Product Overview

Engineering Plastic Color Masterbatches is developed for engineering-resin applications that require good dispersion, stable color and compatibility with higher-performance polymer systems. The range covers ABS / AS, PA, PC, PET and PBT carrier options, allowing the color concentrate to be matched more closely to the customer's base resin.

Colors can be customized according to customer samples, target shades or approved color references. The materials are suitable for electrical and electronic parts, appliances, automotive components, industrial products and other molded or extruded engineering-plastic applications.

Choose the Right Grade

Model	Carrier Resin	Primary Match	Typical Selection
60M	ABS / AS	ABS and AS resin systems	General housings and molded parts
70M	PA	PA / nylon systems	PA components requiring resin-compatible coloration
80M	PC	PC resin systems	PC products requiring stable appearance and dispersion
90M	PET	PET engineering-plastic systems	PET-based molded or extruded products
PBTM	PBT	PBT resin systems	PBT electrical and industrial components

Key Advantages

Carrier-resin options for major engineering plastics

What to Confirm Before Color Matching

Exact base resin and resin grade
Target color sample, Pantone / RAL reference or approved color standard
Injection-molding or extrusion process
Typical processing temperature range
Required opacity, gloss and surface appearance
Weatherability, migration resistance and environmental requirements

Color Development for Engineering Plastics

Engineering plastics can differ significantly in processing temperature, transparency, filler content and end-use requirements. For accurate color matching, the actual customer resin and processing conditions should be used whenever possible. The approved sample should then be retained as the production reference for repeat orders.

Performance Focus

Performance Area	Series Positioning	Customer Benefit
Dispersion	Good dispersion	More uniform product appearance
Weather Resistance	Grade 5-8	Supports products exposed to light and weathering
Migration Resistance	Grade 4-5	Helps reduce color transfer
Color Difference	ΔE ≤ 0.5	Supports tighter color consistency
Moisture Control	≤ 0.15%	Supports more stable processing

Note: The catalogue presents common technical indicators rather than separate performance tables for each carrier resin. The combined table therefore uses the same quality-control specifications across the five grades, with carrier resin shown as the principal difference.

Application & Processing Guidance

The correct grade should be selected according to the customer's base resin. Because engineering plastics can run at very different processing temperatures, the color formulation should be evaluated under the actual molding or extrusion conditions before final approval.

Recommended Evaluation Procedure

Confirm the exact engineering resin and grade.
Provide the target color sample or recognized color reference.
Define the processing method and temperature range.
Run a trial using the actual customer resin.
Evaluate color difference, dispersion, gloss and surface appearance.
Confirm migration, weatherability and other end-use requirements where relevant.
Retain the approved sample as the reference for repeat production.

Sample & Customization Support

Samples can be provided for color matching and application trials. For faster development, please provide the resin type and grade, target shade, processing temperature, product application, required appearance and any special weathering, migration or environmental requirements.
