. UV stabilizer systems often combine UV absorbers and HALS to match the polymer type and expected service life. Thick sections may rely more on carbon black screening, while thin films usually require tailored UV packages. The best solution should be defined together with your technical team and the masterbatch supplier based on exposure conditions.对于户外应用，可以选择专用抗UV助剂色母，或选用高黑度且炭黑粒径合适的黑色母粒。抗UV体系通常会组合UV吸收剂和受阻胺光稳定剂（HALS），并根据树脂类型和目标使用寿命进行设计。厚壁制品可以更多依赖炭黑遮光，薄膜则往往需要针对性的UV配方。最合适的方案应结合使用环境，由贵司技术团队与色母供应商共同确定。
Yes. If the carrier is not compatible with your base resin, or if the let-down ratio is too high, it can reduce impact strength, elongation and ESCR, and may weaken weld lines. Using a carrier that matches or is highly compatible with the base polymer, and keeping the masterbatch dosage within the recommended range, minimizes these risks. For critical applications, we can recommend optimized carriers or adjust the formulation to protect key mechanical properties.会的。如果载体与基体树脂不相容，或者添加比例过高，可能会降低制品的冲击强度、伸长率和环境应力开裂性能，并削弱焊接线强度。选用与基体树脂相同或高度相容的载体，并将色母添加量控制在推荐范围内，可以将风险降到最低。对于要求较高的应用，我们也可以通过优化载体或调整配方来更好地保护关键力学性能。
PE-based masterbatch can sometimes be used in PP at low addition levels, but it is not the best technical choice, especially for parts with high mechanical or heat resistance requirements. Excessive PE carrier may reduce stiffness, heat distortion temperature and weld-line strength of PP parts. For demanding PP applications we recommend PP-based masterbatch or a carefully designed universal carrier to avoid compromises in performance and processing stability.在某些要求不高的场合，PE载体色母可以少量用于PP体系，但从技术角度看并不是最佳方案，尤其是对机械性能或耐热性要求较高的PP制品。过多的PE载体可能降低PP制品的刚性、热变形温度以及焊接线强度。对于关键PP应用，我们建议使用PP载体色母或经过验证的通用载体配方，以避免对性能和加工稳定性产生不利影响。
Food-contact colorants must use pigments, additives and carrier resins that are listed and permitted in the relevant regulations, such as FDA 21 CFR in the US or EU food-contact legislation. Heavy metals, PAHs and other restricted substances must be below specified limits, and overall migration and specific migration tests may be required. For electrical and electronic products, RoHS and often REACH compliance is needed. We can provide test reports for specific grades to support your compliance documentation.用于食品接触的着色剂，其所用颜料、助剂和载体树脂必须符合相应法规的正面清单要求，例如美国FDA 21 CFR或欧盟食品接触法规中允许的物质清单。重金属、多环芳烃等受限物质必须低于限值，并可能需要进行总迁移量和特定迁移量测试。对于电器电子产品，还需满足RoHS及往往REACH的要求。针对具体牌号，我们可以提供相应的合规测试报告，方便您做产品备案和报关。
When comparing suppliers, do not look only at price per kilogram. You should also compare the required let-down ratio (LDR), impact on cycle time, scrap rate, downtime for cleaning, service response, and the cost of quality risks. A higher-priced, high-strength masterbatch that runs at 2% LDR with excellent dispersion can deliver lower cost per finished part than a cheap masterbatch that must run at 4% LDR and creates more color complaints and machine stops.比较两家色母供应商时，不能只看每公斤单价，更要比较所需添加比例（LDR）、对成型周期和废品率的影响、换色清机时间、服务响应速度以及质量风险成本。举例来说，一款单价略高但2%添加即可达到颜色强度、且分散优异的色母，在每件产品的综合成本上，往往会优于一款需要4%添加、且经常出现色差投诉和停机清理的低价色母。
Recommended tests include color and opacity measurement (L*a*b* and ΔE compared with the standard), mechanical testing on molded or extruded samples, melt flow index (MFI) and filter pressure value (FPV) for films and fibers, and accelerated weathering for outdoor grades. For regulated applications, migration tests and chemical analysis are also important. These data help you judge whether the new masterbatch can truly replace your current solution in both performance and processing.建议的验证项目包括：用色差仪测试L*a*b*和与标准的ΔE值、对注塑或挤出样条进行力学性能测试、对薄膜/纤维进行熔体流动指数（MFI）和压滤值（FPV）测试，以及对户外级别进行加速老化试验。对于受法规管控的应用，还应进行迁移试验和化学分析。通过这些数据，可以客观评估新色母在性能和加工性上是否真正可以替代现有方案。
You can monitor batch-to-batch consistency by regularly checking color difference (ΔE) against a master standard, as well as tracking key physical properties and processing behavior. A reliable supplier will keep tight internal color tolerances, retain samples for each batch, and issue COAs with traceable data. From the production line perspective, stable back pressure, screw torque and scrap rate over many batches are good signs of consistent quality.评估批次稳定性可以通过定期检测色差（相对于标准板的ΔE）、监控关键物性以及观察加工过程表现来实现。可靠的供应商会为每一批次设定严格的内部色差公差，并保留样板和出具带有追溯数据的COA。从生产线角度看，长周期内背压、扭矩、废品率等指标的稳定，同样是质量一致性的直观体现。
Red flags include heavy pigment dust and poor housekeeping, no clear material labeling or traceability, fully manual feeding without calibration, lack of written QC procedures, and very limited in-house testing. If the factory cannot explain how they handle non-conforming batches or does not keep retained samples, the risk of color fluctuation and complaints is high. A professional plant should show good dust control, accurate dosing, documented processes and sufficient lab equipment.典型的风险信号包括：车间粉尘严重、5S管理差，原料标识和追溯不清，喂料完全人工且未校准，没有成体系的检验规程，实验检测能力明显不足等。如果工厂无法说明不合格批次的处理流程，也不保留留样，那么色差波动和质量投诉的风险会非常大。专业的工厂应当具备良好的粉尘控制、精确计量、完善的文件化流程以及相匹配的实验室能力。
Global brands usually offer very strong technical support, wide certification coverage and highly standardized quality, but with a higher price and less flexibility in MOQ and lead time. A capable local manufacturer can provide more competitive cost, faster response and more flexible logistics, provided that their process control, documentation and testing capability are at the required level. For strategic grades or markets with strict certification requirements, global brands may be preferred; for cost-sensitive or fast-moving projects, a trustworthy local supplier can deliver better TCO.跨国品牌通常拥有很强的技术支持能力、更全面的认证覆盖以及高度标准化的质量体系，但价格较高、起订量和交期灵活性相对较低。有能力的本地优质制造商，则可以在保证工艺控制、文件体系和检测能力达标的前提下，提供更具竞争力的成本、更快的响应速度以及更灵活的物流服务。对于认证要求极高的战略产品，全球品牌可能更合适；对于对成本和交期敏感的项目，一家稳定可靠的本地供应商往往能带来更好的综合TCO。
