A cube blend, also referred to as a salt & pepper mix, is a proportional mix that combines a masterbatch and natural polymer into a ready-to-use package. Color consistency and quality is ensured by RTP Company and the processor avoids steps related to blending or metering accuracy. One of the main advantages compared to precolored resin is that the majority of the polymer has not been previously melted by compounding, thus preserving its original properties.

A masterbatch is pre-dispersed concentrated color that is let down with natural polymer during molding. With a precolor all the polymer is entirely compounded with the proper amount of color and delivered ready-to-use, eliminating metering and dispersion difficulties. A masterbatch offers economic advantages associated with resin purchasing and color obsolescence. Additionally, since masterbatches are not fully compounded most of the polymer used does not exhibit an additional heat history, potentially deteriorating the properties of some polymers.

Using masterbatches allows the processor to maximize their purchasing power by buying larger amounts of natural polymer. That advantage, plus lower obsolescence costs invested in end of life colors as products change give masterbatches a great economic benefit over other modes of color delivery.

Processors can also take advantage of masterbatch cost incentives, but avoid difficulties associated with monitoring proper metering by using a cube blend.

A masterbatch, also referred to as a concentrate, is a package for coloring plastics. Pigments, dyes, or other additives are dispersed into a polymer carrier which is extruded and pelletized. Those pellets are metered, or let down, into natural polymer, using a predefined ratio, during the molding process where additional mixing colors the resin entirely. Normal addition rates vary from 1 to 4%.

RTP Company uses the same production procedures, color matching equipment, and raw materials worldwide to ensure that our products can be manufactured to the same standards from one location to the next. Our production facilities are situated in the United States, Singapore, China, and France to be close to the world’s largest manufacturing centers.

Our products can be designed to meet a single or multiple requirements. You can select a standard offering from our color products and easily combine it with a standard additive masterbatch as well. Our additive masterbatches are designed to provide UV protection, antimicrobial protection, foaming, and other functional modifications for many polymers.

All color matches are completed utilizing ASTM and RTP Company documented test procedures. The final match is examined both visually and instrumentally. Instrumental analysis of the spectral data for each match is available with exhibits and lab samples.

RTP Company maintains an extensive library of active formulations. Which includes formulations that are cross-referenced to industry standards such as Pantone, Munsell, RAL, etc.

RTP Company can respond with a masterbatch solution in three working days and with precolored solutions in five days.

Our production facilities are ISO 9001:2000 registered and every batch produced is closely monitored. Samples are taken at key points in the manufacturing process and further processing cannot continue without Quality Control approval.

No product leaves our facilities without first undergoing a battery of tests to determine that the material meets or exceeds the specifications established for that product. After meeting approval with specifications, each batch is further processed to ensure uniformity throughout.

Every batch produced is given a unique lot number for both backward and forward traceability. Each shipment is double-checked for conformance to the customer’s standing and special requirements.

All incoming raw materials are approved by Quality Control prior to use and receive a bar coded label for internal tracking purposes. Many are subjected to tests in their intended application. Further, our vendors are continually monitored to ensure a uniform supply of materials that meets established requirements.
