Rigid Water-Resistant Masterbatch

Updated: 2026-07-18

Overview

Rigid water-resistant color masterbatch is a specialized pigment concentrate designed for plastic applications requiring durability and color stability. It is formulated with high-quality pigments and additives to ensure excellent dispersion and resistance to water, UV rays, and mechanical stress. This masterbatch is widely used in industries where long-lasting color and material integrity are critical, such as automotive, packaging, and construction. Its rigid formulation enhances the structural properties of the final plastic product while maintaining vibrant colors.

Physical and Chemical Properties

The rigid water-resistant color masterbatch typically appears as small granules or pellets, with colors ranging from standard hues to custom shades. Its density is approximately 1.1-1.3 g/cm³, and it melts at temperatures between 120-160°C, depending on the carrier resin used. Key chemical properties include insolubility in water and compatibility with most common plastic resins like polyethylene (PE), polypropylene (PP), and polystyrene (PS). The masterbatch is engineered to resist fading, bleeding, and degradation even under prolonged exposure to moisture and environmental stressors.

Main Applications

This masterbatch is extensively used in the production of plastic packaging, where water resistance and color consistency are essential. It is also a preferred choice for automotive parts, such as dashboards and exterior trims, due to its durability and UV stability. In the construction sector, it is applied in manufacturing pipes, panels, and outdoor furniture, where resistance to weathering and mechanical stress is crucial. The masterbatch ensures that the final products retain their aesthetic appeal and functional properties over time.

Safety and Storage

When handling rigid water-resistant color masterbatch, standard personal protective equipment (PPE) such as gloves and masks should be used to avoid dust inhalation or skin contact. The product should be stored in a cool, dry environment, away from direct sunlight and moisture to maintain its quality. Proper storage conditions prevent clumping and ensure consistent performance during processing. Manufacturers should also ensure that the storage area is well-ventilated to minimize any potential exposure to dust particles.

B2B Procurement Guide

When procuring rigid water-resistant color masterbatch, buyers should prioritize suppliers who provide detailed technical datasheets and sample testing opportunities. Compatibility with the base resin is critical to avoid processing issues or subpar product performance. It is advisable to request small batches for testing before committing to large orders. Buyers should also consider the supplier's reputation, production capacity, and ability to meet custom color requirements. Pricing varies based on pigment type, concentration, and order volume, so negotiating bulk discounts is often possible.
